As a social being, human beings make their work an inherent part of the process of humanising the place where they live. However, because workers dedicate a large part of their time to the work environment, they also become subject to various types of situations that can have a negative or positive impact on their physical and mental health. For Oliveira J. et al. (2010, p.636), following the lessons of Dejours, Dessors and Desriaux, work is a dimension of satisfaction, balance and promotion of the individual's personal well-being, but it can also become a factor of sadness and illness. The consequence of this for the worker's health, whether the occupation is a source of pleasure or pain, will depend on whether they are able to carry out a balanced activity, a source of personal development, or an exhausting occupation, the source of malaise, stress and occupational illnesses.
