An illegal strike that led to more than 600 employees being dismissed at the Mototolo mine run by Anglo American Platinum Ltd. has been resolved, and the workers will be reinstated, the company said May 30.

Under the agreement signed with the General Industrial Workers Union of South Africa, workers will be able to make up their lost income within the next four months by working additional shifts to make up for lost production, Amplats said

Union members downed tools May 12 following a dispute over changes the company made to the employees' medical program after buying the mine from Glencore PLC in 2018. The strike was in contravention of an interim South African court's interdict against strike action.

Amplats fired 643 underground workers after talks were unsuccessful.

The dismissed employees will report for duty May 31. The union also accepted that the proposed changes to their medical aid meet the requirement of the Labor Relations Act, the mining company said.

Amplats is majority owned by Anglo American PLC.
