The purpose of this study was to investigate dispositional antecedents of hospitality employees’ emotional exhaustion, including self-instability, pessimism, and affect variability, and how employees’ affect variability mediates the relations between self-instability and pessimism and emotional exhaustion. In addition, we explored the moderating role of positive work reflection on the relation between affect variability and emotional exhaustion. A total of 224 frontline employees in 18 four- and five-star hotels in Ecuador responded to surveys about their emotions and work lives. The findings suggest that (a) emotional exhaustion was influenced by affect variability, (b) affect variability mediated the relations between self-instability and pessimism and emotional exhaustion, and (c) the relation between affect variability and emotional exhaustion was weakened by positive work reflection.
