While the live performance sector is increasingly attractive, especially for young professionals, taking into account the health of professionals has long been underestimated. As such, recent studies highlight a significant and growing malaise among artists. This project aims to identify the specific factors in the construction of the health of performing artists (and more specifically in the field of music, theater and dance) according to three levels (institutional, collective and individual) with a view to contribute to the improvement of prevention approaches, likely to be appropriated by players in the sector, in all their diversity. We seek to understand the links between the work activity of performing artists, their working conditions and the possible impacts on their mental, physical and social health. Our research problem is formalized as follows: in what way and how the joint consideration of the institutional, collective and individual levels of the health of performing artists is a lever for the prevention of occupational risks? We are thus seeking to identify the obstacles and resources to health to enable the construction and implementation of innovative systems where primary prevention plays its full role. Given the specificities of the live performance sector - its specific forms of employment, the conditions of exercise, the particularity of the relationship of subordination, its attractiveness, in particular for younger generations and its consequences on health... - the latter seems to us particularly relevant to study in order to identify the ways and means of improving the health of artists, based not only on the challenges facing the entertainment world but also on its history and culture. Added to this is that artistic creation is the fruit of a decision-making trio (administrative, technical and artistic) as well as the result of the action of two different populations that are the intermittent and the permanent of the show on the same event. To investigate this environment, qualitative methods will be used to question the players in the sector, observe companies and experiment with innovative participatory mechanisms to put the issue of health at the heart of the collectives. Several companies with different profiles are ready to open their doors to us in order to support them over several months. To carry out this JCJC research project, Elsa Laneyrie, MCF in work psychology and ergonomics will collaborate with researchers from five laboratories, an essential institutional partner and companies. Over 42 months, several studies will be deployed in order to identify the systems implemented, the knowledge already mastered by the actors, the individual and collective strategies deployed by the artists in order to build their own health. A report will be produced in parallel in order to keep track and present the actions undertaken within the companies. The conclusions will be such as to highlight the prevention strategies to be deployed to make health a central issue for the development of the sector and the profession of artist. We want to mobilize the sector and all stakeholders to identify sustainable resources to build and prevent health. More broadly, we hope that the conclusions of this work will make it possible to reduce professional risks, strengthen job retention, develop social dialogue, equip institutions to intervene as closely as possible to the needs of intermittent workers.
