In a 10 year study published in the British Journal of Medical Psychology, people who were not able to manage their stress effectively had a 40 percent higher death rate than those who were "unstressed."
When people feel powerless, they're more likely to resort to anger and violence. We've seen this happen in schools and with people who have lost their jobs who have channeled their fear and anger toward other people. Violence is both a cause and a consequence of employee stress. In organizations today, managers and employees have to deal more with potential violence. This in turn causes increased workplace stress.
