Cabinet has urged protesters and strikers to refrain from violence.
The right to strike should be exercised in a non-violent manner, acting government spokeswoman Phumla Williams told reporters in Pretoria on Thursday, following the executive's meeting on Wednesday.
"Cabinet emphasises that such a right must be exercised in a non-violent manner and in full compliance of the law," she said.
"There is a responsibility on trade union leaders, employers, the state, and the security services to ensure that the law is upheld and that provocative actions are avoided."
Various economic sectors in South Africa, including the mining, construction, and automobile sectors, are currently engaged in wage negotiations.
Regarding the state of three South African soldiers injured while on a United Nations mission in the Democratic Republic of Congo, Williams said she did not have an update.
"South Africans are called upon to support and give recognition to these soldiers who are instrumental in realising South Africa's commitment to peace, stability, and the strengthening of democracy in Africa."
She referred questions to the South African National Defence Force.
