This article proposes to understand, from the perspective of Complexity Theory, and through critical theoretical reflection, the precarization of work as a reality in the Brazilian public health work market, and its influence on the results of a public policy based on the theoretical/practical paradigm of Territorial Psychosocial Care. It outlines a possibility of problematizing the central theme, through the principles: systemic, hologrammatic, retroactive circle, recursive, autonomy/independence, dialogic, and the reintroduction of knowledge in all knowledge, proposed by Edgar Morin, in view of the discussions and studies carried out by the Life and Work Research Group on the precariousness of work and mental health in a concrete field. This reflection is intended to be a source of recognition for actors on the real causes of precariousness, which derive from the way in which health work is exploited, which is closely related to the application of neoliberal prescriptions in authoritarian bureaucratic states located on the periphery of dependent capitalism. The reflection allowed the understanding of the whole and the parts that constitute the problem, recognizing the real causes of precariousness, which blame mental health workers, in the face of unhealthy conditions, working hours, and insecurity about social rights and labor rights.
