Constantly exposing individuals to high levels of stress can have a lot of health consequences. This is mainly caused by an individual not being correctly prepared, or due to the lack of appropriate support or skills required, in order to cope with requests or demands. This leads to growing problems not being solved soon enough, and the person ends up in a state of high emotional tension. All internal bodily systems become exhausted, which can result in illness and diseases. Due to problems coping with difficult or new tasks at work, self-esteem is lowered, which can adversely affect both the employee and the employer, which in turn affects the entire workplace. For that reason, the aim of this article is to communicate the research results of the professional burnout phenomenon, based on the analysis of selected literature concerning the subject.
