...so it must be down to poor BA management.
A great deal at BA can be put down to poor management, which is in part why we all find ourselves in this situation now. Had BA management been firmer with BASSA in the past, the cabin crew may not have found themselves in this particular predicament.
The trouble is this though. The management (pick your department) have been economical with the truth so frequently in the past that no one believes them any more. Frankly, the response of the Ostrich Brigade on here is no real surprise.
The fact remains that if changes aren't made, BA will not be around much longer. Don't ask me, ask Price Waterhouse Cooper. The one guarantee I will make is that WW does not want to go down in history as the last CEO of British Airways and he will do anything he needs to do to prevent that. If it means imposing an arrangement on the cabin crew, he will. You've been warned and you have the rest of June to sort something out. Would you like some sort of say in the changes or not? That's up to you to decide but changes will be made. Rest assured.
BA have a fighting fund but it is not limitless. A strike will probably kill the airline, which shouldn't be a problem for most of you as that seems to be what you want and you'll just waltz into an equally well paying job the following day. Won't you?
Grow up.
