Abstract
Interpersonal conflict adversely impacts organizations, and psychological research suggests a possible antecedent over which organizations may have leverage: employee sleep. However, no known research has examined the link between sleep and conflict in organizations—a context that differs from prior research due to the existence of hierarchy. We set out to examine how organizational hierarchy might influence a potential relationship between sleep and interpersonal conflict in organizations, with several research streams prompting us to posit that individuals experiencing sleep problems would lash out at others, particularly those of lower rank. Thus, we were surprised by the results of our study in the U.S. Army, which showed that soldiers’ sleep problems most strongly predicted conflict with higher-rank individuals. A series of subsequent studies and analyses replicated and clarified this phenomenon, culminating in a plausible explanation: Relationships with higher-rank individuals may involve greater normative constraint and thus require more self-control, but sleep problems compromise people’s self-control. This discovery and explanation hold important theoretical and practical implications such as the idea that sleep problems may loosen the influence of strong organizational norms that individuals typically face pressure to reject (e.g., against conflict with higher-rank colleagues).
