Not clear cut as we are in disagreement.
It does start off by saying if the majority do not support a strike then Ts and Cs would remain but if a strike goes ahead this cannot be guaranteed.
As BA can't pay some cc one rate and the strikers another I assume the majority vote will count.
If this is correct there will be a vote no campaign.
