Johannesburg - The four unions representing coal workers in South Africa, the continent’s biggest producer of the fuel, rejected a pay offer by producers including Anglo American, Glencore and Exxaro Resources.
The companies proposed an increase of 4.6 percent, the Chamber of Mines, which represents them, said in an e-mail. The inflation rate was 4.6 percent in May.
The National Union of Mineworkers (NUM), Solidarity, the Association of Mineworkers and Construction Union and UASA labor groups rejected the offer, Franz Stehring, head of mining at UASA, said by phone Friday.
The NUM, the biggest labor group, wants a 15 percent raise for members, spokesman Livhuwani Mammburu said by phone.
The producers’ offer will “prolong the negotiations process,” Deon Reyneke, head of energy industry at Solidarity, said in an e-mailed statement.
