Sparkyt,
Nats aren't taking previous employees at the station that was constantly desperate,and one of the only airports showing growth.
HIAL seem to be looking for people for the Isles,but that is ADI and APP ratings required,no removal costs and a life style choice.
I would say that there aren't jobs out there at the moment.One reason could be the number of ex mil people who have preceded you.Also the economic situation,and Air passenger duty/tax.
If you asked units you would find they are short of validations,but on paper are fully staffed.Perhaps the Birmingham contract situation might cause a little musical chairs,but I have my doubts it will last.
IMHO
