This thesis analyzes the effects of a psychiatric reform on everyday practices of the technicians and nursing auxiliaries work, coming from consideration of work as a possible space of feelings production and the reform, which means a permanent construction of knowing, by practicing, at the same time it leads, inserting ,in this praxis, a dialectics. This study helps to create listening groups about the work of this category, achieving recognition and rescue of its speaking, making exchanges, facing a feeling of discomfort at work, creating possibilities of subjectivation. Referring to the nursing formation and the impasses of the profession, this thesis visualizes the necessity of changes in this theoretical-technical field, proving that the technicians and the auxiliaries do not have any space for their knowing, built in practice (and it can only be this way),and that this category is considered invisible, in most of discussions, about the reform, being fundamental when it happens.
