WW could not of course have broken the strike had one not been called. So even if he had intended to break the Union, BASSA/UNITE gave him the ammunition to do just that. How would he have managed it otherwise?
I can understand your disappointment with your colleagues, but do you not feel that they are equally entitled to feel disappointment with BASSA/UNITE should they disagree with the aims of this strike? Further, surely you consider that while you are entitled to strike in an attempt to put pressure on a company, the company and its staff are also entitled to resist that pressure?
