My first instinct is that this has got to be a wind up. As it isn't on the NATS forum (who nobody seems to use these days) I must reply here.
If true then it spells the end of Prospect. There is no way they can negotiate any bonus for the poor overworked Heathrow Tower controllers (it surely cannot apply to the guys in TC who do APP for EGLL) without anybody hearing about it until we have a fait accompli.
In fact my second, third and fourth instincts are also that this is a wind up.
Tell me I'm right please!!
