I'm not arguing against unions. My comment was just that pay varies widely across the country, regardless of whether or not a union is in place, because of job markets and the cost of living. For the poster to scoff at $27/hr because she makes $40 is just kind of ignorant. That's all.
For the record, I'm part of a union in a CT hospital. The pay is good, no doubt, and better than non-union. However, I usually have 6-8 patients (in the ER), I RARELY get a meal break because there is never coverage, and the union is completely unresponsive when there is a problem. But I also realize that all unions, like people, are different.
