Here's a few reflections from 15yrs in aviation.
Baggage handlers have always been militant. always have been, always will be...no change there then.
Ground/passenger handling staff, by the very nature of the people who do that job (they like dealing with people) are generally very tolerant...I say again, something must have really hacked them off, for them to do this. Maybe they've decided that time for talking has gone.
I have never known ground staff not go the extra mile...and let's be honest, no-one risk's their livelyhood (and by extension their mortgages, families etc) without very good reason.
nurjio...why was 'dispatchers' post "daft"? because it disagreed with you?, well, I disagree with yours. I think you should read anti-ice's post...seems to me he has some idea of what is going on.
I work for another large charter airline, and I sympathise with the BA staff. Have you thought that maybe the staff think they have no other choice?
