A worker, working for a UK based company is working abroad, during the work he injures himself, nothing too major, but he can not continue his normal role, for the rest of the contract (3days) he returns to the UK where he is still unable to return to work for over 10 days, as he is working out side the UK is this reportable due to the fact he can't now return to work on his return to the UK, 

RIDDOR quotes whilst at work, and is UK legislation, but he now can't return to work on his return to the UK due to an injury at work, thats my quandry.....

We would record the incident any way so the employee is protected, 

Comments please?

David - it might of course be reportable in the country where it happened. That would depend on what, if any, legislation, similar to RIDDOR, that country has.

I can see your quandary. Here is an analogous situation that may help in thinking about it.

Let's say you offer a job to a new starter.  They work their notice for their existing employer and come in for their first day with you.  They tell you that as the result of a recent injury, they are unable to do all of the tasks you might expect from them for the time being, until they have recovered from the injury.  This injury happened at work while they were working for the other employer.

In the new starter scenario, the employee has been injured at work, but not while working for you in the UK, so the new employer is not supposed to make a RIDDOR report.  Making the RIDDOR report, if it was required, was the responsibility of the other employer.

Now in your case, the employee has likewise been injured at work, but not while working for you in the UK, so you are not supposed to make a RIDDOR report.  Making an injury report, if it is required in the country where the injury happened, might in this case be your responsibility but as it happened overseas would not be under RIDDOR but whatever the local system is.

As you have recognised, the important thing is to protect the employee.
