Unless drastic action is taken to reduce unemployment, South Africa may face another 1976 uprising, Cosatu general secretary Zwelinzima Vavi said. 'I have already over and over again pointed out the danger of a ticking bomb, that unless we can do something drastic about the crisis of unemployment, in particular youth unemployment, we risk another 1976 uprising,' he said in a speech delivered in Johannesburg. He was speaking at a discussion themed 'Critical conversations on prospects for a non-racial future in SA'.
