CHAPTER 1 INTRODUCTION 1.1 Research background

Each organization has its own assets which contains two main components – labor and capital Capital is so important to the achievement of the business, while

labor is the vital factor for creating profits to it The labor does everything daily and

the whole existing time of the organization The reality of working life today is that

employees are frequently trying to control their work and personal lives

In the context of integration into the world economy, along with the introduction of many domestic petroleum companies and foreign petroleum

companies have made the competition attract high-quality human resources to be

more intense Therefore, the vital importance which leaders should perform are to

retain current employees because the stability of personnel will help organization save

time, costs of recruitment, training According to Tett and Meyet (1993), job

satisfaction is negatively associated with turnover intention Job satisfaction was

associated with decreased intentions to leave a company (Hom & Griffeth, as cited in

Valentine et al., 2011; Jaramillo, Mulki & Solomon 2006) Thus, besides the ways to

improve business efficiency, management efficiency, cost savings, etc the methods to

improve the job satisfaction of employees are the concern of all organization

The job is considered an important part of human life since the majority of their lives is devoted to the organization Many people believe that the work represents

their value in society Therefore, the quality of life will depend on the quality of work

life which they have been at the workplaces Improving the quality of work life will

contribute to bring good quality of life for each individual

Quality of work life including the life aspects related to the work such as wages, working hours, work environment, benefits, career prospects, the human

relationship, the balance between work and life These aspects contribute to the

satisfaction and motivation of employees According to Efraty, Sirgy and Claiborne

(1991), high quality of work life results in an increase in job satisfaction and

performance of employees, and at the same time, cause a decrease in both alienation

and turnover intention From that, employees are willing to contribute to an

Trang 11

organization where quality of work life exists because they feel that their work fulfills

their needs (Cascio, as cited in Koonmee, Singhapakdi, Virakul, and Lee, 2010)

Recent studies have shown that quality of work life is not the unique factor affecting to job satisfaction of employees, the institutionalization of ethics is also

considered the important factor influencing to employees’ job satisfaction According

to Sims and Kroeck (1994), ethical working environment is an important factor in the

person-organization study That is, employees usually choose to work in organizations

whose ethical preferences fit their own And so, employees who work for

organizations that institutionalize ethics would tend to be more satisfied with their

jobs (Singhapakdi & Vitell, 2007) And finally, Valentine, Godkin, Fleischman, and

Kidwell (2011) indicated that corporate ethical values and job satisfaction were

associated with decreased turnover intention

Therefore, it is necessary to study the association between institutionalization

of ethics, quality of work life and job satisfaction Because of in parallel to the

importance of ethics institutionalization, both quality of work life and job satisfaction

have been important topics in human resource and organizational development

(Leopold, as cited in Koonmee et al., 2010)

The oil and gas company is a type of specific enterprise, operating in the field

of petroleum exploration and production Its operation and business are conducted

through laborers The works at the oil and gas company is considered to be extremely

stressful, contain many risks, frequently long working hours, working fully stretched

in harsh environments and often facing danger, be able to occur injury or even

dangerous to life Such as explosives, gas eruption, falling into the sea, labor accidents

due to work with heavy machinery, etc although safety regulations are very closely

on the rig To work well in the petroleum sector, employees need more skills such as

analysis, synthesis, teamwork and have good health Besides, the petroleum sector is

the operation field related to exploration and production of natural resources therefore

the intelligence is pre-requisite for the employees working there In addition, soft

skills are such as presentation, conflict resolution, establishing good relations with

colleagues; fast processing unexpected problems occur, etc those are the important

skills which staffs need to equip themselve Therefore, when there is an employee

Trang 12

meeting the above requirements, any petroleum company which wishes to maintain

existing staff and make them meet the job satisfaction to engage with the organization

in the long-term, especially employees with high technical qualifications The research

of Al Muftah and Lafi (2011) related to petroleum industry in Qatar supports that

quality of work life is positively and significantly related to employees’ job

satisfaction Regarding the importance of ethics and quality of work life and the effect

of them on job consequences such a job satisfaction of employee and spirit of team

work, Chamesghali and Salimiare (2014) considered the relationship between ethics

institutionalization, quality of work life and job-related outcomes in the form of case

study of employee of national Iranian oil product distribution company

Nowadays, the common problem of the petroleum company is to improve the job satisfaction of employees, creating incentives for employees to work effectively

and engage long-term with the organization Therefore, the determination of the

degree of influence of the ethics institutionalization and the quality of work life to the

job satisfaction of petroleum employees is a necessary matter

1.2 Research problem

For the last decade, organizations have increased effort to institutionalize ethics, partly because such efforts positively affect employee behavior In addition,

given increasing ethical problems in business, many organizations have tried to

control these problems by institutionalizing ethics Therefore, ethics

institutionalization is not only a process developed through continual ethical operation

but also an important topic in business ethics research and ethics become

institutionalized by “the persistence of specific behaviors associated with an

organization and its employees behaving ethically” (Sims, 1991, p 494)

