Fifty-five years after the unanimous approval of copper nationalization on July 11, 1971, President Salvador Allende described it as 'the second national independence.' Today, the National Confederation of Copper Workers advocates for the renationalization of large-scale mining and the termination of subcontracting. Currently, approximately 80% of those employed by Codelco are contractors, and subcontracting accounts for roughly 75% of the workforce in the mining sector.
