The violence that broke out during the Democratic Alliance (DA)’s Youth Wage Subsidy protest is a sign of growing rage that the poor feel towards the rich, Cosatu General Secretary Zwelinzima Vavi said on Wednesday.
He was speaking at a three-day international policy conference in Kempton Park.
Vavi said unemployment, coupled with dehumanising poverty, is a ticking time bomb waiting to explode.
He said South Africa was faced with high levels of inequality.
On Tuesday morning, DA and Cosatu members clashed in the Johannesburg CBD.
Coastu members allegedly threw rocks at DA protesters, who hurled objects back at union demonstrators.
The opposition party was marching to Cosatu House to hand over a memorandum in support of the subsidy.
The federation is opposed to the scheme, saying it is not a viable way to deal with youth unemployment.
