I was recruited from the colonies and took advantage of the option to set aside 10 days of my leave a year for travel home, see the oldies etc...... all in good faith. Eventually the system sent me off to GW1 and then kept me there. In the fullness of time Options for Change came around and I was compulsorily redunded - probably because no-one could locate me (or I wasn't given the piece of paper to return). Simply got a letter in the mail.
Having accumulated around 70 days of (notionally) overseas domiciliary leave yet having been stuck in a work scenario wherein I couldn't avail myself of said leave, I reached my last day of service still asking what was to happen to it.
Of course the final answer was "toughski ****ski", we don't know - so you just miss out. There's no precedent doncha know - and we don't pay in lieu of foregone leave. Why not? Because there's no precedent doncha know. Public servants musta overlooked this scenario.... but we agree that you might have a case.
Because they'd done nothing but fob me off continually until the death-knock. I was ultimately pissed enough to submit a redress (aka "complaint" because redress of grievance is too confronting for it to be accepted in that vernacular). The thusly titled document was returned for me to change it accordingly.
Eight months later, out of the service, after quite a few follow-ups and an eventual appeal to my Local MP I got a one paragraph reply from a one star saying that the matter had been considered and that the original decision was found to have been correct. The failure to address the nature or basic essence of the matter convinced me that they'd not been able to (or hadn't bothered to) locate the "complaint" - and that I'd received a proforma reply.
So, in monetary terms, many thousands of pounds worth of leave down the drain, lots of deception by an unsympathetic system and loads of disgruntlement. On top of all that when I came back here to the UK I got lumbered with a huge poll-tax bill (even though I'd spent all that time in a war-zone).
Getting actual Redress involves a cast-iron iron-clad case with plentiful precedent - or you're just wasting your time. There's no entitlement for Redress against a mishandled Redress.
