The purpose of this study was to examine how a leader's organizational citizenship behavior (OCB) affects subordinates' interpersonal citizenship behavior (ICB) and job stress levels. A leader's OCB involves taking-charge behavior, loyal boosterism, and the industry. We hypothesized that leader-member exchange (LMX) would mediate the relationship between leader's OCB and subordinates' ICB and job stress level. We tested the model using a sample of 293 employees from different organizations from September 2019 until November 2019. We conducted confirmatory factor analyses of the variables and analyzed the data by using structural equation modeling. We also conducted a CFA to assess the fit of a three-factor model for the leader's OCB items. Empirical findings show that LMX fully mediated the effect of leader's OCB on employees' ICB and job stress level. Leader's OCB had a positive effect on LMX. Moreover, LMX had a positive effect on employees' ICB but had a negative effect on job stress. We found support for our hypotheses that leader's OCB is positively related to ICB but negatively related to job stress, and this relationship is mediated by LMX. We discuss limitations, implications for practice, and future research.

This paper aims to figure out an effect of aged sports instructors' emotional intelligence on leader-member exchange (LMX) and organizational citizenship behavior and to improve a work environment by developing members' emotional intelligence. To achieve this goal, it handed out a survey to 282 elderly sports instructors from five sports centers and elderly sports centers located in Seoul, Gyeonggi, and Chonan in Chungcheongnam-do and collected it from them. After then, it conducted a relationship analysis and multiple regression analysis and showed the following findings. First, it suggested that emotional intelligence of elderly sports instructors significantly affected leader-member exchange (LMX) positively. Next, it turned out that the emotional intelligence had a significant positive influence on organizational citizenship behavior. Last, it found that leader-member exchange (LMX) of the instructors did significantly impact on the organizational citizenship behavior positively. Therefore, as a result, it is very important that the paper demonstrated the emotional intelligence of the aged sports instructors significantly contributed to the advancement of leader-member exchange (LMX) and organizational citizenship behavior, and the development of members' emotional intelligence had a positive effect on the effectiveness of organizations.

The purpose of this study is to examine the effect of leader-member exchange(LMX) on employee's affective commitment and continuance commitment focusing on the mediating role of job stress. On the basis of theoretical linkages between the constructs, a conceptual model and hypotheses were established. The sample included 482 employees. Structural equation modeling(SEM) was employed to test the hypothesized relationships in the conceptual model. This study shows that the proposed model is reasonably fit to the actual data. Empirical results indicate that LMX has a negative impact on employee's job stress, has a positive impact on employees' affective commitment and continuance commitment. Employees' job stress has partially mediated effect on the relationship between LMX and employees' affective commitment, but has not mediated effect on the relationship between LMX and employees' continuance commitment.

We hypothesize work jealousy can moderate the relationship between leader-member exchange (LMX) and two different work behaviors, counterproductive work behavior(CWB) and organizational citizenship behavior (OCB). The results supported our hypotheses and found an interaction between LMX and work jealousy such that the relationship between LMX and CWB is negative when jealousy is higher but not when jealousy is lower. We did not find an interaction between LMX and work jealousy on OCB, however. We test our hypotheses in a service organizational sample consisting of one hundred thirty-nine. Managerial implications and directors for future research are discussed.

The purpose of this study is to identify the effects of perceptions of organizational politics(i.e., POPs) and leader-member exchange(i.e., LMX) on the perceived work performance. Also, this paper investigates the moderating effect of LMX on the relationship between POPs and work performance. Particularly, this study is to expand on prior research by investigating the three-way interaction effect of LMX and self-efficacy. The summary of results based on a sample of 280 employees who were working in various organizations in KOREA is following. First, POPs were not significantly related to perceived work performance. Second, LMX was positively and significantly related to perceived work performance. Third, LMX did not moderate the negative relationship between POPs and perceived work performance. Finally, our results showed that for individuals with a high level of self-efficacy, LMX moderates the negative relationship between POPs and perceived work performance. That is, for individuals with a high level of self-efficacy, POPs were positively related to work performance under high LMX(in-group), but were negatively related to work performance under low LMX(out-group). Theoretical and practical implications of our findings as well as directions for future research are provided.
