LMX, Context Perceptions, and Performance: An Uncertainty Management Perspective
研究领导-成员交换如何调节员工对组织公平和政治的感知对工作绩效的影响，发现低质量交换关系下这些感知对绩效影响更强，对管理者和学者理解员工反应有参考价值。
This study investigates the role of leader—member exchange in moderating the effects of perceptions of organizational justice and politics on job performance. In contrast to previous research, which has relied on social exchange theory to explain these relationships, the current study uses uncertainty management theory to propose that relationships between employee perceptions of the context (e.g., perceptions of organizational politics, procedural justice, and distributive justice) and performance are stronger for employees who have lower quality leader—member exchange relationships with their supervisors. Analysis of data from a sample of 157 government employees and their supervisors provided partial support for the three hypothesized interactions and indicated that leaders play an important role in determining how employees respond to their perceptions of politics and justice and that neither social exchange theory nor uncertainty management theory fully explained our results. Theoretical and practical implications of our findings as well as directions for future research are provided.
