I'll second everything you have said Gypsy. Many people who did not have the benefit of a union have no idea why they are needed. But I certainly know all of the horror stories of those who do not.
Employment laws in the United States protect workers now. Right to work should be law across the state as well as the whole nation. This is America... you shouldn't have to be forced to join a group just to work for someone.
The occasion hasn't arisen lately.
