Gawd, you do love banging on about our unions and the like don't you I have no idea who you are, except that you make
no contribution to the debate here, yet somehow manage to surface every time the subject comes up and have a shot at the writer.
Are you by any chance somebody I know from elsewhere, but posting under a duplicate ID?
The stuff about "unions" has been pretty well aired at another forum a while ago, where a bunch of ATCOs vigorously demolished various proposals, on the usual basis of circular arguments based on regulations and ... wait for it ... working practices.
Union rules will always be wrapped up with the job description; if they were significantly different the whole lot would be out on strike
