Gratitude is a valuable emotion with an array of functional outcomes. Nonetheless, research on gratitude in organizations is limited. In this paper, we develop a multilevel model of gratitude comprised of episodic gratitude at the event level, persistent gratitude at the individual level, and collective gratitude at the organizational level. We then consider the types of human resource initiatives that organizations can develop to cultivate employee gratitude and the contingencies of gratitude's emergence at the individual and organizational levels of analysis. Finally, we elucidate the benefits of gratitude for organizations and their employees. The sum result is a deeper understanding of how gratitude unfolds in organizations and the role that organizations themselves can play in influencing emotions at multiple levels in the workplace.
