Peruvian Cerro Verde Miners Launch Legal Indefinite Strike

10 October, 2011

A branch union of the ICEM-affiliated National Miners’ and Metalworkers’ Union (FNTMMSP) of Peru is continuing its struggle for a decent new collective agreement at the Sociedad Minera Cerro Verde copper and molybdenum mine in southern Arequipa region. For the first time in the 40 year history of the mine, national government declared industrial action to be legal, as all 1,220 FNTMMSP members downed tools on 29 September for indefinite strike action.

The legal status for the strike means the ministry of labour will arbitrate negotiations, with both sides meeting this afternoon, Monday, for talks. Striking miners are being replaced with 600 scabs and management staff in company efforts to continue production, breaching Peruvian labour law. If company negotiators continue to push regressive proposals, the union will demand the government and Congress send labour inspectors to determine operations are in line with regulations. This would paralyse all production. The branch union general secretary Leoncio Amudio Peña alerted labour authorities to the pending request for inspections on 8 October.

Cerro Verde is offering workers a rise of less than US$1 per day, whereas the union seeks US$3. Local management also wants to replace future salary increases with a production bonus. As well as improved wages, strikers are demanding improved working conditions and better health and safety conditions. Branch general secretary Peña reports that the company only offers solutions to 4 out of 40 union demands. Union and management positions are also far apart on the length of the agreement, with the union wanting a one-year duration and the company originally seeking 5 years, now 3. The previous agreement which expired 31 August was 3-year, but that was extended as a one off in exchange for company concessions.

The strike was preceded by a 48-hour work stoppage in early September and an indefinite strike mid-September that was suspended due to a technicality making it illegal.

Cerro Verde produced 312,336 tonnes of copper in 2010, 2% of the world’s copper creating a net profit of US$1.05 billion. The open-pit mine is owned by US-based Freeport-McMoRan (53.7%), SMM Cerro Verde Nederlands (21%), a unit of the Japanese Sumitomo Corp., and Peru-based Compania de Minas Buenaventura (19.3%). Mining profits are soaring on global markets due to increased metals prices, with massively increased profit margins not shared with workers.
