See I sort of think historically, US unions were reactions to strongly abusive management at some point in company history. After they become entrenched, I agree that worker management relations can end up confrontational, and likely less efficient. But it's a two way relationship at the root there. But this isn't a forgone conclusion, for example worker relations seem to work fine in general in Germany which has actually institutionalized worker representation at a fairly high level in corporations.
