This paper proposes a reflection on the precariousness of work in social assistance in the city of Caxias - RJ, taking into account the various forms of integration of workers in welfare policy, with prominent reflections of a neoliberal logic. This debate focuses on one of the research axes of the Integrated Center for Studies and Research in Security and Social Assistance (NIEPSAS), and as the locus of social assistance policy of the Duque de Caxias city. The approach elements of the study fall within the changing landscape of the Brazilian social assistance, post-implementation of the 1988 Federal Constitution, the Organic Law of Social Assistance (1993) and the National Assistance Policy (2004). Through this study we try to reflect on ways of hiring workers crowded in the Social Assistance; the physical structure of service of public facilities available to service in accordance with the provisions of the Ministry of Social Development and Fight against Hunger (MDS); the relationship between demand and service capacity; professional practice conditions to which workers are exposed which, among other things, demarcate the specifics of assistance policy in the Baixada Fluminense.
