Drawing on research interviews with thirteen self-identifying working-class professional services employees in Russell Group institutions, this article attempts to develop a nuanced approach to understanding institutional cultures in UK universities, through the relationships within these establishments. Throughout the study, the tensions between working-class professional services or administrative staff and their counterparts working on academic trajectories became clear. Often highly qualified themselves, the participants in this study describe feelings relating to inadequacy and often negative attitudes proliferated towards them by academic staff. These relationships are framed within the perspective of three themes: academic hierarchies and superior academic value, treatment of staff, and language codes and patterns. In contrast, the participants in this sample often describe their relationships with their networks in professional services as highly positive, developmental, and enriching. This study focused on working-class professional services staff specifically. In the field of working-class research, professional services staff from working-class backgrounds have currently been largely omitted from research, which tends to focus on working-class students and working-class academics. Not all professional services staff identify as working-class, but due to this deficit of evidence in the research field, it is this group in particular that this paper focuses on. The findings in this paper suggest that the relationships these professional services staff have with academics are often fraught, difficult to manage, and at times, derogatory in their nature. This finding comes at the juxtaposition of the wider inclusion agenda UK universities pursue.
