The help of medical and psychological professionals is highly recommended. Since the causes of workplace stress vary greatly, so do the strategies to reduce or prevent it. Where stress in the workplace is caused, for example, by a physical agent, it is best to control it at its source. If the workplace is too loud, control measures to deal with the noise should be implemented where ever possible. If you are experiencing pain from repetitive strain, workstations can be re-designed to reduce repetitive and strenuous movements.
Job design is also an important factor.
Good job design accommodates an employee's mental and physical abilities. In many cases, the origin of the stress is something that cannot be changed immediately. Therefore, finding ways to help maintain good mental health is essential. There are many ways to be proactive in dealing with stress. Share a joke with a co-worker, watch a funny movie at home with some friends, read the comics, and try to see the humour in the situation.
