I'm sure my wages have dropped and only realised today. When I started at my school 4 years ago, on M5, my wages matched the union guidelines. I'm on M6 now and my wages went up but checking today I realise that I am payed significantly less than M6 as defined by Union scales. How do I find out what I should be paid? Do I have to ask my headteacher...or the bursar...or call HR?
