The agreement will avert a repeat of last year's strike that left hundreds of dry pumps across Africa's biggest economy.
Solidarity said in a statement on Tuesday the deal includes an 8% pay rise for 2012 and a consumer price index (CPI) plus 2% increment from April 2013.
Solidarity said the agreement for next year was on condition that should CPI drop to below 5%, the raise would not be below 7%. Should inflation rise above 8% then the wages would be raised by not more than 10%, it said.
Sasol, PetroSA and Engen are some of the biggest employers in the sector. – Reuters
