Labor Day is an American federal holiday observed on the first Monday in September (September 3 in 2012) that celebrates the economic and social contributions of workers. In 1882, Matthew Maguire, a machinist, first proposed the holiday while serving as secretary of the CLU (Central Labor Union) of New York. Others argue that it was first proposed by Peter J. McGuire of the American Federation of Labor in May 1882, after witnessing the annual labor festival held in Toronto, Canada.
Oregon was the first state to make it a holiday in 1887. By the time it became a federal holiday in 1894, thirty states officially celebrated Labor Day. Following the deaths of a number of workers at the hands of the U.S. military and U.S. Marshals during the Pullman Strike, the United States Congress unanimously voted to approve rush legislation that made Labor Day a national holiday; President Grover Cleveland signed it into law a mere six days after the end of the strike. The September date originally chosen by the CLU of New York and observed by many of the nation's trade unions for the past several years was selected rather than the more widespread International Workers' Day because Cleveland was concerned that observance of the latter would be associated with the nascent Communist, Syndicalist and Anarchist movements that, though distinct from one another, had rallied to commemorate the Haymarket Affair in International Workers' Day. All U.S. states, the District of Columbia, and the territories have made it a statutory holiday.
The form for the celebration of Labor Day was outlined in the first proposal of the holiday: A street parade to exhibit to the public "the strength and esprit de corps of the trade and labor organizations",followed by a festival for the workers and their families. This became the pattern for Labor Day celebrations. Speeches by prominent men and women were introduced later, as more emphasis was placed upon the civil significance of the holiday. Still later, by a resolution of the American Federation of Labor convention of 1909, the Sunday preceding Labor Day was adopted as Labor Sunday and dedicated to the spiritual and educational aspects of the labor movement.
The holiday is often regarded as a day of rest and parties. Speeches or political demonstrations are more low-key than May 1 Labor Day celebrations in most countries, although events held by labor organizations often feature political themes and appearances by candidates for office, especially in election years.Forms of celebration include picnics, barbecues, fireworks displays, water sports, and public art events. Families with school-age children take it as the last chance to travel before the end of summer recess. Similarly, some teenagers and young adults view it as the last weekend for parties before returning to school, although school starting times now vary.
