Bloomberg reported that tomorrow, the National Union of Metalworkers of South Africa (NUMSA) plans to issue a notice for its members to halt their work at Anglo American Platinum Ltd.’s (OTCMKTS:AGPPY) refineries and smelters.

Members of the Association Mineworkers and Construction Union (AMCU) are already striking at the company’s operations.

As quoted in the market news:

The National Union of Metalworkers of South Africa will tomorrow issue a notice to down tools, Stephen Nhlapo, Numsa’s head of basic metals and energy, said today by phone. The union demands pay increases of as much as 10 percent and a 2,500-rand ($224) raise in the lowest-paid workers’ basic wage, he said.

‘We’re just looking at some legalities and adding the final touches’ to the notice, Nhlapo said.
