Today is Labor Day, a day off from work, the last hurrah before the kids go back to school (or maybe you're saying hurrah because they ARE going back to school), and a time to fire up the grill for steaks or veggie burgers.  But you know that there is more to Labor Day than that. According to the US Department of Labor: 

Labor Day: What it Means

Labor Day, the first Monday in September, is a creation of the labor movement and is dedicated to the social and economic achievements of American workers. It constitutes a yearly national tribute to the contributions workers have made to the strength, prosperity, and well-being of our country.

Labor Day Legislation

Through the years the nation gave increasing emphasis to Labor Day. The first governmental recognition came through municipal ordinances passed during 1885 and 1886. From these, a movement developed to secure state legislation. The first state bill was introduced into the New York legislature, but the first to become law was passed by Oregon on February 21, 1887. During the year four more states — Colorado, Massachusetts, New Jersey, and New York — created the Labor Day holiday by legislative enactment. By the end of the decade Connecticut, Nebraska, and Pennsylvania had followed suit. By 1894, 23 other states had adopted the holiday in honor of workers, and on June 28 of that year, Congress passed an act making the first Monday in September of each year a legal holiday in the District of Columbia and the territories.