According to Purcell and Weber (1979), mechanism for ethics institutionalization within an organization is the utilization of a code of ethics This

code describes the general value system of the organization, defines the purpose of the

organization, and provides guidelines for decision-making consistent with these

principles Ethics institutionalization is a part of the organizational environment, and it

is also an important determinant of the decision-making processes of employees in

situations involving ethical issues (Hunt & Vitell, 1986; Ferrell & Gresham, 1985)

Trang 13

Sims (1991) also discusses the important of institutionalizing organizational ethics and

emphasizes the importance of an ethically oriented culture to ethics institutionalization

within organizations

In recent years, the ethics institutionalization is also an important responsibility for organizations in order to effectively counteract the frequent occurrences of

unethical and illegal behavior within organizations An organization can utilize

different methods to create an ethical work culture for employees, especially ethical

practices can be a powerful tool for enhancing an organization One of methods is to

institutionalize ethics in business organizations and Koonmee, Singhapakdi, Virakul,

and Lee (2010) emphasized that ethics, quality of work life and job-related outcomes

are identified as progressive indicators related to the function and sustainability of

business organizations

Much research has expected that people in organizations with a high degree of institutionalization of ethics will be more satisfied with their jobs Such as,

Singhapakdi and Vitell (2007, p 287) argue, “organizations that institutionalize ethics

appear to value integrity and trust and, as a result, often treat their employees more

fairly in terms of compensation, performance evaluation, promotion and conflict

resolution” Accordingly, organizations that institutionalize ethics pay attention to the

quality of their employees work life will get the advantages of having more committed

workforce and more commitment of workforce

Much research has documented that institutionalization of ethics is an important factor affecting various aspects of employees’ job-related outcomes Such

as, Vitell and Davis (1990) found a direct link between job satisfaction and ethical

behavior, the organizational culture is a key component when looking at ethical

behavior Turban and Greening (1996) investigated the affecting of ethics programs

and perceived corporate social responsibility positively on individual work attitudes,

namely job satisfaction Vitell and Singhapakdi (2008) investigated the impact of

ethics institutionalization on job-related outcomes (job satisfaction, esprit de corps,

and organizational commitment) for marketing professionals and revealed that

implicit institutionalization is a significant determinant of job satisfaction, but explicit

institutionalization is not Kang (2010) investigated the relationship between job

Trang 14

satisfaction and ethical conflict, ethical conflicts causes and consequences of job

dissatisfaction and came to the conclusion that many employees confirm the existence

of ethical conflict in their workplace Valentine, Godkin, Fleischman, and Kidwell

(2011) examined the degree to which perceived corporate ethical values work in

concert with group creativity to influence both job satisfaction and turnover intention,

and indicated that corporate ethical values is associated with increased job

satisfaction

Much research also has documented that institutionalization of ethics is studied

in various countries with different fields Such as, Koonmee et al (2010) investigated

the relationship between institutionalization of ethics, quality of work life and

employee job-related outcomes and concluded that implicit institutionalized ethics has

a positive relationship with quality of work life; implicit institutionalized ethics and

quality of work life have positive impacts on Thailand staff working results (job

satisfaction, team working and organizational commitment) Furthermore, based on

the previous research, Marta, Singhapakdi, Lee, Sirgy, Koonmee, and Virakul (2013)

examined the perception of institutionalization of ethics and quality of work life for

Thailand marketing managers versus American marketing managers, the results

showed that the impact of institutionalization of ethics on the quality of work life for

Thai managers is more than American managers because Thailand culture is

collective, while American culture is individual

In addition, Torlak, Tiltay, Ozkara, and Dogan (2014) analyzed the relationship between institutionalization of ethics and quality of work life by mid-level managers

working in the private sector in Turkey and came to the conclusion that implicit

institutionalization of ethics is positively related to both higher and lower needs that

determine quality of work life Lee, Yu, Sirgy, and Singhapakdi (2015) investigated

the effect of ethics institutionalization on employee’s work life experiences (job

satisfaction, organizational commitment, spirit de corps, quality of work life) and

overall life satisfaction (life satisfaction, employee happiness), data were collected

through a survey of marketing managers in Italy, and came to the conclusion that

implicit institutionalization of ethics has a positive effect on not only employees’

