I have a non-union job and my employer treats me quite well. I work and I get paid for that work. I have benefits too. Guess what, I didn't need a union.
My employer pays me a salary with which I purchase insurance, fund my retirement and pay taxes. I don't pay union dues.
If I was in a union and paid dues, would those dollars buy insurance, fund a 401k or pay the taxman? Would they pay my expenses when the union drives the company into bankruptcy?
