Résumé : The purpose of this study is to contribute to understanding the role of emotional regulation strategies in the relationship between emotional dissonance and well-being at work. The study was conducted on a sample of 559 nurses from two Algerian hospitals. The results indicate that emotional dissonance has a negative relationship with work engagement and job satisfaction. Attentional deployment and expressive suppression play a mediating role in this relationship. Emotional work can be understood as an important mechanism in the relationship between dissonance/well-being at work.