quality of work life but also job satisfaction

The research of Al Muftah and Lafi (2011) related to petroleum industry in Qatar supports that the physical, psychological and social factors’ centrality have a

significant relationship with quality of work life which indirectly impact employees’

satisfaction The finding indicated that quality of work life is positively and

significantly related to employees’ job satisfaction Regarding the importance of

ethics and quality of work life and the effect of them on optimized performance of an

organization and job consequences such a job satisfaction of employee and spirit of

team work, Chamesghali and Salimiare (2014) considered the relationship between

ethics institutionalization, quality of work life and job-related outcomes in the form of

case study of employee of national Iranian oil product distribution company

Reichert, Webb, and Thomas (2000) examined the relationships between ethical and industry type Industries, such as computers, electronics, scientific and

photo graphics sectors, that are involved with high precision products and industries;

such as mining, crude oil, and petroleum refining, that utilize natural resources are

more inclined to have a formal written a code of ethics and social responsibility

Institutionalization of ethics is gaining more and more importance in business life day by day (Torlak et al., 2014) Moreover, the importance of understanding more

about the institutionalization of organizational ethics should be apparent because it is

really good strategy for a company to concern about and adapt institutionalization of

ethics (Purcell & Weber, 1979) However, there are very few studies about this subject

in samples of Vietnam culture Particularly, there have been very few studies on the

relationships between ethics institutionalization and quality of work life, and between

ethics institutionalization and job satisfaction (Koonmee et al, 2010)

From above discussions, it is necessary to study the association between institutionalization of ethics, quality of work life and job satisfaction Because of in

parallel to the importance of ethics institutionalization, both quality of work life and

job satisfaction have been important topics in human resource and organizational

development (Leopold, as cited in Koonmee et al., 2010) Thus, the main issue of this

study is to understand the relationship between institutionalization of ethics, the

perception of the quality of work life and job satisfaction of employees in Vietnamese

Petroleum Industry in particular and in Vietnam business organization in general

1.3 Research objectives

The main focus of the study is to empirically examine a model that focuses on the effects of ethics institutionalization on employees’ quality of work life and job

satisfaction Furthermore, the study also examines the mediating effect of quality of

work life on employees’ job satisfaction

Specifically, the study aims to investigate the following relationship:

1 The relationship between quality of work life and job satisfaction

2 The relationship between ethics institutionalization and quality of work life

3 The relationship between ethics institutionalization and job satisfaction

1.4 Research scope

This research focuses on investigating the impact of implicit and explicit ethics institutionalization on employees’ quality of work life and job satisfaction, as well as

the mediating effect of quality of work life on job satisfaction of employees in

Vietnamese petroleum industry

Almost the oil and gas companies have located in Ho Chi Minh City, Hanoi City and Vung Tau City Moreover, basing on the advantages of communication with

the oil and gas company’s authorities, this research may conveniently conduct the

survey questionnaire via paper and online in these cities

1.5 Research significance

This research contributes to the understanding of ethics, quality of work life and job satisfaction and especially the important role of institutionalizing ethics, the

extent to which its impact on employees’ quality of work life and job satisfaction

within the context of Vietnamese business organizations in generally and within

Vietnamese petroleum industry in particularly

The findings provide a significant opportunity for managers perceives that some aspects of employees’ quality of work life can have a positive predictive impact

on their job satisfaction Based on this finding, it is very important for business

organizational management to design work requirements, build appropriate policy in

order to improve employees’ quality of work life, as well as, so that employees can

enhance job satisfaction in organization, have a balanced life at work and with family

CHAPTER 2 LITERATURE REVIEW

This chapter gives a specific view about the important constructs of the study, presents a discussion of job satisfaction, quality of work life and institutionalization of

ethics This is followed by the development of hypothesis and construction of a

conceptual model Five hypotheses are also proposed after being argued based on

previous researches

2.1 Job satisfaction

An employee’s overall job satisfaction is composed of several aspects such as satisfaction with compensation, satisfaction with top management, satisfaction with

promotions and satisfaction with coworkers

According to Spector (1988), job satisfaction is important from two perspectives: first, from the human aspect, employees should be treated fairly and be

respected Second, behavioral aspects, attention to job satisfaction could direct the

behavior of employees, so that it would affect the performance and organizational

responsibilities and lead to positive and negative behavior from them

Thus, job satisfaction is the essential component for employee motivation and encouragement towards better performance Many previous researches have defined

job satisfaction over the years For instance, Hoppok and Spielgler (1938) defines job

satisfaction as the integrated set of psychological, physiological and environmental

conditions that encourage employees to admit that they are satisfied or happy with

their jobs Locke (as cited in Valentine et al., 2011, p 6) defines job satisfaction as “a

pleasurable or positive emotional state due to appraisal of one’s job experience”

