JOHANNESBURG, Sept 9 (Reuters) - South African coal producers have raised their wage offer to unions, a spokeswoman for the chamber of mines, which negotiates on behalf of the industry, said on Wednesday.
The spokeswoman could not provide any further details but a union source said the offer had been raised to a range of between 6 to 7 percent, depending on the mine and category of worker, from a previous offer of 5.5 to 6.5 percent.
