This study examined the effects of leader-member exchange (LMX) on organizational commitment and helping behavior, the effect of organizational commitment on helping behavior, and the mediating effects of helping behavior on the relationship between LMX and job performance and the relationship between organizational commitment and job performance. To do this, the study hypothesized as follows: Hypothesis 1. LMX will be positively related to organizational commitment.Hypothesis 2. LMX will be positively related to helping behavior.Hypothesis 3. Organizational commitment will be positively related to helping behavior.Hypothesis 4. Organizational commitment will be positively related to job performance.Hypothesis 5. Helping behavior will be positively related to job performance.Hypothesis 6. Helping behavior will mediate the relationship between LMX and job performance. Hypothesis 7. Helping behavior will mediate the relationship between organizational commitment and job performance. Data were collected from 247 employees in Korean distribution companies. Results indicated that LMX was positively related to organizational commitment and helping behavior. Results also indicated that organizational commitment had a positive effect on helping behavior, but had not significant effect on job performance. Especially, helping behavior fully mediated the relationship between LMX and job performance and the relationship between organizational commitment and job performance, respectively. From this, we discussed implications for job performance in theory and in practice.
