COB
The Bolivian Workers’ Center (Spanish: Central Obrera Boliviana, COB) is the chief trade union federation in Bolivia. It was founded in 1952 following the national revolution that brought the Revolutionary Nationalist Movement to power. The most important affiliate of the COB was the Union Federation of Bolivian Mine Workers (FSTMB).
The COB represents about two million Bolivian workers, bringing together workers from various branches of industry and public services as well as consultation with many peasants’ and indigenous leaders.
