Digital platforms and tech giants have led to a rapid shift in values and traditional ways of working. Although "diligence" has long been essential for work success and promotion, em-ployees in modern companies are reluctant to blindly follow this attitude. Many well-known Western companies, such as Facebook and Google, see fun in the workplace as conducive to productivity and creative behavior. We investigated the associations of fun at work with expe-rienced fun, employees' creative behavior, managers' support for fun, and trust in a Chinese context using different scales. Discriminant validity was confirmed by confirmatory factor anal-ysis. A total of 508 workers from Taiwan and mainland China participated in the study and completed questionnaires. A key finding was that fun at work was positively related to em-ployees' creative behavior. In addition, moderators of managerial support for fun and trust be-tween the workplace and experienced fun were confirmed. These results can serve as a reference for Chinese managers who want to encourage creative behaviors and prevent negative behaviors in the workplace. In practice, results suggest that fun should be allowed more in the workplace because it could contribute to positive outcomes. However, managers should create a workplace that is fun, allows for creativity, and at the same time leads to high productivity.
