Employee creativity is critical for an organization's innovativeness and survival in today's competitive business environment. As such, scholars have devoted significant attention to the predictors of employee creativity, seeking to understand how to best increase employees' creative output. However, employee creativity may not always translate into organizational innovation and performance. In fact, employee creativity may result in various outcomes for creative individuals, their coworkers, teams, and organizations. While there have been several integrative reviews on the antecedents of creativity, an in-depth review of the outcomes of creativity is still needed to gain a holistic understanding of the benefits and costs of employee creativity and identify fruitful areas for future research. Thus, we aim to provide a comprehensive multilevel examination of the theories, methods, and creativity-related constructs used to examine the outcomes of creativity. We also provide several theoretical and empirical opportunities for future research. This review may provide managers with knowledge of the pros and cons of employee creativity, enabling them to make informed decisions on how to better manage employee creativity.
