Manchester and Scotland are in separate countries! Perth and Melbourne aren't!
Oh please!!!!
You are a whinger!
Technically you might be correct, but it is really just part of the United Kingdom. It takes, what 6 hours, to drive from Manch. to Glasgow. That's how long it took me when I was there in 2000. You speak the same language, use the same currency, pay tax to the same government. Matee, I'd say you're drawing a long bow to keep harping about moving countries when travelling from Manch. to Prestwick.
Melb. to Perth is a 4 hour jet flight. Can't be driven in two days by a single driver. You can't pop across to Melb. for the weekend from Perth like you can drive up to Scotland for the weekend from Manchester.
I think your harping on the "it's in a different country" is petty and churlish. You miss the point. Any move will mean an upheaval for the controllers and their families. The move, if it is really necessary, should be done with the minium impact on the staff involved. What has been done here? And have you involved your union if you think that it could be done better?
