There is only ever one way to win IA in this modern age, stated in this thread several times and successfully demonstrated by RMT over and over again; the nuclear option that forced BA shareholders to step in.
Unfortunately, BALPA didn't have the balls to pull it off. They pretended to... but nope, nothing there. Some actually defended calling off the 3rd day of strike as a stroke of genius - but as most suspected, it was in fact capitulation. Couldn't even follow through with that.
So now, be prepared for the comeback. The shareholders are demanding a lesson you won't forget, and who's going to stop them?
