Johannesburg The Association of Mineworkers and Construction Union (Amcu) wants to expand the platinum sector strike.
"We have filed an application with Nedlac [National Economic Development and Labour Council] in Rosebank," Amcu president Joseph Mathunjwa said on Thursday.
"We want our workers in the gold and coal sectors to join us," he told hundreds of Amcu members gathered outside Impala Platinum's head office in Johannesburg.
The workers had marched from a park in Dunkeld West to deliver a memorandum to Implats.
Amcu-affiliated mineworkers in the platinum sector have been on strike for over two months.
Mathunjwa said marches would expand to Lonmin next week and be followed by a march to Parliament after the Easter holidays if the union's demands were not met.
"It doesn't matter if it takes us 10 days to get there," said Mathunjwa.
He was addressing hundreds of striking mineworkers who had marched to Impala Platinum's head office in Illovo, Johannesburg, to hand a memorandum to the company.
Amcu-affiliated members working in the platinum mining sector have been on strike for over two months, demanding a minimum wage of R12 500 a month.
Mathunjwa said Amcu gave Amplats until April 5 to respond to the demands.
Amplats official Johan Theron promised to respond to Mathunjwa by the deadline.
