INTRODUCTION This research studies factors of psychological empowerment which impacts on job satisfaction of employees in two industries, namely service and manufacturing This chapter provides an overview of research including research background, research problem, research objectives, scope of study, and significance of the study In this chapter, an overall structure of the research is also suggested 1.1 Background of the study Nowadays, in an evolving environment, organizations are working under highly competitive context In order to survive in such a tough environment, organizations try to seek out their competitive advantages The most critical challenges they have to face are the need to increase productivity, enhance organizational capabilities, expand into global markets, develop and implement new technologies…, etc (Burke and Cooper, 2005) Employee is regarded as a back bone of an organization that performs critical tasks for the survival of the organization With the needs of changing for the growing nowadays, organizations have forced not only to develop the quality of product of service but also the organization capabilities, especially their employee through their performance However, the impact of human resources on operational systems has often been overlooked (Boudreau et al 2003) An empowered and committed workforce is generally claimed to be essential for the effective functioning of modern organizations (Bowen et al, 1992; Sparrowe, 1995; Kirkman et al, 1999) In organizations, empowerment means delegating responsibilities to employees with complete confidence and trust so as to assume a more active and responsible role This strengthens their sense of effectiveness as well as by sharing power, information and the responsibility to manage their own work as much as possible There is a broad context of empowerment in many dimensions as well as perspectives Some approach by individual to proactive work orientation by increasing employee’s performance and some can be viewed as managerial practices TIEU LUAN MOI download : skknchat@gmail.com to improve employee autonomy and responsibility Researchers such as Burke (1986) and Kanter (1977) have also defined empowerment in terms of job structure the transfer of power or authority or job support structures such as the sharing of resources and information (Blau and Alba, 1982; Hardy and Leiba O’Sullivan, 1998) In these studies, empowerment is viewed from the perspective of the leader’s role in empowering employees Many others studies view empowerment as individual task motivation (Conger and Kanungo, 1988; Thomas and Velthouse, 1990) or motivation from person and environment fit relationship (Zimmerman, 1990) while Randolph (1995) asserts that employee empowerment is a transfer of power from the employer to the employees Most of the literature which reviewed many perspective of empowerment concludes that an empowered workforce will lead their organization to achieve a competitive advantage Employee empowerment increases productivity by increasing employee pride, self- respect and self- worth In recent studies, one of the dominant classifications of employee empowerment accepted by many researchers is given by Spreitzer (1995) The author defines psychological empowerment as “the intrinsic motivation manifested in meaning, competence, self-determination, and impact, in which an employee feels able to shape his role in work and context” The concept is employed in a number of studies such as Avolio et al (2004), Corsun et al (1999), Carless (2004) and Jha et al (2008) According to Hofstede and Bond (1984), “power distance is defined as the extent in which less powerful members of organization accept that power is distributed unequally” In Vietnam, power distance is influenced by the Confucianism, in which the ordering relationships are in the hierarchical fashion and the behaviors in society are based on these orders, Gudykunst (2000) Taking more responsibility and authority always goes along with additional benefits in Vietnam Vietnamese are quite indecisive in delegating power Being a social republic state and high power distance, Vietnam is the country in which the power is not distributed equally and regarded as the basic fact in society In organizations, close supervision, fear of disagreement with supervisors, lack of trust among co-workers, TIEU LUAN MOI download : skknchat@gmail.com McCaig, B., & Pavcnik, N (2013) Moving out of agriculture: structural change in Vietnam (No w19616)
