International Workers' Day, also known as May Day, is celebrated on May 1st each year. It honors the contributions and achievements of workers around the world, advocating for labor rights and social justice. The day has its roots in the labor movement, particularly the Haymarket affair in Chicago in 1886, which highlighted the struggle for an eight-hour workday. Many countries observe International Workers' Day with parades, demonstrations, and various events that promote workers' rights. It serves as a reminder of the ongoing fight for fair wages, safe working conditions, and the importance of solidarity among workers globally.
