MF 32.5
Not apples and apples. Seniority implies having been there longer. Every year earns a little extra. That is not the case here. It is a change of employment conditions from the case a few years ago, i.e. when new command did not attract a penalty. If it is considered probation, then when the period has successfully been completed the very least is that the with-held pay is refunded. But again, seek legal advice from your 1%. DO NOT assume!
It isn't the first time conditions have changed, either. In 1997 there was no bond for the type rating. In spring 1998 it was 7000, then in summer it was more and by autumn 1998 it was 17000. All for exactly the same thing. Luckily, or perhaps not, this arbitrarely introduced disparity had never to be tested.
