ISO 45003 is the international guidance on managing psychosocial risk within an occupational health and safety management system. It is guidance rather than a certifiable standard. You are not audited against it directly. You use it to show that your ISO 45001 system takes psychological health as seriously as physical.
It works in every country, whether or not local law requires psychosocial risk to be managed. The ILO made a safe and healthy working environment a fundamental right at work in 2022, and the WHO recommends acting on psychosocial risks. ISO 45003 is how you show you have.
Switching to the ISO lens re-presents the same responses under the standard's own structure, so what you hand an auditor uses their vocabulary rather than ours.
Workload and pace, hours and scheduling, job control, role clarity, job security, change management.
Relationships, supervision and support, recognition, civility and respect, and the behaviours that erode them.
The conditions and exposures that carry psychological as well as physical risk.
A group operating across several countries is answerable to different law in each of them. ISO 45003 is the framing most multinationals can put in front of every jurisdiction at once. Because it sits beside ISO 45001, it is usually the structure your existing safety management system already understands.
