Well HF in 2007 more than 96% of the 8,462 staff who took part in a postal ballot voted in favour of action, with just 330 voting against. The turnout was 80%.
As far as the numbers of those actually walking out, well, I have been in BA for over 37 years and have experienced a few disputes before, so I know what to expect. All I can say is that I have never seen the cabin crew more resolute and focussed as they are now. There is a tremendous feeling of camaraderie and unity.
BA are making a huge mistake if they doubt the resolve of their employees to support their union and each other. When this is all over, Walsh will try and dodge the bullet again as he did over T5. Just watch him wiggle out of this one! It will be toe curling to watch. Deja vu all over again.
