I think many BA staff recognise that times are changing, and that some of us will be changing work practices or be unemployed in the future.
Unfortunately, some other staff don't.
I think that they are in for an unpleasant surprise, despite being warned by the management and their colleagues.
I do wonder what these people do in their spare time if they don't read the papers or watch the news? It doesn't take a degree to see that future oil prices, the rise of the Arab carriers, Open Skies, open skies, increased aviation taxes and the toughest economic and demographic conditions for a couple of generations are all going against the airline industry and BA in particular.
Just saying "No" and stamping your feet isn't going to stop the changes.
