Flying Shortly
I agree with some of what you say but I would not want to turn this forum into a union bashing political bun fight. Some unions have had a policy of reasonable conduct over the past twenty to thirty years (some might say too reasonable at times) while others have not.
Inside BA the pilot & engineering unions have always been very moderate and understand the dire situation that the airline is in and are acting accordingly. However you don't have to go much further than the cabin crew forum to find people who just don't see what is going on in the real world.
I fear that that a lot of very skilled people are going to be out of work because of the very short sighted actions of the very well paid (semi-skilled) cabin crew.