Accordingly, once a person feels satisfied, they are willing to participate in work

positively and this leads to improve their quality of work life In addition, job

satisfaction is also the one attitude that is related to an organization’s ethical context,

particularly where there is strong belief that the organization and its leaders truly

promote the ethical conduct (Vitell & Davis, 1990)

Much research also has documented that job satisfaction is studied in various relationship within an organization Such as, the relationship between job satisfaction

and turnover intention has been evaluated extensively in the organizational literature,

and the result generally shows that job satisfaction was associated with decreased

Trang 19

10

intentions to leave a company (Hom & Griffeth, as cited in Valentine et al., 2011;

Jaramillo, Mulki & Solomon 2006); another finding indicates that job satisfaction is

negatively associated with turnover intention (Tett & Meyet, 1993) Finally, Valentine

et al (2011) indicated that corporate ethical values and job satisfaction were

associated with decreased turnover intention

Much research also has documented that job satisfaction is studied in the human aspect For instance, the motivational factors, such as the nature of work, the

sense of achievement, the recognition, the responsibility, and opportunities, that helps

employees to find their worth with respect to value given to them by organization

(Baah & Amoako, 2011) Further, this can increase motivational level of employees

which will ultimately raise internal happiness of employees and the internal happiness

will cause satisfaction Thus, the role of employees at workplace is emphasized as

there is an influence of various elements on an employee within the organization

(Raziq & Maulabakhsh, 2015)

The recent research emphasizes that job satisfaction is a pleasurable or positive emotional state and also the most controversial concepts in organizations Based on

the foundational and theoretical efforts, it is very important not only towards

employees but also at all levels of management and organizational human resource

(Etebarian & Yazdi, 2016) Besides, job satisfaction in an important factor in

increasing productivity, sense of belonging towards workplace, increase quantity and

quality of work, good human relation at work, raise morale, create interest in the work

and reduce stress In contrary, declining in job satisfaction leads to excessive

absenteeism, low efficiency, displacement and transfer of employees

Based on the above literature, it is necessary to study the importance of job satisfaction of employees within organizations, especially examining the factors

affecting on the job satisfaction

2.2 Quality of work life

In recent years, many business organizations fail to understand the importance

of working environment for employees’ job satisfaction and thus face a lot of

difficulties during their work (Aiken, Clarke & Cloane, 2002) Employee is an

essential component in the process of achieving the mission and vision of a business

Trang 20

11

organization Employees should meet the performance criteria set by the organization

to ensure the quality of their work In order to meet the standards of the organization,

employees need a working environment that allows them to work freely without

problems that may restrain their working performance

In addition, Lawler (as cited in Narehan, Hairunnisa, Norfadzillah &

Freziamella, 2014) refers that quality of work life have relationship to job

characteristics and working environment because the whole quality of work life in the

organization goals is to improve employee’s well-being and support from

productivity Thus, the objective of this research is to analyze the impact of working

environment as well as quality of work life on employees’ job satisfaction

In over the years, the quality of work life is defined by many researches in the various aspects For instance, Shamir and Solomon (1985) define quality of work life

as a comprehensive construct that includes well-being related to the extent to which

work experiences are rewarding, fulfilling, and reduce stress Beukema (as cited in

Narehan et al., 2014) refers quality of work life as the extent to which employees are

able to configure their jobs in accordance with their options, interests and needs in the

organization Walker’s (as cited in Koonmee et al., 2010) definition, quality of work

life involves promoting a work environment favorable to the satisfaction of

employees' needs And then, Quality of work life is defined as “employee satisfaction

with a variety of needs through resources, activities, and outcomes stemming from

participation in the workplace” (Sirgy, Efraty, Siegel & Lee, 2001, p 242)

The construct of quality of work life has been defined as the relating to job characteristics and working environment (Lawler, as cited in Narehan et al., 2014),

employee’s well-being (Shamir & Solomon, 1985), the options, interests and needs of

employees (Beukema, as cited in Narehan et al., 2014), and the satisfaction of

employees’ needs (Walker, as cited in Koonmee et al., 2010) To facilitate the

discussion that relates quality of work life with job satisfaction, this study will adopt

the need satisfaction approach to quality of work life (Sirgy et al., 2001) That is,

quality of work life is defined as employee satisfaction with a variety of needs through

resources, activities, and outcomes stemming from participation in workplaces

Trang 21

12

Based on need-hierarchy theory (Maslow, as cited in Koonmee et al., 2010), Sirgy et al (2001, p 241) propose that quality of work life is measured in terms of

employees' needs Specifically, seven dimensions of needs are suggested:

a) Health and safety needs (protection from ill health and injury at work and outside of work, and enhancement of good health);

b) Economic and family needs (pay, job security, and other family needs);

c) Social needs (collegiality at work and leisure time off work);

d) Esteem needs (recognition and appreciation of work within and outside the organization);

e) Actualization needs (realization of one's potential within the organization and as a professional);

f) Knowledge needs (learning to enhance job and professional skills); and g) Aesthetic needs (creativity at work as well as personal creativity and general aesthetics)

