I think the backlash against the BALPA reps is more to do with the realisation that many of them aren't sharing the pain of the many recent changes to Bidline.
Added to that is the suspicion that some are making serious amounts of money in overtime through "clash and protect". I don't doubt that some of the reps are in the job for the right reasons,however, I think it is recognised that some are merely the other side of the coin to our flight ops managers, and have more in common with them than they do the line pilots.
Personally, I only see this all ending in tears, whether a company falling apart under the strain, or a big smoking hole in the ground.
