Developments: 2. The Spanish trade union Unión Sindical Obrero (USO) has initiated efforts to expand its influence and defend worker rights through both organizational campaigns and legal action. In early September, the union launched the “Sé el cambio, tú decides” (Be the change, you decide) campaign, aiming to increase its number of union representatives to 15,000 by the end of 2028. The initiative encourages workers to run as candidates in upcoming union elections to strengthen representation across various sectors and administrations. By late September, the union engaged in legal disputes in Cuenca. USO filed two lawsuits against the Diputación Provincial de Cuenca regarding modifications to the Job Position Relationship (RPT). One lawsuit was filed by a staff delegate and president of the personnel board concerning changes to their specific assignment and functions, while a second lawsuit was filed by the union to defend collective bargaining and the public employees affected by the redistribution of positions. ## Timeline ### 2026-09-23: Unión Sindical Obrero files lawsuits against Cuenca Provincial Council The USO union has filed two lawsuits against the Diputación Provincial de Cuenca challenging job position modifications and changes to staff assignments. 2 sources. https://clstr.news/cluster/unin-sindical-obrero-files-lawsuits-against-cuenca-provincial-council ### 2026-09-09: USO launches campaign for Spanish union elections The Spanish union USO has launched a campaign to recruit candidates for upcoming union elections, aiming to increase its number of representatives to 15,000 by 2028. 4 sources. https://clstr.news/cluster/uso-launches-campaign-for-spanish-union-elections --- Cite as: Unión Sindical Obrero activities in Spain.
