Legally, Unite can wait until 14 March to call a strike, but I find it hard to believe that there will be such a delay.
My hunch is, as BASSA is on a sticky wicket regards the exact number that might
actually strike, they will play for time. Delay any strike announcement in the hope they can squeeze a face saving deal out of Willy.
My other hunch is that Willy will blink, and go for the compromise solution.
We shall see.
