This paper investigates how employees' experience of workplace incivility may steer them away from idea championing, with a special focus on the mediating role of their desire to quit their jobs and the moderating role of their dispositional self-control. Data collected from employees who work in a large retail organization reveal that an important reason that exposure to rude workplace behaviors reduces employees' propensity to champion innovative ideas is that they make concrete plans to leave. This mediating effect is mitigated when employees are equipped with high levels of self-control though. For organizations, this study accordingly pinpoints desires to seek alternative employment as a critical factor by which irritations about resource-draining incivility may escalate into a reluctance to add to organizational effectiveness through dedicated championing efforts. It also indicates how this escalation can be avoided, namely, by ensuring employees have access to pertinent personal resources.
