OHS regulation and enforcement
The regulator’s role in setting and enforcing the adoption of basic standards is fundamentally important to ensuring the health, safety and fair treatment of workers and the productivity of workplaces. Therefore, it’s important for occupational health and safety (OHS) systems to know what will best achieve this. The Institute for Work & Health (IWH) conducts a wide range of research to help labour ministries, workers' compensation boards and other regulatory bodies (and those affected by them) understand where their limited time and money will be most effectively allocated to achieve fewer work-related injuries and illnesses.
