National Union of Mineworkers South Africa (Numsa) has called on its members to take part in the strike organised by the South African Federation of Trade Unions (Saftu) on Wednesday.

Addressing members of the media on Tuesday, Numsa's general secretary Irvin Jim said the suggested minimum wage is a continuation of racism and should be scrapped is it exploits black workers.

"Through the labour bills, they use their proximity to power to extend, to defend and to maintain the continuation of the racist accumulation path of white monopoly capital through the super exploitation of black and African labour," Jim said.

He added that the union has received a few threats to not partake in the strike but they are not deterred.

"We have received reports of employers deliberately misleading by claiming that Numsa members may not participate in the strike because it is not specifically named in the Section 77 certificate granted by Nedlac.

"The strike tomorrow is to demand this real living wage in the form of the national minimum wage and to reject the insult of R20 per hour imposed in the labour market by the ANC government, which takes the black  and African working class back to the racist apartheid fault lines," said Jim.

Numsa, which has over 30 000 members, said those against the strike must remember that workers have a constitutional right to take part.

Unions are embarking on a national strike on Wednesday demanding that the national minimum wage not be implemented.
