Being unemployed and having work on-and-off result in diminished self-confidence, increased depression, alcoholism. Stress is the main symptom of the health effects caused by unemployment. It could result in a collapse of the immune system and in a risk of coronary disease or actual onset of it. The stress caused by unemployment can also result in turning to criminal or subcultural groups. Unemployment among young people, especially when long-term, can reinforce bonds with these groups and enhance inclinations to drug addiction. Re-skilling of the unemployed can significantly reduce this health risk.
