Workers from Freeport-McMoran Copper & Gold Inc’s Indonesian unit shout slogans during a strike in Kuala Kencana, Timika, in Indonesia’s Papua province July 5, 2011. About 8,000 workers at Freeport-McMoran Copper & Gold Inc’s Indonesian unit kicked off a seven-day strike on Monday, a union head said, in a move that could potentially disrupt operations. The workers have called for a re-negotiation of their working contract, demanding a wage rise from $1.5 to $3 per hour, since they said other Freeport workers around the world are paid at least $15-30 per hour, a union official said.
