Supervision is an important aspect in the practice of social work. It enhances the service delivery of social workers to clients. Supervision also gives direction to functional workers. A supervisory position in any welfare organization is a managerial position and supervisors are thus managers. It is therefore important to understand the experiences of social work supervisors as first-line managers in a welfare organization. In light of the above, the goal of this study was to explore the experiences of social work supervisors as first-line managers in a welfare organization during and after transition from supervisee to supervisor. The research question arising from the goal of the study was: “What are the experiences of social work supervisors as first-line managers in a welfare organization during and after transition from supervisee to supervisor?” A qualitative, explorative study was conducted, with the following objectives: <ul> <li> To conceptualize social work supervision theoretically, based on available literature.</li> <li> To explore empirically the experiences of social work supervisors as first-line managers, during and after role transition from supervisee to supervisor.</li> <li> To make recommendations regarding the situation of social work supervisors, in order to improve their service rendering.</li> </ul> Nine social work supervisors from the North-Rand Region Service Offices and Institutions of the Department of Social Development formed the sample for the study. After the conclusion of a literature study and pilot study, data collection was based on semistructured interviews with selected supervisors. The main conclusions drawn from the research findings were that social work supervisors go through some difficult experiences when they move from the position of social worker to that of a supervisor. This requires support from their superiors which, according to the study, is currently lacking. The study indicated a need for the generation of more in-depth literature on social work supervision in general. The study was concluded by relevant recommendations to the Department of Social Development in the Gauteng Province.
