NUM said on Monday that it will serve a 48-hour notice to go on strike in the coal sector on Thursday, with the strike scheduled to officially commence on Sunday 19 November 2017.
NUM members represent about 70% of employees in the coal mining sector.
On Wednesday 8 November, the NUM workers were awarded a certificate of non-resolution to the dispute by the Commission for Conciliation, Mediation and Arbitration (CCMA) after the Chamber of Mines failed to accede to their demands.
The NUM still demands R1 100 once off for the year 2017 and 8% for 2018. The NUM will only sign a 3 year agreement provided the Chamber of Mines accepts to remain in the Collective Bargaining Forum. The NUM will demand 9.5% for the 3rd year.
"The Chamber of Mines continues to be arrogant and negotiating in bad faith," the union says, adding that it is determined to force the companies to lend an ear to its wage demands.
