Despite the critical contributions that student affairs professionals make to college students' learning and development and campus operations, mid-level professionals are at risk of leaving the field altogether. The current study investigated the role of sense of belonging in mid-level student affairs professionals' experiences and their turnover intentions through a qualitative, phenomenological analysis. Ten mid-level student affairs professionals from various institutions were interviewed about how they experience belongingness within their work, and how their evaluation of belonging influences their intention to stay at their institution or in the field of student affairs. The results demonstrate that sense of belonging is experienced by mid-level student affairs professionals, but in varied ways, and it is shaped through relationships, being trusted for professional expertise and competence, and feeling supported by others. Salient identities, especially marginalized identities, can shape the experience of belonging as can professional networks outside of institutional experiences. Furthermore, the findings demonstrate that sense of belonging, whether it was experienced or lacking, influenced the intentions of many participants to stay at their institution and in the field of student affairs more broadly. Should colleges and universities be committed to addressing the attrition of mid-level student affairs professionals, they should commit to supporting and cultivating sense of belonging as it does indeed matter. / Policy, Organizational and Leadership Studies
