It is worth noting that UNITE are the main contributor to the Labour party so with a general election likely to happen within 4 months or so; there is NO WAY they will want a public reation like the 12 day Xmas strike caused. They simply cannot risk the public turning their backs on what is already a wounded Labour party.
My own opinion is that this will be decided over and above BASSA's head and settled out of court at sometime before or during the imminent case.
