This study used job demands–resources and emotional intelligence theories to test a moderated mediation model explaining work engagement in two independent teacher samples. We hypothesised that emotional intelligence buffers the effect of emotional demands on work engagement through self-appraised stress. Childhood and primary educators (sample 1, N=351) and secondary educators (sample 2, N=344) participated in the study. Although emotional intelligence did not moderate the relationship between emotional demands and self-ap- praised stress, it did buffer the relationship between self-appraised stress and work engagement in both teacher samples. The findings suggest that emotional intelligence has a specific buffering effect affecting intrapersonal and interpersonal processes. We discuss the implications of these findings for efforts to help teachers deal with the detrimental effects of stress on work engagement.
