Workers' Socialist Movement (Puerto Rico)

The Workers' Socialist Movement (Spanish: Movimiento Socialista de los Trabajadores, MST) is a Puerto Rican democratic socialist revolutionary organization, formed in 1982 and dedicated to the self-organization and self-emancipation of the working-class in Puerto Rico, as well as international solidarity with the workers struggles worldwide. It is usually known as the "MST", and its youth section is the Unión de Juventudes Socialistas (Union of Socialist Youth), also known as the "UJS-MST" or simply "UJS". The MST supports a socialist and independent Puerto Rico.
