This is downvoted, I assume because people are maybe disagreeing with the principle rather than the validity of what you said.

A lot of large companies clearly do look at unions as something that forces them to pay more compensation for less work, which they'd have to justify to shareholders and the board. Even if the board would be cool with it, and they could make it fly with shareholders, leadership bonuses and stock grants are tied to performance. I really don't see where this is an incorrect statement to make.