According to their research into different dimensions of need-based quality of work life, Koonmee et al (2010) and Marta et al (2013) categorize quality of wok life

into two major categories: lower and higher order needs

Lower-order quality of work life: Lower-order quality of work life is the organizational

programs designed to meet the needs related to security, health, family and economic

Higher-order quality of work life: Higher-order quality of work life is the organizational programs designed to meet the needs related to community, self-esteem, self-actualization, knowledge and aesthetics

Why the quality of work life is important? Some studies have shown that quality of work life could affect employees’ behavioral responses such as

organizational identification, job satisfaction, job involvement, job effort, job

performance, and turnover intention (Etebarian & Yazdi, 2016) Walton (as cited in

Narehan et al., 2014) emphasizes that quality of work life was an important approach

to save human and environment values which have been ignored due to technological

advancement of the economic growth and productivity Once the employees

experience enjoyment in working at an organization, they would feel satisfied and

influence their commitment in their daily tasks High quality of work life results in an

Trang 22

13

increase in job satisfaction and performance of employees, and at the same time, cause

a decrease in both alienation and turnover intention (Efraty, Sirgy & Claiborne, 1991)

Furthermore, the quality of work life also has the significant impact to the society A happy employee will experience the positive feeling and this feeling is

carried to their family and the society Thus, since today’s life demand is quite

stressful, quality work life is important as it contributes to the environment as well as

family structure by offering ways to fulfill individuals’ responsibilities (Bagtasos,

2011)

The mainstream research on quality of work life has been linked to employees' job-related outcomes such as productivity, job satisfaction, and employees'

commitment For example, the research findings from Lau and May (1998) suggest

that companies with high quality of work life can also have high customer satisfaction

which, in turn, will provide higher growth and profitability to the companies

Greenhaus, Bedeian, and Mossholder (1987) suggested that quality of work life is

related to employees’ satisfaction and work related behaviors Cascio (as cited in

Koonmee et al., 2010) argues that employees are willing to contribute to an

organization where quality of work life exists because they feel that their work fulfills

their needs

Moreover, quality of work life involves the opportunity to make decisions about employees' job and the design of their workplaces Consistently, the recent

study reveal that quality of work life generally has a positive influence on job

satisfaction, organizational commitment, and esprit de corps (Lee, Singhapakdi &

Sirgy, 2007) In another study by Koonmee et al (2010), quality of work life mediates

the relationship between institutionalization of ethics in firms with job-related

outcome

These studies indicate that, once quality of work life programs are presented in

a business organization, employees will feel satisfied towards their job And so, the

job satisfaction has a significant relationship with the quality work life

In fact, some experts have raised the quality of work life as a hierarchy of concepts including life satisfaction (on the top of the hierarchy), job satisfaction (in

Trang 23

14

the middle of the hierarchy) and satisfaction from certain aspects such as pay

satisfaction, colleagues, and supervisors (Champoux, 1981)

A large number of employees in the oil & gas companies in Qatar are playing a significant role for economic growth Based on this context, Al Muftah and Lafi

(2011) focus on identifying the factors that associated with employees’ satisfaction

and their quality of work life More specifically the study is held to identify the

relationship between quality of work life and employees’ satisfactions This is

especially true as quality of work life is less emphasized in Asia as compared to North

America and European countries (Bagtasos, 2011; Wyatt & Wah, 2001) Looking

back at Vietnam, Vietnam is also a country in Asia, Vietnam is also developing oil

and gas industry, so it is necessary to have a study on the relationship between quality

of work life and job satisfaction

Based on the above discussions, this study aims to expect the quality of work life to have a positive influence on job satisfaction Thus, the hypothesis is proposed

as the following below:

Hypothesis 1 (H1): Quality of work life is positively related to job satisfaction

2.3 Ethics institutionalization and Quality of work life

In recent years, due to increasing ethical problems, many business organizations have established ethics programs to help improve ethical behavior and

to help prevent ethical problems among their employees (Valentine & Fleischman,

guardrails to keep corporate wayfarers on track”

