Ah, Labor Day, the most ironic of our national holidays. It's a day named for and intended to celebrate laborers and the Labor Force. Yet, the people least likely to have the day off are laborers. Management will get the day off, with pay even. Government workers will get the day off, paid, too. Most retail employees will either get today off with pay, or will have an extra day off at some point in the week. Some laborers and tradesmen will get the day off, but for most of them, it's a day without pay, so if they have the option, they'll go to work. Just. Like. Every. Monday. While everybody else "celebrates" Labor by not laboring and not giving a second thought to those who do.
"Labor", ironically, seems to have the least reason to celebrate Labor Day.
