Through data obtained in the documents, a tool of work of social workers in Health, we analyze the support networks sought by these professionals to work with the discharge issues, in order to understand how intersectoriality appears transversally during interventions in social discharge, which is still an obstacle to be faced. Thus, the concept of intersectoriality adopted by this research presents itself, being, therefore, much more than joining sectors, is to create a new dynamic for the governmental apparatus, based on territorial and population. In the expanded conception of Health, intersectoriality appears as a proposal for a new way of working, governing and building public policies.
