The object of this paper concerns the emergence of movements of resistance to RSE. By leaning on three qualitative empirical studies led between 2006 and 2008, it is question to analyse this phenomenon which appears in reaction to the policies of RSE set up by firms. The study reveals three crisis of legitimacy of RSE. The first one, across the example of the implantation of a quality-label "diversity", is the denunciation of the sincerity of theses practices in firms. The second, based on the analysis of equitable trade, holds in the impossibility to consider that ethic values can exist in traditional firms. Finally, the last one reveals that some consumers are in a deep opposition to the concept of RSE and to the logic of sustainable development which underlies it.
