Ventingan emotionfocused form of coping involving the discharge of negative feelings to othersis common in organizational settings. Venting may benefit the self via the release of negative emotion, or by acting as a catalyst for changes to problematic work situations. Nonetheless, venting might have unintended consequences via its influence on those who are the recipients of venting from others. In light of this idea, we provide a theoretical explanation for how leaders in particular are affected by venting receipt at work. Drawing from the transactional model of stress, we theorize that venting tends to be appraised as a threat, which triggers negative emotion that, in turn, potentiates deviant action tendencies (i.e., interpersonal mistreatment). Yet, our theory suggests that not all leaders necessarily experience venting in the same way. Specifically, leaders with higher need for cognition are less influenced by surfacelevel cues associated with others emotional expressions and find challenging interpersonal situations to be less aversive, thereby attenuating the deleterious effects of receipt of venting. In an experience sampling study of 112 managers across 10 consecutive workdays, we find support for our theoretical model. Altogether, our findings provide insight into the costs incurred when leaders lend an ear to those who vent, which can result in negative downstream consequences.
