According to research by the Trades Union Congress (TUC), more than 500,000 workers suffer from repetitive strain injury (RSI) and 5.4m working days were lost last year due to the illness.
The illness, which includes symptoms of chronic joint pain and immobility, renders six people unable to work each day. However, it can be treated with workplace adjustments and physiotherapy if caught early.
TUC general secretary John Monks said: "Union safety reps can now use the HSE's risk filter to help managers get a grip on the risks of RSI and prevent suffering, job loss and poverty for thousands of people. We want to see partnership in action, preventing RSI."
