International Workers' Day

Uruguay · Date: Friday, May 1, 2026

International Workers' Day, also known as May Day, is a public holiday in Uruguay celebrating labor rights and the labor movement. It is marked by marches, speeches, and gatherings organized by trade unions across the country.

Origin & history

International Workers' Day commemorates the Haymarket affair in Chicago in 1886, a pivotal event in the struggle for an eight-hour workday. In Uruguay, the holiday has deep roots in the early 20th-century labor movement, which gained strength with the influx of European immigrants and socialist ideas. The first May Day celebrations in Uruguay occurred in the late 1880s and early 1890s, organized by anarchist and socialist groups. The holiday was officially recognized as a public holiday in Uruguay in 1905 under President José Batlle y Ordóñez, a progressive leader who championed labor rights. Batlle's government introduced many social reforms, including the eight-hour workday and women's suffrage, making Uruguay one of the first countries in the Americas to adopt such measures. The establishment of May Day as a holiday was part of this broader effort to improve workers' conditions and integrate the labor movement into the political mainstream.

Customs & traditions

On International Workers' Day in Uruguay, the main tradition is a large, peaceful march organized by the PIT-CNT (Plenario Intersindical de Trabajadores – Convención Nacional de Trabajadores), the country's central labor union. The march typically starts in the morning and proceeds from the Obelisco to the Plaza de la Independencia or the Palacio Legislativo in Montevideo. Participants carry banners and flags representing various unions and political groups, and union leaders deliver speeches emphasizing workers' rights, social justice, and current labor issues. Many Uruguayans also attend cultural events, concerts, and gatherings with family and friends. While there are no specific foods exclusively associated with the holiday, traditional Uruguayan asado (barbecue) is common at social gatherings. In addition, the day often involves public displays of solidarity with international workers' movements.
