The Cuesta-Duarte Institute is a civil society association created in Uruguay in 1989 at the initiative of the central trade union, the Plenario Intersindical de Trabajadores – Convención Nacional de Trabajadores (PIT-CNT), with the overall objective of providing technical support to organised workers, seeking in this way to improve their performance in the representation of their peers within the framework of the class struggle and according to their political objectives.
