IWW and syndicalism

I’d be curious what the unions felt they weren’t getting. I’ve heard nothing but praises from the people I know who work for Costco. The prior ceo was big on employees even when people want him to pay less and lower benefits. He said no. I support the right of people to unionize but sometimes, you’ll end up with less. I do like their letter though. It’s a good letter and how you Should handle the situation.
