Although cyber incivility (i.e., an interpersonal workplace stressor displayed through uncivil behaviors manifested in online working communication) occurs every day in the workplace, we know little about how it influences employees’ task performance at daily level, nor why and when this influence occurs. To address these limitations, we theorized and tested a model that links cyber incivility to task performance via negative affect and sleep quality at daily level and a cross-level boundary condition at the person level (i.e., self-leadership). Multilevel modeling results based on data collected from 112 full-time employees with 866 observations suggest that daily cyber incivility has a time-lagged effect on task performance of the following day after controlling for task performance the same day. This intrapersonal effect can be explained by the induced negative affect of the following workday but not sleep quality of the previous night. In addition, the relationship between cyber incivility and negative affect and the indirect effect of cyber incivility on task performance via negative affect were weaker among employees with high rather than low self-leadership.

尽管网络不文明行为（即通过在线工作交流中表现出来的不文明行为表现出来的人际工作场所压力源）每天都在工作场所发生，但我们对它如何影响员工日常工作绩效，以及这种影响发生的原因和时间知之甚少。为了解决这些限制，我们建立了理论并测试了一个模型，该模型通过日常层面的负面影响和睡眠质量以及个人层面的跨层面边界条件（即自我领导）将网络不文明行为与任务绩效联系起来。基于从 112 名全职员工收集的数据和 866 次观察的多层次建模结果表明，在控制当天的任务绩效后，日常网络不文明行为对第二天的任务绩效有时间滞后影响。这种人际效应可以用下一个工作日诱发的负面影响来解释，而不是前一天晚上的睡眠质量。此外，网络不文明行为与消极情绪之间的关系以及网络不文明行为通过消极情绪对任务绩效的间接影响在自我领导力高而不是低的员工中更弱。
