It highlights the expansion of these services, driven by coordinated efforts among social partners and emphasizing practical risk assessment and primary prevention. Key developments include the active participation of managers and unions, supported by occupational health personnel. This evolution reflects a growing commitment to protecting workers' health and safety in the region. The findings reflect more coordinated, comprehensive, and robust efforts in Asia-Pacific occupational health services to address risks proactively.
