Talking to a NATS controller mate of mine, he (and his colleagues) think that this whole issue is laughable. As somebody previously mentioned, NATS controllers are on mobile contracts, the inconvenience of moving to the other side of LHR escapes me. If I was inconvenienced in a similar manner and it took me 10 - 15 minutes longer to report for duty, so be it, my company pays
me to work, not travel to work.
Lets not talk about a "bung", how about calling it "Home to duty allowance"?
