Workplace-based supervision in human service organizations (HSOs) is essential for promoting frontline worker well-being and enhancing service quality. However, limited research has explored the preparation, support, and well-being of HSO supervisors, all of which may influence the quality of supervision they provide. This cross-sectional survey of HSO supervisors in Ontario, Canada (N = 75), examined their preparation, support, and well-being (i.e., using the Professional Quality of Life Health measure). Social workers made up the largest professional group represented in the study. Findings from descriptive statistics and inductive qualitative content analysis reveal that while many supervisors received training and their own supervision, they also felt unprepared for the complex role demands of their positions, with most receiving no onboarding. Participants provided considerations for HSO onboarding, additional training, and their own supervision needs. Though most supervisors reported moderate well-being with few cases of burnout, this study highlights the need for robust supervisory support, enhanced onboarding, and continuous supervisory training in HSOs.
