When I was a wannabe I moved for my first job. I moved for my second too. I almost moved for my third. Now I have umpteen thousand hours on decent types I don't want to move. I wouldn't move anywhere unless there was sufficient incentive to do so. Most of those guys in BFS are only headin to EZY for a bit more money on their doorstep..can't fault that. Many of them are already on Jets on their doorstep. To be told 2 weeks before you start at EZY that you won't be on your doorstep despite the fact your contract states you will, patently sucks.
For the majority it will be too late to retract their notice. The EZY captains of tomorrow are the seriously pissed off first officers of today. Not a good way to run a Flt Ops department.
