Studies have shown that the expression of positive emotion is an important element in relationship intimacy and a robust predictor of relationship satisfaction. Although the positive influence of displaying authentic emotions toward intimate partners is well documented, research has largely overlooked the association between authentic displays of either positive or negative emotions between employees and managers and the impact of these displays on emotional exhaustion. In a sample of 331 employees, the quality of the employee–manager relationship fully mediated the association between authentic positive emotional displays and emotional exhaustion; in contrast, the association between authentic negative emotional displays and emotional exhaustion was only partially mediated. The findings contribute to a better understanding of the role of employee emotional displays in shaping leader–member interactions, and work-related outcomes.
