Under the National Occupational Health and Safety Strategy 2002-2012, work-related mental disorders was identified as one of the eight occupational disease or disorder categories to be addressed over the life of the national strategy.
Worldwide there has been an increase in work-related mental disorders, affecting all industries and professions. The major causative mechanism, recorded in the National Data set, is mental stress. Mental stress is coded as caused by work pressure, harassment, workplace or occupational violence, exposure to a traumatic event, suicide or attempted suicide and other mental stress factors.
As such, this report confines itself to discussion on work-related mental disorders associated with mental stress, which in itself has been identified as the causative mechanism in work-related mental disorders: stress, anxiety, depression, nervous breakdown, and effects of witnessing traumatic events.
