You are really missing something . One year ago the agency nurse had 134 Euro per hour( I know they don't like paying taxes as all of us ) . The average agency nurse had may be 1000 h on NG and I had more that 4000 .. Was it fair . I don't think so
I didn't say it was fair.
My point is that if you are employed by company A you can't expect the Terms and Conditions to be exactly the same as if you were employed by Company B - even if you both do the same work for company C.
Do you expect all plumbers to quote the same when they fix your pipes?
