This study will discuss the contradictions that involve the implementation of the Multiprofessional Residency in Health (RMS) program within the Unified Health System (SUS). The RMS in the official speech proposes to strengthen the SUS, however, it is inserted in an environment of dismantling health policy. In this work we will make a historical recovery of the contradictions that involve RMS and present results of a study carried out in a multiprofessional health residence in the city of Rio de Janeiro. It is concluded that the RMS is inserted in a terrain of contradictions against the disputes within it for its purpose. Nowadays, while we live the political incentive for vocational training for the SUS, via the RMS, which has been put as a strategy for its reorganization in a direction more aligned with the constitutional precepts, we have noticed, however, the tendency of RMS To be included in a strategic framework for structuring the public service network by offering a precarious workforce for health professionals and submitted to a health model that prioritizes private excellence. Thus, RMS can reinforce the simplification of resources and the weakening of the articulation between the service and the academy, reproducing the logic is recurrent in the formation. Finally, we observed difficulties in ensuring the interlocution between training, management, health care and political participation. It is urgent to strengthen RMS as a resistance strategy of the movements in defense of the SUS in the conception of Sanitary Reform.
