Firstly, did she record the accident in your accident book at work (as you are required to record any accidents or near-misses)? Secondly, was the company negligent, did she slip of spillage, or fall over soemthing that shouldn't be there? This is exactly what you pay your employer's liability insurance for, and if the organisation was negligent then she is entirely entitled to make a claim against the company. I used to work in liability insurance and I can't say after all these years whether it would make a difference to future premiums, but your girlfriend would have to prove negligence in order for the claim to succeed. You must record the accident (it's an obligation under the Health & Safety at Work Act). It's not a question of keeping one side or the other happy, it's a case of legal liability. If she makes a claim she must write a letter and you pass it to your insurance company, they handle it. You can't ignore it if she wants to pursue it, but a pay-out is by no means guaranteed at this stage. Just make sure it's fully documented, just in case.
