For data collection, the Psychosocial Well-Being Scale and the Maslach Burnout Inventory, associated with the Utrech Work Engagement Scale, were used. In general, positive evaluations for psychosocial well-being and engagement, as well as, lack of characteristics of Burnoutpredominated. The overall average in the Psychosocial Well-Being Scale was 4.93, with a standard deviation of 1.04. Men who work for one to five years presented higher values in the effectiveness dimension.
