7 December, 2010

By a vote of 521 to 398 on 6 December, members of Sindicato de los Trabajadores de Collahuasi voted to end a 32-day strike against the world’s third largest copper miner, located in Chile. The Union of Workers of the Collahuasi Copper Mine and Doña Ines de Collahuasi, owned jointly through 44% stakes each by AngloAmerican and Xstrata, resumed talks early last week with help from Roman Catholic Prelate Marco Antonio Órdenes, Bishop of Iquique.

The union's Second Director, Carlos Daniel Rojas, told the ICEM early today that Bishop Órdenes succeeded "in opening the door" with the company when there appeared little hope that talks would resume, and the union took it from there to work out a settlement.

The final resolve came in negotiations over the weekend and early Monday, 6 December, with an acceptable compromise.

The vote Monday night ends the longest private-sector Chilean copper strike, surpassing one of 26 days in 2006 at the Escondida mine, owned 57.5% by BHP Billiton and 30% by Rio Tinto.

 Collahuasi Miners Vote on the Evening of 6 December

Terms of the settlement will give the 1,551 miners of Collahuasi a wage increase of 16.3% over a 42-month period, and a bonus payment of 14 million pesos (US$28,733). Other key issues in the strike, which began on 5 November, were company-paid health care and education costs for miners’ children. The union did make advances in both these areas from prior levels paid by the company. 

The strike was marked by a united workforce led by President Manuel Muñoz and Second Director Rojas. The miners of Collahuasi took up residency in the Santa María School in Iquique, and staged peaceful and near-daily manifestations in that city. Those demonstrations were strategic in order to draw attention to their cause of gaining adequate health coverage and educational stipends from an employer that posted net profits in 2009 of US$1.56 billion due to high copper pricing.

Last night’s vote took place inside the Santa María School. Collahuasi miners were scheduled to return to work high in the Atacama desert of Chile’s northern Region I, some 285 kilometres from the port city of Iquique, today, 7 December.

"The Collahuasi miners and their families showed strength and fortitude in a dignified and peaceful way against an enterprise intent on maintaining production and turning profits," said ICEM General Secretary Manfred Warda. "For that, they have earned the pride and admiration of the world's mining unions."
