Oposición Sindical Obrera ("Working Class Union Opposition", abbreviatedOSO) was a clandestinetrade union movement inSpain. OSO was originally tied to theCommunist Party of Spain (PCE). Many of its members participated invertical union elections of 1963 in order to infiltrate theofficial regime union, includingMarcelino Camacho. OSO is considered the precedent for theWorkers' Commissions (CCOO). In the mid 60's thePCE abandoned the OSO in favour of the more successfulCCOO. When thePCE abandoned the organization thePCE (m-l), a 1964maoist split of thePCE took over the OSO and transformed it in its affiliated union. OSO disappeared in 1977 when it was transformed in theAsociación Obrera Asambleista (AOA).[1]
