10,000 miners walked out from the Grasberg gold mine (pictured) in Papua, owned at 90% by Freeport-McMoRan Copper & Gold, with central see in Phoenix (Arizona, USA).
The central reason for this strike is that the company refused to raise salaries to $3 per hour (now it is $1.5) as well as to improve working conditions. Allegedly the company has even shot against union leaders.
Grasberg is the World's most profitable gold mine but is also damaging the local environment and workers consider legitimately that they deserve at least a greater share of the cake.
