The effects of burnout on client service provision, organizational health, and individual well-being are increasingly a focus of social work research, particularly against the societal backdrop of the post-COVID-19 era. Children and their families rely on school social workers (SSWs) to meet increasingly pressing and common mental health needs. However, burnout may jeopardize not only SSWs' well-being, but also their collective ability to serve this vulnerable population. The current study captures SSW perspectives on burnout related to the following themes: SSW-administrator dynamics; role conflict and lack of role definition; presence of trauma in caseload; systemic challenges (including the subthemes of unrealistic workload, the desire for more interprofessional collaboration and social work-specific supervision, and limited resources); and the effects of the COVID-19 pandemic. Using these perspectives as a guide, policy recommendations are made to enhance interprofessional collaboration, clarify roles and responsibilities, and safeguard SSWs as "first responders" for children's mental health.
