(Huselid, MA 1995), (Guest 1997), (D Hartog and RM Verburg 2004), (Singh K 2004), human resource practices have important influence on the performance of the business By studying factors contributing to the effective human resource management, it proves that preceived organizational support (POS) takes an important position in this area POS contributes to increase employees’ performance (POS) to help organizations reach their objectives The behavioral outcomes of POS mentioned herewith include increases, decrease in role and Job performance The study of effective Human resource (HR) management, specifically relationship between perceived organizational support (POS) and job performance also measures of man-power resource to achieve set targets of organizations; help managers with solutions to encourage and motivate employees to work effectively in conditions of tight labour market, where changing knowledge management practices and global convergence of technology has redefined the nature of work, and in the context of limited talent resources in manpower market By studying the impact of Perceived Organizational Support on Job Performance it has been seen that there are mediation factors also contribute to establishing relation between Perceived Organizational Support on Job Performance Following Kahn (1990) people employ and express themselves physically, cognitively, emotionally and mentally during role performances” By This reason this study also analyzes related mediation factors to support to the relation of Perceived Organizational Support on Job Performance As we know that there is little theory or empirical observation accounts for the role of perceived organizational support, engagement as a means through which organizations can create competitive advantage In particular, not many researches examine the role of engagement as mechanism that links employee characteristic and organizational factors to job performance This can be explained why the situation is the same in Viet Nam, not many research and specific study on the Perceived Organizational Support and Job Performance Also, almost no research and no specific study on the Perceived Organizational Support and Job Performance in Viet Nam The majority of organizations in Viet Nam has not yet invested interest and improves their system of human resource management in this specific area Due to this reason, the topic we choose for our thesis is studying “The Impact of Perceived Organizational Support on Job Performance, the Mediation of Job Engagement - A Study of Commercial Banks in Viet Nam By this study, we will expect to find out solution on how to improve manpower resource management in commercial banks in Viet Nam, especially solutions relating to factors affecting the impact of Perceived Organizational Support on Job Performance, the Mediation role of Job Engagement in Commercial Banks in Viet Nam For the result, the study is expected to explain how bank community should respond to challenges of human resource so as to get satisfactory staff’s performance and satisfactory business outcome through the factors of Perceived Organizational Support and Job Engagement 1.2 Purpose of the research The purpose of this research is to study the impact of Perceived Organizational Support on Job Performance and related mediation factors to the relation of POS–Job Performance (JB) in commercial banks in Viet Nam, specifically: - Relationship between perceived organizational support and job performance in banks in Viet Nam - Investigating mediation factors that are affecting relationship between perceived organizational support and job performance in banks in Viet Nam - Evaluating affect of find factors that are positively affecting job performance in banks in Viet Nam; find factors that are positively affecting relationship between perceived organizational support and job performance in banks in Viet Nam - Offer measures to improve the impact of perceived organizational support to job performance in banks in Viet Nam, help banks to improve business performance and enhance their ability to attract, motivating, satisfying and keep qualified employees, encourage the employee to work in an effective way 1.3 Questions of the research With the above mentioned background, there arise question required to be studied so as to have solution as follows: What is the common relationship between perceived organizational support and job performance in commercial banks in Viet Nam? Which factors can be applied to improve the impact of perceived organizational support and job performance in commercial banks in Viet Nam, which are key factors? Can the improvement of relation of perceived organizational support and job performance promote and develop competitive advantage and performance outcome of commercial bank in Viet Nam? 1.4 Scope of the research Study subjects: staffs and managers of commercial banks in Vietnam Since HR Management is a very broad research theme, this research only focuses on studying scientific basis to help managers understand the factors that relationship between perceived organizational support and job performance so that they can implement these tools in banks This research is limited in the scope of the Impact of Perceived Organizational Support on Job Performance, related Mediation of Job Engagement (PE) in commercial banks in Viet Nam 1.5 Framework of the study Introduction Research problem Research questions Research objectives Literature review Hypothesis Empirical model Data collection Descriptive statistic Data analysis Conclusion, recommendation and limitation CHAPTER 2: LITERATURE REVIEW Chapter is to review theories of Perceived Organizational Support on Job Performance and related mediation factors to the relation of POS–Job Performance (JB) including Physical engagement (PE), Emotional engagement (EE), Cognitive engagement (CE), and Job performance (JB) This Chapter also presents related theories, antecedent researches; hypothesis development and proposed research model Most of the research in Organizational behavior has been concerned with three attitudes: job satisfaction, job involvement, and organizational commitment Other attitudes are also attracting attention from the researchers, including perceived organizational support (POS) and employee engagement In our research we concentrate in studying the relation of organizational support, employee engagement and job performance in the context of commercial bank in Viet Nam: 2.1 Perceived organizational Support (POS): As one of definition, POS is the degree to which employees believe that their organization values their contributions and cares about their well-being (Eisenberger, Huntington & Sowa, 1986; Rhoades & Eisenberger, 2002) POS is generally thought to be the organization’s contribution to a positive reciprocity dynamic with employees, as employees tend to perform better to pay back POS (Rhoades & Eisenberger, 2002) Research on perceived organizational support observed if managers are concerned with their employees’ commitment to the organization, employees are focused on the organization’s commitment to them For employees, the organization serves as an important source of socioemotional resources, such as respect and caring; and tangible benefits, such as wages and medical benefits Being regarded highly by the organization helps to meet employees’ needs for approval, esteem, and affiliation Positive valuation by the organization also provides an indication that increased effort will be noted and rewarded Employees therefore take an active interest in the regard with which they are well taken care of by their employer Organizational support theory (OST: Eisenberger, Huntington, Hutchinson, & Sowa, 1986; Rhoades & Eisenberger, 2002; Shore & Shore, 1995) indicated that in order to meet socioemotional needs and to assess the benefits of increased work effort, employees form a general perception concerning the extent to which the organization values their contributions and cares about their well-being Such perceived organizational support (POS) would increase employees’ felt obligation to help the organization reach its objectives, their affective commitment to the organization, and their expectation that improved performance would be rewarded Behavioral outcomes of POS would include increases in in-role and extra-role performance and decreases unexpected outcome and behaviors from employees Although there were relatively few studies of POS until the mid 1990’s, research on the topic has developed in the last few years Rhoades and Eisenberger’s (2002) metaanalysis covered some 70 POS studies carried out through 1999, and over 300 studies 69 Reliability Statistics Cronbach's Alpha N of Items 921 Item Statistics Mean Std
