the latter isn't necessarily bad for the worker, e.g. if a tech union tries to force divestment from Israel
if more money for workers is involved, sure, I'm with you. but I kind of doubt it. If the (tech) union spends more effort pushing political things unrelated to money, best of luck to them. for unions outside of tech, this seems like less of an issue
In America, it is illegal for a union to bargain for things like not doing business with Israel. The union can put out statements about how they don't support trade with Israel, etc. and hope that management takes the feelings of its employee union seriously, but how often do you think that happens?
The law prevent businesses from boycotting Israel, they don't say anything about divestment.
