Social work being a profession that concentrates on the relationship between individuals and their environment, it seems to be in a good position to help understand handicap by increasing the importance given to environmental factors, that long have been put aside in favor of individual factors. Although, since all disciplinary projects are actualized in a dialogue with their context, it becomes interesting to explore the real expression of the professional identity of social workers employed in rehabilitation settings for people who have physical disabilities, which has been done through a doctoral research. Results demonstrate that, starting with a conception of social work that is partly consistent with the ecological approach, the context influences the way participants take environmental factors into consideration in their diverse roles and tasks. Before bringing the article to a close, these results are discussed in comparison with scientific knowledge on the topic.
