I think part of the reason I don't really like unions is due to the fact that many of the things that they were originally founded to fight for have been achieved and legislated across the country.
i.e.
Safe work places (there are now federal and provincial laws that ensure/require this. If you don't think it's safe to work you don't have to, and believe me, the government agencies would love to nail your boss for making you do unsafe work.) No union needed for that.

Minimum wages (Minimum wage is still pretty crappy, but it's illegal for companies to undercut people by offering them less or to hire illegal immigrants and pay them less. You don't need a union to turn your boss in for that, and there are whistle blower laws in place to ensure you don't get screwed because of it)

Job security (Am I part of a union? No. Do I worry about job security? No. Why? Because I do a good job and am not afraid of being fired)

I can't really think of any other reasons unions should exist (I may be wrong, please give me some examples, I'm willing to hear them out, though I'm also likely to try to find flaws).

So seriously, pro union folks, give me other legitimate reasons why a union is necessary in this day and age. (I'm not being a dick, I'm serious)
