I'm sorry to hear you are having to go forth with a FPEB but sometimes it's the best thing to do to get out of it what will be best for your family. I wish you the best of luck!
After my board was completed and I accepted the findings, I have right at 3 months before my final day. Luckily I had enough leave, House/job hunting + Terminal, to take up that whole 3 month period. It was nice to be able to relax for a bit and also take care of the move and find a new home during that time.
I was told by my admin dept. that the average time frame for separation is 1 to 3 months once a board is completed and the separation package is sent up. I don't know how they determine the date for retirement/separation but you'd think they would allow everyone at least the 3 month period.
What are your hopes for the FPEB?
