Labour Minister Mildred Oliphant says her department is ready to mediate in the farmworkers' strike if all parties return to the negotiating table,
Oliphant's statement came after the Congress of SA Trade Unions in the Western Cape announced that farmworkers would intensify their strike today.
The farmworkers were also rejecting a call by the ANC for the suspension of the strike.
Cosatu Western Cape secretary Tony Ehrenreich says negotiations with some farmers have shown progress, and that if agreements are reached with farmers in particular areas, the strike will end in those areas.
Farmworkers are calling on Oliphant, Trade and Industry Minister Rob Davies, Economic Development Minister Ebrahim Patel and President Jacob Zuma to intervene in the strike.
