The National Union of Mineworkers (NUM) has called for a strike in the coal sector after negotiations between the union and the Chamber of Mines collapsed.
The union accused the Chamber of Mines of being arrogant and negotiating in bad faith.
NUM confirmed on Wednesday afternoon that it had received a certificate of non-resolution to the dispute from the Commission for Conciliation, Mediation and Arbitration (CCMA).
The union is demanding a once-off payment of R1 100 for 2017, an eight percent wage increase for 2018 and a nine percent increase for the third year.
The union further said that it would only sign a three-year agreement on condition that the Chamber of Mines resolves to remain a part of the Collective Bargaining Forum.
NUM said that it was “determined to force the companies to lend an ear to its wage demands”.
A date for the strike will be issued in due course.