Goodman and Dean (as cited in Sims, 1991) referred an institutionalized act as

a behavior that is performed by two more individuals, persists over time, and exists as

a part of the daily functioning of the organization

Trang 24

15

Singhapakdi and Vitell (2007, p 284) defined the institutionalization of ethics

as “the degree to which an organization explicitly and implicitly incorporates ethics

into its decision-making processes”

To make possible the discussion that relates institutionalization of ethics with quality of work life, this study will adapt “institutionalization of ethics” as the degree

to which an organization explicitly and implicitly incorporates ethics into its

decision-making processes, a definition by Singhapakdi and Vitell (2007)

According to Brenner (1992), there are two categories of ethics programs in organizations — either explicitly created or implicitly inherited Based on his

research, the explicit components include codes of ethics, policy manuals, ethics

seminars, internal control systems, and ethics staff The implicit components include

corporate culture, incentive systems, valued behaviors, promotion policies, and

number of people in the organization behaving according to its ethics, and the degree

to which it exists as part of the organization

When organizations create an environment that makes their employees behave and act persistently according to their ethical values and policies, those organizations

are considered to have institutionalized their ethics (Koonmee et al., 2010)

Thus, since ethical problem is increasing in the business organization, ethics institutionalization is important as it is one of the most effective methods for business

organizations to overcome the ethical problems they have faced in over years

Ethics and the quality of work life are closely related to each other Studies show that ethics positively influence the quality of work life and employees’ job

Trang 25

performance (Shaw, as cited in Torlak et al., 2014) Besides, acting in accordance with

ethical values and policies in an organization, and creating an organizational

environment promoting them, also has a positive influence on the quality of work life

(Ferrell, Fraedric & Ferrell, as cited in Koonmee et al., 2010)

The purpose of a study by Lee et al (2015) is to examine the effects of ethics institutionalization on employee experiences in work life and overall life satisfaction

The results indicate that implicit ethics institutionalization does indeed have a positive

predictive effect on job satisfaction, esprit de corps, organizational commitment and

quality of work life

Koonmee et al (2010) examines the relationship between institutionalization of ethics, quality of work life and job-related outcomes and concludes that implicit ethics

institutionalization has a positive association with quality of work life

Also, in a study on ethics institutionalization and the quality of work life, Marta

et al (2013) compare American and Thai marketing managers and find that Thai

businesses organizations have a higher tendency towards implicit ethics

institutionalization than American business organizations Especially, they have found

no significant differences in levels of explicit ethics institutionalization However,

Singhapakdi, Sirgy, Lee and Vitell (2010) have documented that explicit ethics

institutionalization has a positive effect on implicit ethics institutionalization and,

therefore, this could have a positive effect on the quality of work life

In summary, the above evidences suggest that institutionalization of ethics could be closely associated with the quality of work life (Marta et al., 2013; Koonmee

et al., 2010; Singhapakdi et al., 2010; Vitell & Singhapakdi, 2008)

Based on the above arguments, this study aims to expect the ethics institutionalization to have a positive influence on quality of work life Thus, the

hypothesis is proposed as the following below:

Hypothesis 2a (H2a): Implicit ethics institutionalization is positively related to quality of work life

Hypothesis 3a (H3a): Explicit ethics institutionalization is positively related to quality of work life

Trang 26

2.4 Ethics institutionalization & Job satisfaction

In organizational working environment, job suitability and ability to handle conflicts at work also have a positive impact on an employee’s satisfaction (Dubinsky,

Howell, Ingram & Bellenger, 1986) Accordingly, Sims and Kroeck (1994) argue that

ethical working environment is an important factor in the person-organization study

That is, employees usually choose to work in organizations whose ethical preferences

fit their own And so, employees who work for organizations that institutionalize

ethics would tend to be more satisfied with their jobs (Singhapakdi & Vitell, 2007)

One reason, which makes an organization institutionalize ethics, is to value integrity and trust In fact, according to a study by Moorman (1991), there is a positive

causal relationship between perceptions of organizational justice and job satisfaction

More recently, a study of salespeople by Schwepker (2001) indicates that there is a

positive association between their perceptions of a positive ethical climate and job

satisfaction

Organizational culture is considered as one of the most important tools in the study of organizations (Schwartz & Davis, 1981) There is a direct relationship

between ethical behavior in organizations and corporate cultures because corporate

cultures, one of categories of implicit ethics institutionalization, set the moral tone for

organizations (Sims, 1992) Ethics training, one of categories of explicit ethics

institutionalization, is another valuable tool that is used to raise the ethical

consciousness of employees in organizations (Callan, 1992; Thompson, 1990)

