Samuel Gompers, founder of the American Federation of Labor, described Labor Day in this fashion, "Labor Day differs in every essential way from the other holidays of the year in any country, All other holidays are in a more or less degree connected with conflicts and battles of man's prowess over man, of strife and discord for greed and power, of glories achieved by one nation over another. Labor Day...is devoted to no man, living or dead, to no sect, race, or nation."
In 1898, Samuel Gompers called it "the day for which the toilers in past centuries looked forward, when their rights and their wrongs would be discussed...that the workers of our day may not only lay down their tools of labor for a holiday, but upon which they may touch shoulders in marching phalanx and feel the stronger for it."
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.
