The 2026 official global theme, set by the International Labour Organization (ILO), is "Decent Work for All in the Digital Era", with specific focus on closing the gender pay gap, expanding social protections for gig and informal sector workers, and mitigating job displacement risks linked to rapid artificial intelligence adoption. The choice of May 1 as the official date for International Workers' Day traces directly to the 1886 Haymarket Riot in Chicago, United States. At the time, most industrial workers were forced to work 10 to 16 hour shifts six days a week, with no overtime pay, safety regulations, or job security. Labor unions across the US organized a nationwide general strike starting on May 1 of that year, demanding a standardized eight-hour workday. On May 4, a peaceful protest in Chicago's Haymarket Square turned violent when an unidentified attacker threw a dynamite bomb at police officers, leading to multiple deaths on both sides. Eight radical labor activists were later convicted in a widely criticized biased trial, with four executed by hanging despite a lack of concrete evidence linking them to the attack. In 1889, the Second International, a global federation of socialist and labor parties, held its founding congress in Paris, and voted to designate May 1 as an annual day of international labor solidarity to honor the Haymarket martyrs and continue the global push for the eight-hour workday. The decision turned the date into a global focal point for labor advocacy, with countries across Europe, Latin America, Africa, and Asia adopting the date as an official public holiday to recognize workers' contributions. For 2026, planned events across the world include mass marches organized by trade unions, policy forums to discuss updated labor regulations for remote and platform workers, community fairs offering free legal advice to low-wage workers, and educational events to teach young people about the history of the labor rights movement. Unlike the US and Canada, which mark Labor Day on the first Monday of September to distance the holiday from its radical labor roots, more than 160 countries worldwide recognize May 1 as the official International Workers' Day, with most granting workers a paid public holiday for the occasion.
