Power stems from the consent of the governed, whether the powers that be respect it or not. Employees don't vote for specific policies, but they vote for who they want to work for, and the candidate they pick always wins.
There are no governed here, especially in a right-to-work culture. Saying people vote for who they want to work for because they can vote with their feet is a bit like saying if you don't like your dictator, just move out of Venezuela. Reality is significantly more complicated than that.
