A theoretical reflection is developed, featuring the characteristics of the Nursing work force in the rooming-in units. A focus is given, along a leading line, to the importance those workers have in caring for the families of newborn children in hospital facilities. The reference basis, adopted as the argumentative development of the text, centers on previous studies and authors covering the work process in Nursing, as well as on the understanding of nursing as a social and historical practice. Reflection is initially developed along considerations of the organization and division of work in health and in nursing. This study also points out the formal and legal origin of Brazilian nursing workers, in order to characterize this work force specifically in the work process carried out by nursing agents of different levels in rooming-in systems at the maternity facilities. The conclusion reached, showed that the work developed in these units requires from the nursing professionals proper qualification to assist the newborn, the puerpera and also the family. They must also demonstrate theoretical/technical command to operate those instruments (means) which are not usually available in the majority of health services.
