Does anyone know what is considered a ''majority Yes vote'' - if 51% of people vote yes will that be classed as majority enough for a strike to go ahead or do they need a vast majority ie. 80% etc?? If its the former then unfortunately there probably will be a strike (unless BA manage to stop it!) Does it also matter about a majority return ie. if only 30% of ballot papers are returned and there is a 90% Yes vote, will that mean that is not valid - as I don't really class that as a majority Yes vote?
