Taco Bell and AMC locations will be open, but the Post Office is taking the day off.

There’s a popular bumper sticker you might see around, especially if you live in a town with a strong attachment to manufacturing, that tends to go along the lines of “Do you love your weekend? Thank a union!”

Labor unions were once a widespread cultural force. The first Labor Day parade was held in 1887 in New York City, and that same year, Oregon made it a public holiday. By 1894, it became a federal holiday.

While labor activists and union leaders were among the earliest proponents of the holiday, it’s more generally aimed to honor all workers, and “the laboring classes,” according to the U.S. Department of Labor.

Labor Day Marks the Unofficial end of Summer

Labor Day has long served as the unofficial end of summer. In some areas of the country, school begins the week of Labor Day, though in many other places now, classes begin in August. 

While Labor Day is a salute to American workers, not everyone gets the day off. 

Many businesses are open on the holiday, and Labor Day sales are a long-standing American tradition.

Labor Day sales exist to attract the attention of people who might take the day off to finally buy that new TV, or to attract parents who need to pick up something for their school-age children. Along with Black Friday and Memorial Day, it’s one of the biggest shopping days of the year.
