ABSTRACT

This study investigates the relationship between knowledge hiding and extra-role performance, while considering the mediating role of emotional exhaustion and moderating role of political skill. Results based on multi-source, two-wave time-lagged data from 428 pair respondents (i.e. employees and their supervisors) show that employees’ persistent exposure to knowledge hiding episodes reduces their extra-role performance, because they become emotionally exhausted. Employees’ political skills buffer this harmful effect of knowledge hiding on emotional exhaustion though, such that this effect is mitigated when political skills are high. For organisations, this study accordingly identifies a key mechanism through which knowledge hiding can undermine the voluntary behaviours at workplace; and this mechanism is less forceful for employees with high political skills. Several practical implications are also elaborated.

摘要

本研究探讨了知识隐藏与角色外表现之间的关系，同时考虑了情绪耗竭的中介作用和政治技能的调节作用。基于来自 428 对受访者（即员工及其主管）的多源、两波时间滞后数据的结果表明，员工持续暴露于知识隐藏事件会降低他们的角色外表现，因为他们变得情绪疲惫。不过，员工的政治技能缓冲了知识隐藏对情绪衰竭的有害影响，因此当政治技能高时，这种影响会得到缓解。对于组织而言，本研究相应地确定了一个关键机制，通过该机制隐藏知识可以破坏工作场所的自愿行为；而这种机制对具有高政治技能的员工的效力较小。还详细阐述了一些实际意义。
