I am not sure BA will ever say that if you go on strike, you will be dismissed, unless a court rules that the proposed action if voted for, is unprotected. If the courts do, then it would be a brave soul to carry on regardless.
Now, I have no idea, but if the ballot delivers a yes and BA take the matter to court and win, does that mean that all items listed on the current ballot paper will be seen as a continuation of the existing dispute? If so, then that is it as far as industrial action goes.
