Yep but that's again a dogmatic view as there is hints that anti-unionization measures are the kind of cost cutting that kills companies rather then the kind that makes them huge successes.
In companies with a healthy culture, maybe. But if staff unionizes, how's Amazon going to make them pee in a bottle to squeeze out a few more deliveries, without running into trouble with the union. I'm sure other companies have their own terrible anecdotes.
