African National Congress (ANC) secretary general Gwede Mantashe warned trade unions on Thursday against public attempts to push the government to give in to demands.
"You are projecting the [President Jacob] Zuma leadership as weak and indebted to various constituencies," Mantashe told a National Union of Mineworkers (NUM) congress in Johannesburg.
Some trade unions were creating the impression that "the ANC must react instinctively to demands", said Mantashe.
He cited a protest by the National Union of Metalworkers of South Africa (Numsa) to the South African Reserve Bank offices in Pretoria on Wednesday as an example.
"I am not sure the Numsa march was helpful," said Mantashe.
Mantashe said the Reserve Bank would not want to be perceived as having buckled under pressure from unions if it decided to drop rates.
"It is not a household tactic to march because you are actually pushing them not to drop rates," said Mantashe.
