On 29 September 2011 about 1,200 miners at Freeport’s Cerro Verde mining site began a 75-day strike. The participants were scheduled to walk off their jobs at 8:30 am Eastern Time. At midnight on the same day, 8,000 miners at Freeport’s Grasberg mine planned to begin a one month strike. The workers at both of these mines were part of the same miners union, all working towards the same goals.
The strikes began after wage talk attempts had failed. The union’s general secretary said, “Freeport’s offer was insufficient. There was no chance of reaching an agreement”.
