Sorry BALPA, you won't win in the long term on this one. You will bring the airline down with you and you will be out of a job. Tell that to the wife and kids (in public school) when you cant cough up the fees. The bank manager won't give a rats a**** who the hell you think you are. All they are interested is the money.
The days of the glory boys at the front end of the aircraft who think their own s*** doesn't stink, are long gone. An airline has to slim down to survive.
I used to think like you lot and was very militant years ago but soon learnt that they will always get pilots to do your job, make no mistake.
Pilots will never stick together as a group, never and BA know it. Sooner or later, ranks will be broken and a lot of you will be back with your tails between your legs, willing to work for anything, or next to nothing. Then you will be victims of the oldest management trick in the book, divide and rule.
