> I'd much rather see greater employee ownership in companies though rather than unions. Union and management negotiations are often a zero sum game. A win for one side is a loss for the other. And in between you can have damaging strikes or a breakdown in relationships. It's an us vs. them mentality, which isn't great for teamwork.

While this is generally true in the US system, it's not inherently true. It's like any other relationship - if there is trust and mutual understanding, then a good union can make a company better than it would have otherwise been. If the union exists as a response to abusive ownership, then it should hardly be surprising that the parties go to war, but it's ownership that drives that divide.
