SANTIAGO, Oct 8 (Reuters) - Chilean state-owned copper miner Codelco said on Thursday that unionized supervisors at its Radomiro Tomic mine have gone on strike after rejecting a labor deal, adding that operations have not been affected.
"With the start of the strike the company activated a contingency plan, which has as its main objective to protect the safety of those that are still working and to assure operational continuity, which has thus far been unaffected," said Codelco.
The striking union at Radomiro Tomic consists of 183 professionals and supervisors.
Radomiro Tomic produced 327,300 tonnes of copper last year, almost 20 percent of Codelco's total output.
The strike is another headache for Codelco, the world's largest copper producer, which has struggled this year with labor disputes, engineering issues and bad weather on top of six-year lows in the copper price.
