As I've said before when we're all enjoying Labor Day here in America, don't forget who to thank. Namely, unions. As, "CBS Sunday Morning," discussed in a recent segment, unions are on the rise again in America as workers are seeing how important they still are--especially with the rise of the latest mega-corporations. Unions are why you even have a weekend, let alone an extended weekend. Enjoy Labor Day if you're here in the United States this weekend, and make sure you thank unions.
