It's not my company here but people would do well to remember that 96% of BA cabin crew voted for a strike. Far fewer than that believed that they would actually have to go on strike and when the big day loomed the number who voted yes but were actually either going to work or call in sick became quite apparent. In the end they walked away with some nil cost face savers for the union, lots of talk about 'respect' from the management and nothing else. Just because a ballot has returned a yes vote (and to an impartial observer a 70% vote on a 30% return looks like a somewhat weak mandate) doesn't mean that a desirable outcome will result. It's just the first step in a long process.
