<p>While bullying and incivility are established concerns in academic workplaces, less is known about how department chair leadership and the culture surrounding the chair role relate to faculty experiences of mistreatment. This study examines whether chair-role culture and chair/supervisory bullying are associated with faculty reports of incivility/negative workplace behavior. A total of 193 survey responses were recorded; 25 responses were incomplete, leaving 168 participants with usable demographic/descriptive data. The focal regression model required complete data on the chair-culture indicators, the chair/supervisory bullying indicator, and the six-item incivility/negative workplace behavior index, resulting in a complete-case analytic sample of 92. The broader study examined structural and cultural features of academic departments, while this focal analysis examined whether negative workplace behavior was associated with chair-role culture and whether the chair/supervisory role was identified as the source of bullying or mistreatment. Regression findings indicated that both chair/supervisory bullying and chair-role culture were significantly associated with the dependent variable. Participants who identified the chair/supervisory role as a source of bullying or mistreatment, and those who perceived the chair role as less clear, more informal, and more dependent on the individual occupying the role than on formal policy, reported higher negative workplace behavior scores. Findings highlight the relevance of chair accountability, role clarity, and transparent departmental processes for understanding how faculty experience incivility and negative workplace behavior in academic departments.</p>
