This seems like the obvious choice for me on this one. It’s rather a US-centric topic though in a sense, if you don’t mind my saying. We don’t have a labor day over here, nor do we know what one is (or even a labour day, for that matter).
Nevertheless, we do have to work for a living, which I have to admit is rather a pain, although not as much pain as my missus went through when she was in labo(u)r. And so we go full circle.
Enjoy the tuneage.
