Fearing further conflict, legislation making Labor Day a national holiday was rushed through Congress unanimously and signed 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 stir up negative emotions linked to the Haymarket Affair, which it had been observed to commemorate. All U.S. states, the District of Columbia, and the territories have made it a statutory holiday.
