Background: Mental well-being has become an increasing concern in Canadian workplaces. However, there is a lack of studies that focus on the well-being of leaders. This is particularly evident in the community social services sector where leaders may face high mental and emotional demands on a daily basis.

Purpose: The purpose of this study was to examine whether psychological fatigue mediate the relationship between job demands and work outcomes, including affective commitment and turnover intention. Furthermore, this study looked at whether workplace supports, including supports from one’s organization, supervisor, and colleagues, moderate the mediated relationship between psychological fatigue and work outcomes.
