A little advice if possible..

Hey Bav, I don't know how your system works but if you may be called to work through the job center again, I'd go ahead and get a doctor's note that will let them know what type work they can't put you on in the future.

Yep  

Oh they know, it was already done, but neither me or the job centre knew I'd be sent to a waste transfer station. Its on there now though. Initially on my record it said cannot work with food due to P, to her credit she even called the company and said that she hadn't written it on there because she never thought in a million years i'd be sent somewhere like that.

Ok, that's good Here in the U.S. if they had discovered you shouldn't have been working there for medical reasons they would have moved you quickly somewhere else (or simply told you that you could stay home) and begged for mercy as they'd be afraid of a lawsuit. But at least you shouldn't have to worry now about job placements.
