This study investigates the connection between employees’ experience of time-related work stress and their job performance, with a particular focus on the mediating role of their propensity to engage in negative gossip and the moderating role of their collectivistic orientation. The results based on multisource, three-wave data from employees, their peers, and supervisors in Pakistani organizations show that an important reason that time-related work stress might diminish job performance is that employees expend significant energy discussing their negative evaluations of other organizational members with peers, possibly as a way to protect their self-esteem resources. This mediating role of gossip is also invigorated by employees’ collectivistic orientation. For organizations, this study identifies a key mechanism – informal conversations with peers about the flaws of others in the organization – by which time-related stress prevents employees from allocating sufficient energy to completing their job tasks, and it reveals that this process is more likely among collectivistic employees.
