Leader-Member Exchange (LMX) model of leadership has suggested that members within the same work team are differentiated in terms of their level of the quality of leader member relationships. However, the differentiation in leader member relationships has not been examined for its possible team-level effects. In this study, the possible impact of this role differentiation on team members' affective reactions was explored. As hypothesized, teams whose members experienced higher level of LMX tended to have higher overall job satisfaction, organizational commitment, and team efficacy. Contrary to expectation, however, the team-level mean on LMX was not related with team-level variability on LMX. Based on these findings, several theoretical and practical Implications are discussed.

The study aims to verify the relationship between leaders' personality traits in leader - member exchange (LMX), and job performance. Hierarchical Regression Analysis was used to examines (a) how leaders' personality traits and LMX affect the influence of social capital on job performance and organizational citizenship behavior; (b) how perceived organization support (POS) can moderate the influences of LMX on social capital, in turn impacting job performance and OCB. Responses are employees in the service industry in Thailand, which consisted of 236 independent samples in 77 groups. Each group included at least one leader and 1-5 followers. The results show that there is a significant relationship between leader's personality traits, LMX and social capital. Leader with the higher level of conscientious, and agreeableness can always create good relations with their followers. The level of LMX are also related to social capital and both of these influence OCB and job performance. The moderating effect of perceived organizational support is also significant that POS can amplify the influence of LMX on social capital. Finally, the research findings show that perceived organizational support is one of the moderating factors in LMX exchanges. Followers perceived organizational support can amplify the influence of LMX on social capital.

This paper investigates the relationships between leader-member exchange(LMX), perceived team efficacy, and organizational citizenship behavior(OCBI, OCBO) in the Korea Post. Also the study investigates the moderator effect of leader integrity and the mediator effect of perceived team efficacy in the relationships between LMX and OCB(OCBI, OCBO). The multiple regression analysis were employed to test the hypotheses. The main finding of this study was as follows: First, LMX had a positive effect on the perceived team efficacy. Second, the perceived team efficacy had a positive impact on OCB(OCBI, OCBO). Third, the perceived team efficacy completely mediated effect on the relationship between LMX and OCBI. Also the perceived team efficacy partially mediated effect on the relationship between LMX and OCBO. Fourth, the positive relationships between LMX and OCB(OCBI, OCBO) were stronger when leader integrity was high rather than low. In particular, this review concludes with implications for future research, limitations of this study, and practical application.

In this study, we examined the impact of empowering leadership on leader-member exchange(LMX), leader trust, and in-role behavior. The role of LMX and leader trust in the relationship between empowering leadership and in-role behavior was verified. We surveyed 289 small and medium enterprises in Yangsan, Ulsan and Gyeongju city. SPSS 18.0 was used for overall descriptive statistics and exploratory factor analysis. AMOS 18.0 was used to conduct confirmatory factor analysis to confirm the validity of the research variables and to conduct a covariance structure analysis to verify the research hypothesis. The result of this study were as follows. First, empowering leadership has a significant effect on LMX, leader trust. Second, empowering leadership did not have a significant effect on in-role behavior. Third, LMX has a significant effect on leader trust and in-role behavior. Fourth, leader trust has a significant influence onin-role behavior. Finally, LMX and leader trust play a mediating role in the relationship between empowering leadership and in-role behavior. Based on the results of this study, it is suggested that the LMX and leader trust should be strengthened through the leader's empowering leadership in order to enhance the employee's in-role behavior.

The objectives of the study were to investigate job burnout and leader-member exchange (LMX) levels as well as to evaluate buffering effects of LMX on burnout among dietitians and chefs at institutional foodservices. Hypotheses were proposed based on the Job Demands-Resources model and LMX theory. The study population consisted of dietitians and chefs who were in charge of managing unit operations in a nationwide contract management company. Positive/negative affectivity, workload, job burnout, and LMX scales that bad been validated in previous research were adopted A total of 552 questionnaires were distributed and 154 responses were returned. Results indicated that respondents' burnout levels were moderate and emotional exhaustion was greater than cynicism. In terms of LMX, the surveyed dietitians and chefs showed higher respect toward their supervisors than loyalty. When positive affectivity and negative affectivity were controlled, workload influenced emotional exhaustion and professional efficacy significantly. With affectivity and workload controlled, however, LMX did not influence any dimensions of burnout. The moderating effect of LMX on the relationship between workload and cynicism was significant. That is, the effect of workload on cynicism was weak if the dietitians and chefs perceived the relationship with their supervisor positively. Based on the findings and literature reviewed, how to mitigate job burnout among foodservice managers is discussed.

The main purpose of this study was to find antecedents of organizational citizenship behavior(OCB) and to investigate the mediating role of leader-member exchange(LMX). This study categorized the factors that influence OCB and LMX into individual(distributive and procedural justice), group(transformational leadership and team empowerment), and organizational levels(complexity). A total of 773 cases were used in this study, which were collected in one of industrial complexes. The research participants were any employees who participated in their work by collaborating with their co-workers. This study found that procedural justice, transformational leadership, and team empowerment had positive influences on OCB, and distributive justice, procedural justice, transformational leadership, team empowerment, and complexity significantly influenced LMX. Moreover, LMX played a mediating role in the relationship between each of the five input variables and OCB.

Purpose - This study aims to measure the influence of the positive psychological capital (PPC) of business workers by using innovative work behavior (IWB) and the influence of Leader-member exchange (LMX) and Member-member exchange (MMX) in this relation and investigating the directional efforts of small and medium company leaders and members. Research Design, Data, and Methodology - This study selects PPC as an integrated superior concept to establish research models and hypotheses of the influence of PPC on IWB, and the influence of LMX and MMX in these relations. Of the questionnaires distributed, 373 valid questionnaires were collected in total. Results - It was confirmed that the PPC of workers has a statistically significant influence on LMX, MMX, and IWB. Moreover, LMX and MMX have similar influence on worker life satisfaction with life satisfaction and innovative work behavior having different dimensions. Conclusion - To enhance IWB, worker PPC is very important as it has significant influence on the relations with leaders. However, it is also notable that positive relations with colleagues did not influence IWB.
