Labor Day versus May Day
The date of May 1 (an ancient European folk holiday known as May Day) emerged in 1886 as an alternative holiday for the celebration of labor, later becoming known as International Workers' Day. The date had its origins at the 1885 convention of the American Federation of Labor, which passed a resolution calling for adoption of the eight-hour day effective May 1, 1886.[17] While negotiation was envisioned for achievement of the shortened work day, use of the strike to enforce this demand was recognized, with May 1 advocated as a date for coordinated strike action.[17] The proximity of the date to the bloody Haymarket affair of May 4, 1886, further accentuated May First's radical reputation.[13]
