People, especially professionals engaged in work demanding extensive personal commitment, are vulnerable to a complex syndrome characterized by: extreme fatigue, depression, psychosomatic illnesses, substance abuse, apathy, resignation and defensiveness. Symptoms of burnout include feelings of exhaustion, cynicism about one's job and difficulty doing the job successfully.
A 2018 survey found nearly one in four employees feels burned out always or often, with another 44 percent saying they feel burned out "sometimes."
Whilst characteristic of extreme forms of executive stress amongst business executives faced with conditions of rivalry and competition, it appears in a different light in the case of people in the caring professions (health, social services, psychotherapy, relief).
