National AFL-CIO Day

National AFL-CIO Day, observed on December 5, recognizes the formation and enduring work of the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO). Created in 1955 through the merger of two major labor organizations, the AFL-CIO brought workers together around shared goals such as fair wages, safe workplaces, reasonable hours, and a stronger voice on the job.

The observance is an opportunity to reflect on the contributions of organized labor and the role unions have played in improving working conditions and supporting working families. On December 5, people can learn more about labor history, recognize the dedication of union members, and consider how cooperation and collective action continue to shape workplaces and communities.

National AFL-CIO Day is observed on **December 5** in recognition of the creation of the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO). On December 5, 1955, the American Federation of Labor and the Congress of Industrial Organizations formally merged in New York City, creating the largest federation of labor unions in the United States. The merger brought together organizations that had developed separately and, at times, competed with one another over union membership, industrial strategy, and political priorities.

The AFL had been founded in 1886 as a federation primarily representing skilled craft unions, while the CIO emerged during the 1930s to organize workers across entire industries, including steel, automobile manufacturing, and electrical production. Their differences reflected major debates within the American labor movement about how unions should be structured and whom they should represent. By the early 1950s, however, cooperation became increasingly important, particularly in response to employer opposition, legislative restrictions on unions, and the need for greater national coordination. The merger was led by AFL president George Meany and CIO president Walter Reuther.

Over time, December 5 has served as an occasion to reflect on the AFL-CIO’s role in the history of organized labor. The federation has advocated for collective bargaining, workplace safety, higher wages, limits on working hours, civil rights, retirement security, and stronger protections for working people. Its affiliated unions have also participated in political campaigns, community organizing, international labor initiatives, and efforts to preserve the rights won through earlier labor struggles.

The cultural significance of National AFL-CIO Day lies in its emphasis on solidarity among workers and unions with different histories and occupations. It commemorates not only the 1955 merger but also the continuing influence of organized labor on American social and economic life. On December 5, labor organizations and supporters may use the observance to highlight the contributions of union members, educate the public about labor history, and consider the continuing challenges facing workers.
