This book provides a comprehensive review of the state-of-the-art on the adaptive and maladaptive functions of humor. Humor is inescapable in our daily interactions - also at the work place. Affiliative, self-enhancing, self-deprecating and aggressive humor can all occur at work and have unique and sometimes ambiguous effects. The volume presents humor research on five important workplace topics: teams, leadership, negotiation, learning, and health. It combines and integrates research from a range of fields, including work and organizational psychology, social psychology, communication, linguistics and sociology. In highlighting research gaps and stating future research questions, the book provides a sufficient starting point for further research on humor in relation to the aforementioned topics. For practitioners, recommendations are provided specific to each area.
