The cordones were established by the independent activity of working class people and were initially established to pressure the government to socialize a number of companies that refused to accept workers rights. Their formation were extended and their creation-pace accelerated in response to sabotage and strikes organized by employers' organizations and the Bourgeoisie that aimed to destabilize the Salvador Allende democratically elected socialist government and derail the implementation of a socialist programme. Initially created as organs to exert social pressure on the ruling government, they ultimately became a base for working-class political power itself. The first cordón was established on June 19, 1972, when workers from 30 different factories join to formulate the Cordon Cerrillos.
Structure
Each Cordón was a group of factories and companies, which coordinated the tasks of workers in the same zone. By the time the Salvador Allende government was overthrown on 1973 [Chilean coup d'état|September 11, 1973 military coup] 31 cordones had been established and were operational. Of the 31 cordones 8 of them were within the Chilean capital of Santiago.
