Job
Work-related stress is common among men and women who have demanding jobs and work long hours. Workers also tend to be more stressed during poor economic times when they worry about layoffs or a reduction in hours.
Self-Generated
Stress also can be caused by a person's inner thinking. For example, unrealistic expectations and perfectionism can make events in which a person did not realize his ideals even more stressful. Pessimism and negative self-talk also can cause stress.
