This study concerns the investigation of the social and family influences on the choice and professional practice of nursing, having as objectives to establish a family profile and to identity and to analyse the existing domination/submission attitudes in the professional environment. This study is quanti-qualitative and it uses the historical materialism in the methodological approach. It consists of 117 nurses and 2 instruments, a question form and interview guidelines.

Sexual stereotypes determine the choice and professional practice by women. Men are considered better qualified to have the decision power. The family has influence in the relationship with colleagues and patients. The husband takes part in only of few domestic tasks generating double working time journey work
