Members of the National Union of Metalworkers (Numsa) will march through Johannesburg's city centre on Saturday in a show of solidarity with other unions.
National spokesman Castro Ngobese, said the Congress of South African Trade Unions (Cosatu) had taken a decisive resolution for all affiliates to give their political and mass support to mineworkers in their struggle for a living wage.
The protesters would converge at the Library Gardens at 10:00 and make their way to the labour department in Braamfontein to hand over a list of demands. These included scrapping labour brokers.
Marchers would then proceed to the Chamber of Mines to submit a demand for a "living wage" for mineworkers.
Their last port of call would be the offices of the Gauteng premier.
"We will hand over a memorandum of demands to the government to scrap the commodification (sic) of Gauteng highways through e-tolls," Ngobese said.
"We will also ask them to stop the mooted implementation of the youth wage subsidy as proposed by the National Treasury in cahoots with apartheid apologists, the Democratic Alliance."
