What is this about? My understanding is that it gives you the option of serving to 24 years thus increasing your chance of promotion before you leave giving you a better pension (plus the extra two years service), though what I can't figure out is if you come out at 22 and have changed to the new engagement will you still get your full pension? I don't fully get it and I think it's unfair on the younger lads to be given a PD which loosely explains everything without some form of a brief by MCM/Chief Clerks. We had such a brief during the pension change so why not for this. Can someone enlighten me please?
