This study tested a moderated mediation model whether employees with higher equity sensitivity (i.e., the entitled) would strengthen the indirect paths from leader-member exchange differentiation (LMXD) to knowledge sharing (KSB) via procedural and interactional justice compared to lower equity sensitivity (i.e., the benevolent). To test our hypotheses, a survey was conducted on 300 South Korean employees working with colleagues under the same direct supervisor. The results implicated that LMXD was negatively related to KSB. Moreover, the relationships of LMXD with procedural and interactional justice were stronger for entitled employees than benevolent employees. Furthermore, equity sensitivity strengthened the indirect path from LMXD to KSB via interactional justice in the parallel mediation model where both procedural and interactional justice were simultaneously input, whereas equity sensitivity did not change the indirect path from LMXD to KSB via procedural justice. However, when procedural and interactional justice were input separately, equity sensitivity also strengthened the indirect path from LMXD to KSB via procedural justice. Based on these research findings, implications of this study were discussed along with suggestions for future research.
