BB,
From this thread and other stuff I remember, if you can prove that the job you are going to is defence related, then the world is your oyster as far as PVR is concerned. I have heard rumours of almost immediate release if your boss says they can cope without you, you can demonstrate the job is defence related and your new employer requests an early release.
As Milarity has advised me, the staff at PMA will help you on this. Give them a call. They are not all bad.
No mention of European Law yet, but I'm sure it applies to us as anyone else......if not adhered to, the RAF lawyers are reluctant to defend any litigation against it. Purely hearsay that one!
