Workplace bullying is a widespread phenomenon within Higher Education Institutions (HEIs). Employee tendency to remain silent is one of the most common reactions to workplace bullying. Yet, employee silence in the context of workplace bullying is poorly studied. Building on the Conservation of Resources Theory (COR) and the Learned Helplessness Theory (LHT), this study investigated employee reluctance to take action when witnessing workplace bullying (employee silence). The sample comprised 560 employees working in 20 HEIs in Ireland. Respondents filled out a survey measuring employee silence, victimisation, and team psychological safety. Results showed a negative association between team psychological safety and employee silence, indicating a reluctance to report bullying among respondents with low levels of team psychological safety. In line with the COR and the LHT, a positive association was found between victimisation and employee silence. The paper concludes with a discussion of possible actions for bullying prevention in HEIs.
