Labor Day initial proposal in the spring of 1882. 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". 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. According to McGuire he suggested the first Monday in September as an ideal date for
Labor Day 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. Labor Day picnics and other public gatherings frequently featured speeches by prominent labor leaders. In 1909 the American Federation of Labor convention designated the Sunday preceding Labor Day as "Labor Sunday", to be dedicated to the spiritual and educational aspects of the labor movement. This secondary date failed to gain significant traction in popular culture. In 1887 Oregon became the first state of the United States to make Labor Day an official public holiday.
