> Management wants to pay as little as possible for the most work and labor wants to get paid as much as possible for the least amount of work?

Well for example, at Netflix, management specifically paid extra for good labor and offered interesting problems, and in return we did extra work because we were motivated by the interesting problems and the great co-workers.

And at Google back in the day, they gave significantly more benefits than necessary to attract great talent.

So no, I'd say it's possible to create a non-adversarial workplace. The trick is keeping it that way as it grows, which is usually when unions come in.
