Women now comprise the majority of the higher education workforce; yet they still experience workplace aggression at alarming rates. The purpose of this action research study was to investigate workplace aggression among women colleagues at a small, rural community college. The study also sought to create a more supportive work environment for these women. Cycle 1 consisted of semi-structured interviews with sixteen full-time faculty and staff who identify as women. Data revealed that women had experienced both positive and negative relationships with women colleagues. Further, workplace aggression was linked to status and achievement, social and workplace hierarchies, and insecurity and competition. Based on these findings, and participants' suggestions for interventions, an action step consisting of a five-session professional development workshop was designed, implemented, and evaluated in Cycle 2. The goal was to create the supportive environment that women had identified while talking about positive relationships with women colleagues. Creating such an environment might have implications for increasing self-esteem and confidence and decreasing workplace aggression. The study concluded that group session work of this kind was moderately successful. However, it also revealed that more research is needed on the following: insecurity and confidence, hierarchies among women employees, the lack of safe space for women in the higher education workplace, and the implication these factors may have on workplace aggression. Recommendations for the research site included repeating the workshop series with a different group of participants, considering a volunteer mentorship network, and supporting more formal ways for women to report and mediate workplace aggression issues.
