Stuff like “Unions aren’t guaranteed to give you a raise, or any other benefits,” “Unions just want you to join so you can pay dues to them (think about all the things you can buy with 1% of your income!),” “Unions get in the way of workers having a healthy relationship with management,” “Unions make things less efficient, so we may dip into unprofitability and have to close down the factory…” Employers also often hire “neutral third parties” to tell employees that unions can be good, or used to be good, but aren’t at [employer].

Joining a union is the sensible thing to do, but employers fighting tooth and nail and breaking every slap-on-the-wrist law on the books is also the sensible thing for them to do, so they do everything from anti-union pamphlets to one-on-one intimidation meetings to calling ICE on their pro-union immigrant workers
