As Filipinos prepare to celebrate Labor Day on May 1st, the streets of Manila will once again fill with workers marching for better wages and working conditions. This tradition stretches back more than a century to 1903, when the Union Obrera Democratica Filipina organized the country’s first Labor Day rally. As we honor workers’ contributions to national development this May 1st, it’s worth revisiting the remarkable story of this pioneering organization that forever changed the landscape of Filipino labor relations.
The Union Obrera Democratica Filipina (UODF), established in 1902, stands as the Philippines’ first modern labor federation and the cornerstone of the country’s labor movement. Its emergence represented a decisive shift from older guild-based associations toward a politically conscious workers’ movement that reflected both the dreams and struggles of Filipino laborers at the dawn of American colonial rule.

Isabelo de los Reyes founded the UODF after returning from Spain, where his political education and exposure to European labor movements profoundly shaped his vision. De los Reyes gathered printers, lithographers, and representatives from various trades in Manila, creating a federation that quickly expanded to include unions from diverse industries like tobacco, carpentry, tailoring, and shoemaking. Though prominent industrialists initially held leadership positions, they soon withdrew, allowing workers themselves to assume key roles and cementing the organization’s grassroots character.
The UODF’s goals were both ambitious and comprehensive: improving working conditions through labor legislation, securing jobs for the unemployed, providing free education for workers’ children, and offering mutual aid to members in need. Drawing inspiration from socialist and anarchist thought, the union fought not just for economic improvements but for the broader liberation of the working class. Under de los Reyes and later Dr. Dominador Gomez, the UODF organized strikes and public demonstrations, culminating in the historic first Labor Day rally in 1903, which brought thousands of workers to Manila’s streets in a powerful display of solidarity.
Despite early victories, the UODF faced formidable challenges. American colonial authorities, fearing organized labor might fuel nationalist sentiment, responded with harsh repression. Leaders were arrested on charges ranging from sedition to embezzlement, while internal divisions and financial difficulties further weakened the organization. Though the union eventually collapsed, it succeeded in raising wages and establishing strikes as legitimate tools in labor relations. More importantly, it championed the principle of worker self-determination, laying the groundwork for future labor activism.
The UODF’s legacy remains remarkably relevant for today’s Filipino workers. Its pioneering efforts demonstrated the power of collective action and the importance of connecting labor rights to broader social and political goals. The union’s vision of worker empowerment—covering not just economic gains but also education, welfare, and dignity—continues to inspire as Philippine labor confronts contemporary issues like contractualization, wage stagnation, and the rights of marginalized sectors. The UODF’s experience underscores the need for strong, independent unions capable of advocating for workers amid evolving economic and political realities.
In the end, the Union Obrera Democratica Filipina represents the enduring struggle for workers’ rights in the Philippines. Its history offers both inspiration and caution, reminding today’s labor movement about the power of unity, the necessity of political engagement, and the ongoing fight for social justice—values that continue to resonate as workers across the Philippines prepare to march this Labor Day.
