Positive organizational scholarship has led to a growing interest in the critical role of positive emotions for the lives of both workers and organizations. We review and integrate the different perspectives on positive emotions (i.e., positive valence, positive emotion regulation strategies, and positive adaptive function) and the four main mechanisms (i.e., cognition, affect, behavior, and physiology) that lead to positive organizational outcomes. There is growing evidence that positive emotions influence variables vital for workplace success such as positive beliefs, creativity, work engagement, positive coping, health, teamwork and collaboration, customer satisfaction, leadership, and performance. We additionally review dynamic features of positive emotions (i.e., intraindividual variability, reactivity, inertia, cycles, feedback loops) and their relation to psychological and work outcomes. Finally, we discuss additional questions and future directions for consideration.