Based on the research of Singhapakdi and Vitell (2007), their survey of American marketing practitioners, they argue that relationship between

institutionalization of ethics and job satisfaction have been significant issues because

organizations that institutionalize ethics appear to value integrity and trust and, as a

result, are often more likely to treat their employees fairly And in the same study,

they examine the effects of two dimensions of ethics institutionalization on perceived

importance of ethics, job satisfaction, esprit de corps and organizational commitment

and conclude that implicit ethics institutionalization is a significant determinant of job

satisfaction, but explicit institutionalization is not

Trang 27

in human resource management, organizational development, and business ethics

Lee et al (2015) argue that ethics institutionalization has a positive effect on job satisfaction for the following reasons Ethics institutionalization is an

environmental factor affecting individual employee’s ethical decision making Ethics

institutionalization fosters an ethical work climate within the organization Employees

are likely to be satisfied with their jobs when they are working for an ethical firm

(Chan & Lam, 2011; Valentine & Fleischman, 2008) Thus, institutionalization of

ethics should reduce the incident of unfair treatment within the organization and

enhance employee’s sense of security in the workplace Feelings of security in the

work place should increase employee job satisfaction

Based on the above discussion, this study aims to expect both implicit and explicit ethics institutionalization to have a positive influence on job satisfaction

Thus, the hypothesis is proposed as the following below:

Hypothesis 2b (H2b): Implicit ethics institutionalization is positively related to job satisfaction

Hypothesis 3b (H3b): Explicit ethics institutionalization is positively related to job satisfaction

CHAPTER 3 RESEARCH METHODOLOGY

This chapter presents a details account of a research methodology of this study

First, it starts with the research design, including qualitative research, main survey

method and research process After that, measurement scales are presented to develop

questionnaire, the preliminary evaluation of research scales is conducted to help

measurement scales clearer and understandable Followed by sample size and sample

method Beside, this chapter also introduces the official method of research

3.1 The research design

As mentioned in the literature review part, this topic has just taken in marketing while never done at any petroleum industry in the past Thus, the questionnaires had to

take a deep consideration though being developed by many previous studies to make

sure the sufficient application in the oil and gas industry Accordingly, the research

design was separated into two phases: the pilot test as a qualitative research and the

main survey as a quantitative research

The survey questionnaires was originally designed in English and then translated into Vietnamese by the researcher with the support of some English experts

understood The procedure of conducting in-depth interviews started with specifying

the objectives of the research in terms of what information was needed to be collected

Then the detailed questionnaire was shown to the respondents for checking their

understanding During the interview, the researcher also wanted to find out if the

chosen measurement scale was suitable for conducting the research in Vietnam All

the comments from the interviewees were gathered with the aim to modify the

measurement scale

Trang 30

21

Based on the feedback of respondents, the survey questionnaire was slightly modified to make it clearer and more understandable (see appendix 1)

3.1.2 Main survey method

The main survey was conducted in the large scale with all the positions of employees who are working for companies related to the oil and gas industry

The methods of collecting information were personal interviews, directly filling out the paper form and, also, indirectly filling via online version of questionnaire

To access the degree of respondent’s answer, Likert scale was used in the answer sheet (from 1-strongly disagree to 5-strongly agree) The questionnaire firstly

prepared in English, and then was translated Vietnamese in order to make sure the

respondents could understand clearly those mentioned constructs

3.2 Measurement scale building

From the literature reviews and the research model as referred above, measurement carefully given out to make sure the appropriation of research cope

All the constructs in the model were measured with multiple items, which were developed by other researches and also based on the results of qualitative study to

adequately capture the domain of the constructs

 Implicit ethics institutionalization was measured by nine items (Singhapakdi &

Vitell, 2007; Vitell & Singhapakdi, 2008; Koonmee et al., 2010; Marta et al., 2013; Torlak et al., 2014; Lee et al., 2015)

 Explicit ethics institutionalization was measured by seven items (Singhapakdi

& Vitell, 2007; Vitell & Singhapakdi, 2008; Koonmee et al., 2010; Marta et al., 2013; Torlak et al., 2014; Lee et al., 2015)

 Quality of work life was measured by sixteen items (Sirgy et al., 2001;

Koonmee et al., 2010; Noor & Abdullah, 2012; Marta et al., 2013; Torlak et al., 2014; Lee et al., 2015)

 Job satisfaction was measured by five items (Dubinsky et al., 1986; Paolillo &

Vitell, 2002; Vitell & Singhapakdi, 2008; Koonmee et al., 2010; Lee et al., 2015)

