Make sure that you don't get any ideas of grandeur. You were a Sgt when you left - acting doesn't count for anything at that stage (although I wait to be proved wrong) - so you could only come back in as a Sgt as the highest rank.

I'm shure you are as aware of Glasgow's odd approach to the more important things in life, however if you let them know you are ready to go ASAP, and you can get your receiving unit (if you know it) to chivvy things along, we could be talking weeks.
I was also wondering if anyone knew what the pension situation wud be. I rejoin the new system and the 'pension clock' starts again at 12 years??? Do i have to pay back my resttlement grant? or is that sneakly deducted from my pension i wouls hope not. Also i take it that LSSA goes to zero and i would lose seniority?
