Johannesburg - The 2011 election results reflected South Africa's "apartheid, racial and semi-colonial economy and society", the National Union of Metalworkers of SA said on Wednesday.
"We reject the false language and false analysis of the type 'minorities did not vote for the ANC'", said Numsa's national executive committee in a statement.
"The scientific truth is that these elections perfectly mirror the untransformed apartheid spatial, racial and semi-colonial economy and society of South Africa, notwithstanding the 1994 democratic breakthrough."
Numsa would look into using the ward demarcation process to undo the "artificial and racist spatial distribution of resources".
"We will demand that time has come to combine the centre and periphery located wards into integrated wards.
"After all, in the last elections the party of white monopoly capital sent a clear message that white capitalist in South Africa are now ready to kiss and live side by side with their black and African fellow human beings"
The union would demand that the development of mixed-income settlements be set up across the country to ensure that workers were spared from huge transport bills by living closer to their workplace.
Numsa's leadership body congratulated the ANC for its success in the election.
It recognised the "deeply entrenched" nature of the "racist capitalist system" in the Western Cape.
"...The NEC of Numsa is convinced only a truly full blooded assault on the racist capitalist system in South Africa in general and in the Western Cape in particular will truly unite the majority of the working and middle class behind the revolutionary programme to transform this country into a truly non-racial, non-sexist, classless and democratic society."
The union slammed the Democratic Alliance for claiming to be the "true bearer" of the values espoused by former president Nelson Mandela, saying the opposition party "mocked the ANC".
"It spat on the Freedom Charter.
"It made poor working class crowds to sing revolutionary songs for a white male dominated capitalist party. And it took away a small but significant vote from the ANC," the statement read.
Numsa reiterated its stance on labour brokers, demanding that they be abolished.
