The term make it sounds like a good thing, however I do not know if this was really a net positive. It might have helped the companies but isn't this anti-competitive at the employee level?
I might be wrong but that's the impression I get when talking with US people about unions and workers rights.
Think of it like a football club holding a vote to flatten player pay. The benchwarmers will be falling over themselves to unionize, and the top players will be looking where to move too.
This is why union efforts fail, which many find perplexing. The most valuable players get better deals negotiating without a union.

Aren't all of these industries where the top workers get fat plates and others are pushing hard to get there?
Generally when workplaces unionize, jobs are clearly delineated, and everyone in that role has a defined pay.
