I agree on the first part. But "higher salaries, better work conditions, more benefits, and similar things" are usually part of left-wing political ideology too. So for me there is no surprises and nothing new in unions sharing/pushing "sociopolitical ideas currently in vogue in left-wing political circles".

If i understand correctly your point (and to paraphrase), unions are not setting the correct priorities between work condition and more general sociopolitical ideas. For me this is a good new : It mean works conditions are not that bad and that union want not just to take care of personal interest but of company interests as well. But this is a ideological stand point :)

And some may argue that's not the role of unions. But the role of union is to carry the worker voices. If this is the subjects workers want to talk about, i don't see any issue. If it's not, the union will just not meet enough workers to join them.
