An alternative thesis maintains that the idea of Labor Day was the brainchild of Peter J. McGuire, a vice president of the American Federation of Labor, who put forward the initial proposal in the spring of 1882.[2] According to McGuire, on May 8, 1882, he made a proposition to the fledgling Central Labor Union in New York City that a day be set aside for a "general holiday for the laboring classes".[7] According to McGuire he further recommended that the event should begin with a street parade as a public demonstration of organized labor's solidarity and strength, with the march followed by a picnic, to which participating local unions could sell tickets as a fundraiser.[7] According to McGuire he suggested the first Monday in September as an ideal date for such a public celebration, owing to optimum weather and the date's place on the calendar, sitting midway between the Fourth of July and Thanksgiving public holidays.[7]
