South Africa's National Union of Mine Workers will give notice of a strike at all mines represented by the NUM from Saturday in the event no agreement is reached in negotiations with the Chamber of Mines of South Africa by Wednesday, a source said Tuesday.
An offer was made by the Chamber after talks Monday, which the NUM will report to its members Tuesday before meeting with the Chamber on Wednesday, an NUM spokesman said.
The source said the offer was "very tempting" and several members represented by the NUM were willing to accept the deal, though any agreement must be accepted by all members as part of the centralized negotiations.
A 48-hour strike notice was originally going to be served last Thursday, before improved offers led to the postponement of the strike and the renewed negotiations Monday.
The NUM has been demanding a one-off Rand 1,100 ($78) payment for workers for 2017, an 8% pay rise for 2018 and 9% for 2019.
The Chamber represents Anglo American Coal, Delmas Coal, Exxaro Coal Mpumalanga, Glencore, Kangra Coal, Koornfontein Mines and Msobo Coal.
