USO - Unión Sindical Obrera

What USO - Unión Sindical Obrera does

USO (Unión Sindical Obrera) is an independent trade union confederation founded in 1961 and headquartered at Calle Príncipe de Vergara 13 in Madrid, Spain. It represents workers across multiple sectors — industry, services, citizenship attention, education, and private security — through a structure of territorial unions (Uniones Territoriales) operating nationwide and five sectoral federations: FI-uso (Industry), FS-uso (Services), FA-cuso (Citizenship Attention), FE-uso (Education), and FTSP-uso (Private Security). A dedicated pensioners' section (JUPEN-USO) and an international cooperation arm (SOTERMUN) extend the confederation's reach. USO is member-funded through dues and provides labor rights representation, collective bargaining support, legal advisory services (Asesoría Jurídica), training programs, union election campaign support, and a solidarity fund (Caja de Resistencia y Solidaridad) for members during labor conflicts.

The organization distributes services through territorial offices, a central Madrid headquarters, and a broad digital footprint including a dedicated mobile application, an extensive social media presence across eight platforms, and publications such as the USO Joven magazine. Recent product additions include the 2026 Calor Check heat-risk assessment tool. USO maintains international affiliations with the International Trade Union Confederation (CSI/ITUC), the European Trade Union Confederation (CES/ETUC), the Pan-European Regional Council (PERC) — which integrates 89 European trade unions — the Trade Union Advisory Committee to the OECD (TUAC), the Trade Union Confederation of the Americas (CSA), the European Trade Union Institute (ETUI), and the International Labour Organization (ILO). The organization is governed by a Secretary General (Joaquín Pérez, re-elected at the 2026 13th Confederal Congress), a Confederal Executive Commission, and a Federal Council, with a staff of approximately 125 professionals and member-elected delegates across Spain.
