And just to be clear, is this someone refusing to take part in a strike that was called, either by their union, or by a union active in their section of the workforce? Cos that sounds very different to the situation being discussed in the SolFed statement, of sectional action being called by one union and other workers outside that section of the workforce crossing because they haven't been asked to go on strike that day.
The broader point of people who say they can't afford to strike, what unions can do to make sure they feel able to strike, and what the rest of the working class can do to ensure that their unions can keep paying and don't go bankrupt, is a big and important one, but maybe outside the scope of this thread? I can see it becoming pretty important if the current strike wave escalates any further.
