In this chapter, we examine employee prosocial rule breaking as a response to organizations’ unfair treatment of customers. Drawing on the deontic perspective and research on third-party reactions to unfairness, we suggest employees engage in customer-directed prosocial rule breaking when they believe their organizations’ policies treat customers unfairly. Additionally, we consider employee, customer, and situational characteristics that enhance or inhibit the relationship between employees’ perceptions of organizational policy unfairness and customer-directed prosocial rule breaking.
