Yes they do, and they have wrecked many of the domestic auto companies! Why do you think Toyota, Honda, Daimler-Benz, BMW, Hyundai-Kia, and the likes built their plants in non-union, right to work states....hmmmm! Talk about outdated, arcane work rules and benefits agreements. Only through declaring bankruptcy are the domestic auto companies, and many municipalities, able to escape the overwhelming, unrealistic burden of certain union entities. I am NOT against Unions, just Union abuses and the corrupt politics of giving money to candidates, getting them elected, and then making agreements with those same people who are beholden to you (it works with both parties by the way and it is NOT the RIGHT way to represent your entire constituency!). I am for collective "bargaining" but not for "collective bludgeoning"! It was these issues, not the lack of producing the abject failure, "The VOLT", which caused the predicament of the domestic auto makers.
