A friend who is in the same position recently told me about some of the things he is got going on in the back of all this regarding legal advice so standby for some updates shortly.
He also brough out a very good point that the Pay Warrant stated that having completed 9 yrs service you went onto P2 middle after 3 years. If you then got Ac Comd at the 4 1/2 yr point (year and half later) you remained on P2 middle until 4 years had been completed (marking time as P1 intial not as much as P2 middle). Therefore this reflects the 7 year point at which you would have moved onto P1 middle (7-11) for 4 years and then P1 higher at the 11 year point and enhanced at the 15 year point. This is what they have now said the regulations state so therefore some of the dates that DAAvn sent out are actually incorrect IAW the pay warrant that has been mis read for the last x amount of years. Interesting thoughts and work it out for yourselves so there is at least something we can get back.
