The National Union of Metalworkers of South Africa (Numsa) and other trade unions took to the streets in Cape Town on Thursday to protest against police brutality and low wages.
The workers and trade union leaders accused President Cyril Ramaphosa and his administration of being more concerned about the interests of big corporates other than their own.
The ongoing protests have been characterised by clashes with the police.
Earlier this month, four people were arrested after an unruly protest outside Dis-Chem in Canal Walk shopping centre in Cape Town.
