This article analyses the sports offer proposed to employees by large private sector corporations with Mauss’ theory of the gift. It questions how and why employees perceive these sport offers as gifts made by the company. As symbols of the opposition between cooperation and competition, sports conciliate performance and health in the workplace. What is the effect of such offers on employees? What are the counter-gifts that are called for? This article argues that sport offers encourages employees to invest themselves in the workplace by modifying the perception of the corporation through the introduction of forms of gift-based primary sociality in an environment structured on impersonal functional relations and market objectives.
