Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
The Food and Allied Workers Union (Fawu) has vowed to intensify its strike if Noord Wester Koporasie (NWK) in Lichtenburg, North West, does not bow to its demands.
Fawu's vice president, Elizabeth Manoto, said the union would seek support from Cosatu, the Communist Party and other organisation to help it bring the management of NWK to the negotiation table.
"We will call on our entire comradeship to help us to boycott all NWK products," said Manoto.
The strike started last week, following a deadlock between the union and the maize producing company.
Fawu said the company's management had offered members of the Solidarity union a 7,5percent salary increase but had refused to give Fawu members the same increase.
Solidarity is the majority union at NWK. Fawu has 750 members there.
The strike has entered its second week, but NWK's management seems not to be bothered by it.
According to NWK's senior managers, the Fawu strike has not affected the company.
"As far as we can tell you, everything is normal except the noise you hear from outside.
"Our production is excellent and we cannot complain," said a manager who refused to be identified.
