Outcasts and saboteurs: Intervention strategies to reduce the negative effects of social exclusion on team outcomes.

The experience of social exclusion in the workplace adversely impacts employees' well-being, job satisfaction, and productivity, and no one quite knows what to do about it. In this report, we describe the development and testing of three ostracism interventions, designed to help people cope with the negative effects of being excluded by one's team. Across five studies, participants were assigned to a virtual ball toss game where they were either included or excluded by their teammates. Afterwards, they were given a task where they could earn money for themselves, for their entire team, or for an unrelated group (charity). Excluded participants worked less hard for their teams (even when this meant sacrificing their own earnings). This sabotage effect was specific, meaning that excluded individuals worked less hard on behalf of their teams, but not when they worked for themselves or for charity. We devised three intervention strategies-perspective, mentorship, and empowerment-to combat the negative effects of ostracism on people's willingness to work for their teams. These interventions were successful; each increased people's persistence in a team-based reward task, and in some cases, even raised the outcomes of excluded teammates to levels observed in included teammates. The effectiveness of these interventions also replicated successfully, using preregistered hypotheses, methods, and analyses. These studies add novel insights to a variety of fields that have examined the consequences of social exclusion, including social psychology, organizational behavior, and management science.
