Johannesburg - The Nelson Mandela Bay municipality, in the Eastern Cape, has given striking truck drivers until Thursday to return to work or face action.
"The action by the employees means no domestic waste, trade waste collection services rendered since yesterday [Tuesday]," municipal spokesperson Kupido Baron said in a statement on Wednesday.
He said the municipality reserved its right to take legal action if the drivers did not report for duty.
Kupido urged residents to keep their refuse bags until the next collection date or to dispose of them at their nearest landfill sites.
The truck drivers from the Uitenhage, Despatch, Motherwell, Struandale, Gail Road and Harrower Road depots downed tools on Tuesday.
It was not known what triggered the strike.
