Background

On 29 September 2011, about 1,200 miners at Freeport’s Cerro Verde mine began a 75-day strike, with 8,000 miners at Freeport’s Grasberg mine also planning a one-month strike. [source: nv-database] The Peruvian government’s Labor Ministry ruled the strike legal, barring Freeport from hiring outside contractors, but the company allegedly hired contractors anyway. [source: nv-database] On 10 October, para-military police opened fire on protesters in Timika, killing one and wounding several. [source: nv-database] On 17 October, fifteen Cerro Verde miners started a hunger strike in response to the violence, and hundreds blockaded the mine. [source: nv-database] The 110km pipeline was cut in several places, and three contractors were killed in an ambush. [source: nv-database] On 19 October, Freeport suspended all operations. [source: nv-database] The government urged resolution through the Industrial Court, and the union reduced its demand to $7.80 per hour. [source: nv-database] After nearly two more months, Freeport agreed to a 37% wage increase, improved housing allowances, educational assistance, and a retirement savings plan, and all workers were allowed back to their positions [source: nv-database].
