On the other hand, I have never been in one, and I can see how they could be useful in cases of a business that takes advantage of its employees. What I don't get is why people would form/join a union rather than finding a different way to make money if they are being abused.
My distaste for unions isn't based upon insider knowledge like it is in cases of things I have seen and been a part of from all angles- inside and out. I am looking at unions strictly from the perspective of an outsider looking in. I have never even been around anyone who was in a union, as far as I know.
I have read all the justifications for labor unions, and how the benefits they extracted from employers now grace us all, union or not. But would none of those things have come about anyway, given time and innovation? And what good things will never come about (and never be missed) due to the actions of labor unions? It's like those who claim that since "the government invented the internet" (no, it didn't, but that's another issue), anyone who uses the internet to criticize government is a hypocrite. Diseases can have beneficial side-effects, that doesn't mean you try to get infected.
So, I guess my feelings on Labor Day are pretty typical. Relax and ignore the original excuse to close some government offices.
