Summary Burnout has become an increasingly prevalent condition, especially affecting professionals in direct contact with clients. Human service workers (HSWs) have quite emotionally taxing jobs supporting vulnerable groups. In developing a close relationship with the communities they work with, it could be possible that community-related variables have an impact on HSWs’ burnout. We aim to analyze the prevalence of burnout in a sample of HSWs from Portugal and the role of community resilience as a predictor of their burnout, as well as explore if their subjective well-being and community attachment could explain the relationship between community resilience and burnout, during the COVID-19 pandemic. Data were collected through an online questionnaire between August 2020 and January 2021 ( N = 598). Findings Results indicate that HSWs presented medium to low levels of burnout, although 8.9% presented high levels. Those who reported lower levels of burnout perceived higher community resilience and had much higher well-being and community attachment. Findings point to community resilience having a significant direct effect on burnout and also an indirect effect, which was explained by subjective well-being and community attachment. Applications Results seem to suggest that this sample's low-medium levels of burnout could be linked to the benefit of experiencing high community attachment and working in communities with high resilience, which consequently impacted their well-being and burnout. This highlights the crucial role of the work context in professionals’ mental health, showing that a broader context needs to be considered in professional mental health promotion programs.
