Law, public policy and mental health in the workplace.

The first part of this article describes regulatory interventions, drawn from different Canadian jurisdictions, designed to reduce worker exposure to psychosocial hazards, including occupational violence, and to protect workers' mental health. It also addresses legislative provisions providing workers' compensation for mental health problems and regulatory provisions supporting the return to work of those who have been absent from work because of work-related mental health problems. The second part of the article, relying on illustrations from case law in which workers' compensation claims for mental health problems have been accepted, examines ways in which law and policy can actually contribute directly or indirectly to behaviours that may lead to increasing illness and disability associated with mental health problems.
