Laurence, Based on the information you provided, your post reads to me: A member of staff recently sustained an injury at work - they were signed off for 7 days! RIDDOR - Yes! You're clearly phased by the gap, however, could that be down to bruising, swelling, pain etc. not so apparent at the immediate time of the injury? Wait for it...

Yes. IMO. RIDDOR doesn't say that its 3 days directly after an incident. Andy

Defo RIDDOR reportable as had one where staff member sustained injury to hand but remained at work. A week or so past and pain continued so went to GP who dressed wound. Another week or so past and still really painful so back to GP who sent person to local hospital who said there had been damage sustained to the tendon and surgery was required to rectify. Remained at work till appointment date and only then was the person sighed off (a few months now since the accident). I contacted HSE when person told me she had attended hospital initially and was told reportable if signed off post operation (which the person was).
