Labor Day--America's answer to International Workers Day (May 1).
In turn, International Workers Day commemorates the Haymarket Affair that took place in Chicago on May 4, 1886, a general strike for an eight hour work day, during which 4 were killed.
http://en.wikipedia.org/wiki/International_Workers%27_DayIronic, isn't it, that the world celebrates the day of a general strike in Chicago,Illinois, but the U.S does not recognize it?
Ironic, perhaps, but far from accidental.
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, which occurred in Chicago on May 4, 1886, US President Grover Cleveland feared that commemorating Labor Day on May 1 could become an opportunity to commemorate the affair. Thus, in 1887, it was established as an official holiday in September to support the Labor Day that the Knights favored.<1>
