Modern labor struggle is social justice. Just see the most successful labor leader in recent years, Christian Smalls, see how he talks, and what he emphasizes. See also various union statements by Starbucks worker’s unions.
Climate change, gender equality, LGBTQ+ rights, BLM, #metoo, those are all integral to a modern union. And raising those among your labor concerns has proven to be effective in building up the solidarity required for meaningful action.
I guess whatever works, works - but I wonder how many union members actually support that and how many just go along because of the benefits and because there's no choice. I understand the original idea of unions, as means for improving worker's conditions, but this is not that. That's just generic leftist activism masquerading as worker's movement, and prioritizing things that have little to do with workers' benefit. Maybe that's why the unions are in decline now.

Maybe if they were more about the workers and less about the wokers, they had more willing members.
