rate in Companies in Vietnam is growing especially in Sales department of FMCGs companies, there are few studies of the influence of leadership behaviors on both organizational and leader effectiveness That is why FMCG and employees who work in sales sector are mainly focus of this study The objectives of this research to identify relationships between leadership power bases and employee‟s job stress in Companies in Viet Nam A convenience sample is collected from 289 employees from many companies, largely from FMCGs and Sales department The goal was to obtain the influence of leadership power bases used by his or her leaders and the employees‟ job stress to determine if an association exists between these two variables The results indicated that perceived leadership power bases correlate with job stress for employees in these companies The components of the Legitimate power base is positively related to job stress of subordinate, whereas the Expert power, Reward Power and Coercive are related negatively According to the research including on legitimate leadership behaviors, these approaches may lead to high job stress However, using mostly Expert, Reward and Coercive power may result in positive effects such as low stress levels Leadership is at the heart of effective management The research, mainly focusing on companies in Ho Chi Minh City with convenient sampling method to collect data analysis Demographic factors might have affected the results Most of the participants were young with job tenure under three years Moreover, most of the samples chosen came from male gender Finally, there may have been a self-selection bias among the subordinates who participated in this study since participation was voluntary Key words: Leadership, Job stress, power bases Table of contents ACKNOWLEDGEMENTS i ABSTRACT ii CHAPTER 1: INTRODUCTION 1.1 Research background 1.2 Research questions and research objectives 1.3 Research
