Coal miners embark on strike
South African coal miners began a strike on Sunday after wage talks collapsed last week, disrupting the sector that produces the country's electricity and exports coal to Europe and Asia.
"The strike has just started. As expected our workers have downed tools," NUM spokesman Livhuwani Mammburu told Reuters.
Two smaller unions which mostly represent skilled workers and supervisors accepted the coal companies' offers last week.NUM's arch rival, the Association of Mineworkers and Construction Union (AMCU), has not accepted the offer but its membership levels are small.
The Chamber of Mines, which represents Glencore, Anglo American Coal and Exxaro, said last week that the coal producers had raised their offer to increase wages by up to 8.5 percent for the lowest-paid workers, from 8 percent previously.
South Africa's inflation rate is 4.6 percent.
