Because the third 'corrupt thing' operates in favor of the employee.

Instead of the corrupt company doing everything it can to exploit employee labor, it has to fight the corrupt union doing everything it can to exploit the corporation. Otherwise if you want to argue that we should remove all corporations like we do unions because of their corruption, then I'd be all for that.

Are you asking for the purpose of a labor union and insinuating that all labor unions are corrupt?

I lived in the Michigan for a couple of decades and observed the behavior of the Teamsters and UAW firsthand so insinuation is not even necessary.

The Teamesters and UAW [1] are not all unions. It's a big world out there, so don't insinuate things about unions that you don't even know exist.

Nor should you pretend you know whether a future union at HCL is going to be one of the good ones or one of the corrupt ones.

If you pay closer attention, you'll notice that I made no such claim.

If you're an auto worker, how easy is it to get completely get away from UAW?
