Amplats workers were downing tools to force the firm to reconsider 3300 retrenchments at its South African operations, Amcu said on Tuesday.
The strike was scheduled to begin on Friday morning.
“All we are looking for is to ensure the members taking part in the strike [get] to exercise their democratic right but also respect the rule of the law,” police spokesman Brigadier Thulani Ngubane said.
Police drew experience and confidence from the Marikana commemorations in August, which marked the deaths of 44 people during a strike at Lonmin’s Marikana mines last year, where all parties co-operated, he said.
“We have to be ready at all costs. The police are supposed to be ever ready,” said Ngubane.
“We are ready. Our role will be to monitor the situation and they know what is expected of them. It is not us, but the laws of the republic.”
