Purpose Frontline service employees are often subjected to customer mistreatment and considerable studies have tested outcomes of customer mistreatment. However, the importance of its antecedents is particularly underestimated. This meta-analytic paper aims to develop an overarching framework that identifies the antecedents of customer mistreatment as well as potential boundary conditions to account for observed variations reported in extant studies. Design/methodology/approach Comprehensive electronic and manual searches were performed to retrieve relevant studies on customer mistreatment, which yielded 125 articles, including 141 independent samples. Altogether, these studies included 40,151 participants. The data were analyzed through random-effect meta-analytic methods in R using the psychmeta package. Findings Three types of antecedents were identified. In particular, regarding employees’ demographic characteristics, age was found to be negatively correlated with customer mistreatment. Employees’ personality traits such as agreeableness, conscientiousness, positive affectivity, emotion regulation ability and self-efficacy were found to be negatively correlated with customer mistreatment, while neuroticism and negative affectivity were positively correlated with customer mistreatment. In terms of contextual factors, perceived social support and service climate were negatively related to customer mistreatment, whereas job demands were positively related to customer mistreatment. Moreover, the power distance culture and types of service industries moderated some relationships. Originality/value This meta-analytic research, drawing upon the perpetrator predation framework, proposed a new and comprehensive framework to explain why customer mistreatment occurs. It not only promoted the advancement of literature on customer mistreatment but also provided effective and targeted guidance for helping frontline service employees reduce such negative experience.
