Ash, that couldn't be in any worse taste!
Chris don't panic, 4 months is plenty of time to get sorted. There is work out there if you look for it.
I had all this crap last month as there were big changes to the aircraft I was working on (can't disclose any more) and the work now doesn't need doing. (i would've been on 2 wks notice as limited company now...)
Had to look at all options just in case and there is work out there. PM me if you want any links/agencies/contacts etc.
