Abstract
The main aim of this empirical study is to explore the mediation role of the leader-member exchange (LMX) between organizational justice and job performance in several tobacco companies in Pakistan. Two models are represented in this study, the first showing the influence of the dimensions of organizational justice on job performance, and the second the influence of organizational justice on job performance with the mediating role of LMX. The data was collected from 290 employees working within several tobacco companies in Pakistan. The results of the statistical analysis found that the dimensions of organizational justice had both a direct and indirect stronger effect on job performance. It was proved empirically that LMX plays a vital role not only on organizational justice but also on employee performance. This is one of the first studies to empirically examine the mediating role of LMX in the relationship between the dimensions of organizational justice on job performance in tobacco companies in Pakistan. The study highlights the importance of job performance theory when designing strategies to promote performance.
