Little things matter: a daily diary study of the within-person relationship between workplace incivility and work-related rumination.

Workplace incivility is a low-intensity, counterproductive work behavior associated with negative health outcomes and organizational consequences (e.g., turnover intention). In the present study, I used a daily diary design to investigate the short-term within-person effects of workplace incivility on work-related rumination. Time pressure was included in the present study to underline the importance of workplace incivility for off-work ruminative thoughts beyond the known effects of a stressful workday. Additionally, I propose mood at the end of the workday as a mediator for the proposed relationships. The results of my study corroborate the existence of the daily within-person and the more stable weekly between-person effect of workplace incivility on off-work ruminative thoughts. These results suggest that the experience of short-term and fluctuating workplace incivility has an impact on off-work ruminative thinking even when controlling for the known effects of time pressure. With regard to my proposed mediational effect, my hypothesis was not confirmed. In an additional analysis, however, mediation was confirmed when time pressure was excluded from the model. Further, the within-person relationship between time pressure and work-related rumination was mediated by mood.
