The formation of networks as a strategy for professional action is a broadly advocated theme within the framework of social policies, which have been historically organized in sectors and need to have their actions reorganized in view of the increasingly complex social demands. Networking is understood as a resource to confront the social question and its consequences, and as a tool for effecting proposals for professional intervention. Occupational therapy can use the creation and/or strengthening of social networks as processes that seek to ensure greater autonomy and social insertion to individuals or groups who are experiencing processes of rupture in their lives. This study aimed to investigate the strategy of forming intersectoral networks between the services that comprise social policies in the municipality of Campinas, state of São Paulo, Brazil, as a possible support tool focusing on the work of occupational therapists. As a method, 13 district coordinators from the social assistance, education and health areas were interviewed and a questionnaire was applied to 17 of the 36 occupational therapists (47%) working in the municipal network. In addition, two institutional networks were observed for four months. Finally, nine occupational therapists participated in a face-to-face meeting to discuss their experience and role in networks. Here, the data from the questionnaires and the group with the professionals are analyzed. In conclusion, considering the centrality of social (re)insertion as an objective of the occupational therapists, in addition to characteristics such as availability and flexibility, the promotion of intersectoral networks is a part of this work; however, this cannot be considered a specific or exclusive professional action.
