resources, human resource is the most important asset which makes organization successful Without good manpower, organization could not develop their business Retaining the talents in organization is an emergent challenge that every organization must consider According to Berry (1997), organization must improve job satisfaction of employees to be successful Robbins & Judge (2007) found that the effective organization usually had more satisfied employees Moreover, satisfied employees are more likely productive In short, improving employees’ satisfaction is an essential solution for an organization to be successful The practice of leadership has existed for thousands of years and research efforts have been undertaken to better understand leadership in organizations for well over 50 years (Bass, 1990) Leaders and leadership play an important role in organizations in the way that effective leaders are related to successful team work, high morale, and effective performance; and on the contrary, ineffective leaders are related to job dissatisfaction, low commitment, and ineffective performance (Avolio & Bass, 2002; Bass, 1998; 1999; Collins, 2001a, 2001b; Day, Zaccaro, & Halpin, 2004) We also have seen some big scandals in ethical leadership in the world as well as in Vietnam In Vietnam, according to Thuc (2011), some big organizations such as Hàng Hải Đông Đô, Masan Group, Quoc Cuong Gia Lai announced to investors that they made large profit, but actually, they lost a lot In international level, we also know the big decrease of ethical leadership of the top managers of WorldCom, Enron, General Motors and Lehman Brothers in U.S Together with new societal challenge such as terrorism, aging society, and environmental pollution… these destroy the trust of investors In reality, according to National Leadership Index 2009, 63% of Americans not trust what business leaders say and 83% believe that business leaders work to merely their benefit or a small group with special interests, not society overall In the difficult situation, there is an urgent need of the positive and more genuine leadership (Avolio & Gardner, 2005) Reliability, integrity and authenticity are the essential characteristics of the business leaders in this situation (Blausten, 2009) In the light of current developments in global business, a new construct emerged: authentic leadership Authentic leadership refers to the extent to which an individual exhibits a pattern of openness and clarity in his or her behavior towards others by sharing the necessary information to make decisions, accepting other’s inputs, and disclosing his or her personal values, motives and sentiments in a manner that enables followers to more accurately assess the competence and morality of the leader’s actions Business practitioners are calling for leaders who lead with purpose, values, and integrity, leaders who build enduring organizations, motivate their employees to provide customer service, and create long-term value for shareholder 1.2 Research objectives: In this study, the author examines the effects of authentic leadership behaviors on followers’ job satisfaction while also taking into account possible moderating roles of self-efficacy and optimism to the relationship authentic leadership and job satisfaction Accordingly, the study aims at answering the research questions: “How does authentic leadership influence follower job satisfaction?” and “what are the moderating roles of self-efficacy and optimism between authentic leadership and job satisfaction?” In order to answer to this research question, the following four sub-questions are addressed in this research: What is the relationship between authentic leadership and follower job satisfaction? How does self-efficacy play a moderating role in the relationship between authentic leadership and job satisfaction? How does optimism play a moderating role in the relationship between authentic leadership and job satisfaction? Is job satisfaction level different between male and female? 1.3 Research scope and approach: First, this study is conducted in Ho Chi Minh City, the biggest city in Vietnam Second, the research includes into the analysis those respondents who have been working with their leaders for at least months to ensure that followers have enough time to observe and to be influenced by their leaders’ leadership behaviors Third, the research only focuses on employees who are graduated from highschool or higher This choice of population and sample frame makes the study feasible (given time and resource limitation) by facilitating online survey method and helps address the research questions in the simplest way possible Forth, this study considers self-efficacy and optimism as the moderating variables Self-efficacy, optimism are two of components of psychological capital However, other components of psychological capital which are resilience and hope are not considered in this study Fifth, the study is conducted in main phases: pilot study (comprising of subphases) and main study The purpose of the pilot study is to check the contents and to examine the measurement scales Then the main study is conducted to confirm the measurement scales, to test the hypotheses and to confirm the research model 1.4 Research structure The structure of study includes chapters as following: Chapter 1: Introduction will provide the research background, research objectives, as well as research scope and approach 67 D Cuối cùng, xin Anh (Chị) cho biết thông tin cá nhân: Giới tính Anh (Chị):
