Would anyone be kind enough to explain the rules concerning an individual (SAC) who is occupying a Cpl post (long term, 3 years), therefore A/Cpl and PSF have turned round and said that it will be Unpaid!? Is this correct? It's just that having read AP 3376 Vol 1 Pt 1 Ch 7 i seem to be under the impression that it should be Paid!??
