Union pressure is fine.
However, remember that employees have the power to unionize because the law prohibits employers from preventing it. Before that law, the practice of employers was to fire all union organizers.
Was that abusive, firing someone for being involved in union organizing?
Seems to me that it make perfect sense. Talk about something that really affects business pretty profoundly! There's nothing like a union to gum up the works.
But that may be the answer in Michigan.
If employers won't be reasonable and not abuse their authority like this guy.
And if folks are so skittish about the law that neither legislation nor any sort of judicial settlement is acceptable,
then maybe what needs to happen is one of the big powerful local unions needs to intervene and offer to set up a chapter in this guy's company.
He can't stop that, or fire the organizers.
And then he'll have a whole lot more supervision of every single act he takes than any of the other proffered solutions.
Much better than having judges expand the common law to include their own personal sense of what the law should and should not be.
