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

本研究调查了知识隐藏与角色外绩效之间的关系，同时考虑了情绪衰竭的中介作用和政治技巧的调节作用。基于来自428对受访者（即员工及其上司）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，因为他们变得精疲力尽。员工的政治技巧可以缓冲隐藏在情绪疲惫中的知识的有害影响，因此，当政治技巧很高时，这种影响就会减轻。因此，对于组织而言，这项研究确定了一种关键机制，通过这种机制，知识隐藏可以破坏工作场所的自愿行为。这种机制对具有较高政治技巧的员工的作用较小。还阐述了一些实际含义。
