Drawing from social exchange theory, we developed a dual-path model of employees' reactions to episodic help received from colleagues. Through a diary study, using data collected from 127 full-time employees working in a large Chinese bank, we tested this model, revealing that receiving episodic help from colleagues is positively related to the help receivers' gratitude and ego depletion. Through these two ambivalent psychological states, help receivers were found to simultaneously engage in more organizational citizenship behaviors and deviance behaviors on a daily basis. These empirical findings contribute to research that adopts a target-centric perspective in examining the consequences of helping behavior in the workplace.
