Johannesburg - After 20 years of democracy in South Africa it is clear that capitalism has failed, National Union of Metalworkers of South Africa (Numsa) president Andrew Chirwa said on Sunday.
"We are here because we want to change the world in favour of the working class," he said.
"We want to destroy capitalism... Capitalism has failed."
Chirwa was speaking at Isando in Kempton Park on the East Rand at the official opening of a week-long Numsa political school.
The political school would be attended by 150 shopstewards and other Numsa activists.
It was aimed at taking forward the resolutions adopted at its December Special National Congress.
Chirwa said the union gathered because it wanted to destroy capitalism.
He said Numsa would not look back on its resolution in December that President Jacob Zuma had to resign with immediate effect because of corruption and the policies his administration were implementing.
The union also resolved to not support the African National Congress in the upcoming elections.
Chirwa told the political school on Sunday that they had received support for their call for Zuma to resign and could not look back.
"The hope of the poor and vulnerable is in our hands -- we can't look back now," he said.
"The political school will help strengthen us more."
He said Numsa had been inundated with requests by workers across different sectors to join the union.
