You are the only tester? Which means only you carry a test kit?
So is there jobs they’re not testing at all? Or just making up values and using your signature which is saved on the software?
How badly do you need this job? Because I can see this causing a bit of a rift.
The NICEIC may not do anything other than telling the company that test sheets x,y,z etc are not valid and need resubmitted… which they’ll do without telling you again, and as far as NIC is concerned, all fine.
Saying that, is there a member on here that is registered with NICEIC and can ask them hypothetically what should happen in this case?
The company needs to send you on every job that’s been fraudulently tested and get you to do it again… however you may never know how many over and above what they might say need doing.
I don’t know if NIC would divulge that information. Ie “give me a list of all test sheets with my signature from this company”
Taking the legal route, and taking it as far as you want to go is really going to cause friction…
Losing your job, and then claiming unfair dismissal on top. Your name could still be being used without your knowledge.
NIC should be your first port of call, but unless you need this job desperately, I’d consult a solicitor.
You will need a strong mental attitude to take it as far as this. It might ruin the company.
