Twelve of the more than 2000 mineworkers who've embarked on an underground sit-in at Impala Bafokeng Platinum mine in Rustenburg in the North West - have resurfaced due to them having chronic medical conditions. The sit-in protest which began yesterday has since brought operations at the mine to a standstill. The workers are frustrated over a number of issues including employee share schemes and pension funds after the mine was bought by Impala. Sakina Kamwendo spoke to SABC reporter, Hasina Gori.
