So. I and my employees would give them free reign to dictate to us how the shop should be run and how I should base my pay scale? Shouldn't all that be left to the business owner and not an outside party? Under a union plan, which basically is not looking out for me, would more than likely handcuff me to make dire choices!

Stand up for what is right, even if you have to stand alone.
