Labor Day

Labor Day in the United States is a public holiday celebrated on the first Monday in September. It honors the American labor movement and the contributions that workers have made to the strength, prosperity, and well-being of their country.

Labor Day was promoted by the Central Labor Union and the Knights of Labor, who organized the first parade in New York City. After the Haymarket Massacre in Chicago on May 4, 1886, U.S. President Grover Cleveland feared that commemorating Labor Day on May 1 could become an opportunity to commemorate the affair. Therefore, in 1887, the United States holiday was established in September to support the Labor Day that the Knights favored.

History 

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 Laborin May 1882, after witnessing the annual labour festival held in Toronto, Canada. Oregon was the first state to make it a holiday on February 21, 1887. By the time it became a federal holiday in 1894, thirty states officially celebrated Labor Day.

Celebrations

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 often marks the end of the traditional summer season (although summer doesn't officially end until September 21), as students normally return to school the following week, although school year starting days now vary.

Retail Sale Day

To take advantage of large numbers of potential customers free to shop, Labor Day has become an important sale weekend for many retailers in the United States. Some buyers retailers claim it is one of the largest sale dates of the year, second only to the Christmas season's Black Friday.
