Surely my workers health is none of my business?

Where the work you want your employees to do creates risks to their health, you have a legal responsibility to do something about this – in the same way as you have for safety at work. When you have done all you can to reduce health risks, but there are still risks to your employees’ health, you may need to put in place a system of occupational health surveillance This provides a system to make sure the controls you have in place are working. The system needs to be managed as you manage safety risks. This means feedback from health surveillance (which can be anonymised) to help you review your risk assessment and controls, and make any changes that are needed.
