Abstract
The researches that specifically analyse the working conditions of teachers are few in the ergonomic literature. Our research relates more specifically to teachers of physical education and sports in french context of college. The research project described here includes both a quantitative exploratory survey (218 respondents) and qualitative case studies (interviews and observation), using the general framework of Activity Ergonomics. The results of this exploratory work tend to emphasize the importance of collective and organizational dimensions in the experience of teachers’ physical education and sports. Specifically, in a perceived context of degradation of working conditions and accumulation of constraints, the collective and local ability to negotiate the various constraints on the activity appears to be a protective factor. This power to act, these margin of manoeuvre could be a relevant topic for future research.
