Black staff working at predominately white institutions (PWIs) of higher education experience systemic workplace racism undergirded by higher education's deep connections to and reproduction of White supremacy and antiblackness. This phenomenological qualitative research study entails a literature review with historical, conceptual, and empirical studies to show the connection between the origination of White supremacy, its role within the U.S. PWIs, and the resultant impacts on Black PWI staff. The literature review includes a background to understand the origin of current Black PWI staff racialized experiences in their workplace. There is a body of research on Black faculty experiences in their higher education workplaces, but less is known about Black PWI staff experiences. The literature review contains research studies documenting the experiences of Black faculty and staff due to the dearth of research focused on the workplace experiences of Black PWI staff. To address this research gap, the researcher investigated the experiences of 10 Black PWI staff. The Black PWI staff answered four research questions related to the following areas: (a) how they experienced systemic racism in their PWI workplace, (b) how they understand systemic racism, (c) how their mental and physical health are impacted by regular exposure to systemic racism in their workplace, and (d) how they thrive despite systemic racism in the workplace. The findings indicated nine areas of agreement with the literature reviewed on Black PWI faculty experiences with systemic workplace racism. This study contributes to the existing literature by increasing research on Black PWI staff, acknowledging K-12 systems as PWIs, showing the importance of proximity to Blackness for Black PWI staff, and demonstrating the profound impact of fictive kin relationships in the PWI workplace for Black staff. The research recommendations address the need for PWI employers to improve the workplace environment and for Black PWI staff to thrive within the systemically racist PWI workplace.
