While I agree that there are, in general, significant differences in positions on these things, this seems like a bad example to choose: after all, US rail workers went on strike over the safety, long hours, and being expected to work injured or sick, and President Biden signed off on laws making their strikes illegal.

Unfortunately, at least in the English-speaking world, many nominal workers' parties have largely bought into worker-hostile policies under Blair, Starmer, Clinton, Albanese, and so on.
