LFFC
Why would my pension be any of their business?
Sadly this one of those huge gotchas and is, ISTR, a Treasury rule. God forbid that we might allow someone to earn their pension, leave and then come back in on similar pay + their pension.
Only applies if your pension is a military one, because of course you have to be ex-military to be FTRS. I think that you have to retire at senior Wg Cdr or Gp Capt rank not to lose any of your pension. If you retire as Flt Lt/Sqn Ldr and I think junior Wg Cdr then you will lose an element of your pension if you want to come back as FTRS.
Wrong? Absolutely. But sadly one of those stupid rules that means that FTRS QFI is no longer attractive to many = extreme shortage of FTRS QFIs even around those traditional recruiting grounds of York and Lincoln!!!
