Seriously? You just compared a union to the Tea Party? Unions are liberal organizations supported by the Democratic Party. The Tea Party is a Libertarian movement based upon individual freedoms. You may as well have compared Obama with Reagan and said their politics were the same.
This is a perfect example of how union supporters are uninformed. They blindly swallow every line the union feeds them. They do not take it upon themselves to be informed of BOTH the positive and negative consequences of being unionized.
Unions hinder free-market competition. The US economy is based on capitalism and competition. This is why unions continue to hurt the employees they represent, by trying to be socialist in a capitalist economy. In the end, it doesn't work, the numbers don't add up and the unions will fail, if not today then not far into the future.
You think this is a win? Far from it. A contract still needs to be negotiated. For those who don't know history, google UPS, teamsters, Philadelphia, 1967.
