Workers in cultural industries often express that they are passionate about their work. Passion may be an opportunity to gain more pleasure and well-being at work. However, it may also lead to over-involvement and self-exploitation. Contrary to traditional analyses mainly based on psychological dimensions, this article tries to demonstrate how collective construction of shared and sustainable ideals at work, including some motivating and realistic goals, help workers to manage their passion and successfully combine interest in work and regulation of their involvement in their jobs. The small size of SMACs allow for a precise study of the social regulation of passion. Social regulation is the collective construction of meaning and rules about the way work should be done. This paper is based on a qualitative study (observations and interviews) of three structures in the world of current popular music in order to show the effects of formal and informal organization.
