Academic literature has recognized teaching as a particularly stressful occupation, specifically, the research confirmed the central role of emotional dissonance in the experience of emotional exhaustion. Albeit previous studies confirm the existence of circular dynamics involving job demands and individual’s well-being, studies focusing on the long-term relationships between job demands, need for recovery, and emotional exhaustion are still lacking. Therefore, the aim of the present study was to explore how emotional dissonance, need for recovery, and emotional exhaustion are related over time. By using the general framework of the health impairment process of the Job Demands-Resources model, these paths were investigated by means of a three-wave longitudinal design (n = 107 schoolteachers). Results of structural equation modeling analyses generally supported our hypotheses. Specifically, it was found that the model with reciprocal relationships between emotional dissonance and exhaustion on the one hand, and between need for recovery and exhaustion on the other, exhibited the best fit with the data.
