Johannesburg - Hundreds of National Union of Metalworkers of SA (Numsa) members gathered at Zoo Lake in Johannesburg ahead of their march on Wednesday.
“Ulimenemene Jacob Zuma (President Jacob Zuma, you are two faced),” they sang.
Others blew whistles while some women ululated.
One man wound a siren that blasted through the area.
The marchers were dressed in the union's signature red tops.
A few in the crowd wore red Economic Freedom Fighters T-shirts and berets.
The march for jobs was expected to proceed to the National Economic Development and Labour Council (Nedlac) premises in Rosebank.
A few police officers were positioned at the entrances to the area.
A Numsa official called for discipline, saying the police were not there for their protection.
“You know what they are here for,” he said over a microphone.
Some marchers carried placards reading “Living wage for all now”. Others placards proclaimed “Smash false solutions”. - Sapa
