I can assure you that in Michigan unionism is indeed forced.
Here's the way I see it. If a group of business owners got together and decided what prices they were going to charge for their services, the government would scream collusion. But when a group of workers get together and decide what prices they're going to charge for their services, the government forbids them from seeking other suppliers.
If unionism is truly forced in Michigan, in a criminal mafia sense, then that is something that needs to be dealt with using criminal extortion, RICO laws, etc.
Companies also have a right to get together and decide what they want their prices to be, and that is why antitrust collusion laws are nonsense.
When a group of workers gets together and decides what they want their prices to be, then of course companies have the right to seek other workers, and laws which prohibit that are nonsense as well.
But by the same token, companies also have the right to agree to terms such as wages, or even union membership, and that is why RTF is also another piece of nonsense legislation.
You asked about Bully.... I worked summers at a Union paper mill for 2 weeks (college summer job). I went to the non-union competitor in town for safer working conditions because you are threatened to join or get your head beat.
That's really shitty, but there are already laws against physically threatening someone.
RTA is not a law against physically threatening someone, it is a law that interferes with private contracts.