In the research measurement scale, implicit ethics institutionalization, explicit ethics institutionalization, quality of work life and job satisfaction, all was the first-

order constructs In addition, quality of work life was also the mediating variable

Total 37 questions were presented in Table 3.1

variables However, it should not be less than 100 to guarantee the correct analysis

result As the formula is below:

 n >= 100 and n > = 5k (k: number of variables)

In this research, k = 37 questions Therefore, the minimum needed for the research is 185 answers To conduct Structural Equation Modeling (SEM), Garver and

Mentser and Hoelter (as cited in Mohamad & Mohamed, 2012) proposed a “critical

sample size” of 200 Thus, in this research, 200 questionnaires were essential for the

required sample size

Sampling method:

In association with the theoretical literature, other researches and the results of qualitative phase, the final questionnaire was given out to implicating the main survey

(see appendix 2 & appendix 3)

Trang 36

27

To adapt the research objectives as mentioned above, the data was obtained from the employees who are working for the companies related to Vienamese

petroleum industry and there were several companies to be chosen from three cities

such as Hanoi, Ho Chi Minh, Vung Tau due to the convenience

3.4 Data analysis method

The SPSS (Statistical Package for Social Science) version 20.0 and Amos 20.0 were used in this research for analyzing primary data The researcher ran Amos 20 for

SEM with purpose of enhancing the value of the model

Reliability analysis is used to evaluate the reliability of the measurement scale;

this analysis requires calculating Cronbach’s Alpha Cronbach’s Alpha should be

above or at least equal 0.6 to adapt internal reliability and the correlation of each

specific item with total of the other items in the scale was quite high or higher than 0.3

(Nunnally & Burnstein, as cited in Nguyen, 2011)

After evaluating the scale reliability, the Exploratory Factor Analysis (EFA) method is applied to identify the number of underlying factors that explain the

correlations among a set of variables as well as to test the convergent validity and

discriminant validity Convergent validity shows the degree in which two

measurement of the same concept are correlated (Hair et al., 2010) while discriminant

validity states that two measurement scales are used to measure two different concepts

need to be discriminant from each other

Confirmatory factor analysis as also run to test the model fit As shown:

 The Chi-square test indicates the amount of difference between expected and observed covariance matrices A Chi-square value close to zero indicates little

difference between the expected and observed covariance matrices In addition, the

probability level must be greater than 0.05 when Chi-square is close to zero (Hu &

Trang 37

28

 Root Mean Square Error of Approximation (RMSEA) is related to residual in the model RMSEA values range from 0 to 1with a smaller RMSEA value indicating

better model fit Acceptable model fit is indicated by an RMSEA value of 0.06 or less

(Hu & Bentler, 1999)

Then, structural equation modeling (SEM) tested the hypothesized model and estimated path coefficients for each proposed relationship in the structural model

SEM is a comprehensive statistical approach to test hypotheses about relations among

observed and latent variables (Hoyle, 1995) Moreover, SEM was defined as a

methodology for representing, estimating, and testing a theoretical network of

(mostly) linear relations between variables (Rigdon, 1998)

CHAPTER 4 DATA ANALYSIS AND RESULTS

Chapter 4 presented the data analysis and findings The first section included data collection, sample characteristics, as well as reliability analysis to improve the

internal consistency of each variable by Cronbach’s alpha Exploratory Factor

Analysis (EFA) was applied to explore the factor structure (how the variables related

and grouped based on intervariable correlation) Continously, Confirmatory Factor

Analysis (CFA) extracted from EFA was examined the measurement models and

Structural Equation Modeling (SEM) was used to test the conceptual model Based on

the data analysis results, the explanation for research findings was discussed

4.1 Data collection

In order to make sure the quantity of respondents enough for the research, this research was distributed 280 questionnaires The objectives of this research aimed to

analysis from view of Vietnamese petroleum industry, questionnaires were delivery

conveniently After collecting the answering, 260 questionnaires were collected (as

similar with the response rate was approximate 92.86%) The questionnaires

collection included 20 eliminated questionnaires due to the same answers for all

asking items as well as the blank items Finally, 240 questionnaires were used as valid

data for this research In comparison with minimum sample size, this value was

satisfactory (see table 4.1)

located 22.1% and the rest of age criteria was from 51 to 60 with 5.4%

In addition, their working duration was more 6 months (95.4%) and they crucially were working full time (97.5%) It also implicated as the common features of

petroleum staffs because of experience demand Most of them were graduated

university showing the high education degree of petroleum staffs (67.5%)

Respondents had the different positions in their job, such as staff (67.8%), team leader

(18.8%), line manager (9.6%) and top manager (3.8%)
