The survey, conducted by questionnaires, consists of 680 full–time employees. The results reveal as follows. First, when the adversity quotient (AQ) of employee is high, the positive relationship between abusive supervision and emotional exhaustion will be less strong. Conversely, when the AQ of employee is low, the positive relationship between abusive supervision and emotional exhaustion will be stronger. Second, the abusive supervision positively influences turnover tendency. Finally, the interaction between abusive supervision and AQ will affect turnover tendency through emotional exhaustion, that is, AQ plays the mediated moderating role. Keywords: abusive supervision, emotional exhaustion, turnover tendency, adversity quotient, mediated moderating role.
