Lets be quite clear, BALPA did not 'roll over'.
Flt Ops set a cost savings target, BALPA consulted with the membership as to how best to achieve that saving. Members voted to accept a small pay cut and increase productivity to reach those targets.
We could have just said, we'll all work harder and you can make the bottom 100 pilots redundant. But that's not how we like to do things, hence the pay cut to save pilot jobs.
CC on the other hand lost 1003 of their colleagues through the new onboard complements. Luckily enough wanted to go voluntarily.
