The folk on '05 pension is an interesting one because it is/was designed to retain personnel until their 55th birthday and has been very effective at doing so. This of course means that if you choose to leave before you are 55 through whichever course of action (pvr/ngr) you would have been financially disadvantaged. (Notwithstanding the leave in your final year for tax purposes if you intend to continue working scam).
To 'sack' people presently employed in a 'pic' that does not get subsequently disestablished is forbidden under civil law and more often these days, civil law is being adhered to by the military. I know that HMG believe themselves to have a get-out-clause for all walks of lifes mysteries but EDP for the rest of your life is somewhat differant to a time critical PA pension. I guess the punchline is that some people may find themselves in an unwanted position that could be legally challenged, unless Manning box very clever at a targeted audience. Of course the closure of any base makes an entire workforce vulnerable even within civilian guidelines.
