Teachers union Sadtu wants all schooling to be suspended with immediate effect.
The union announced this at a virtual press briefing on Tuesday.
Last month, grades seven and 12 resumed classes; early this month grades R, six and 11 also returned to school.
“The NEC, upon receiving all provincial reports about the dire state of the system on the ground, thus took the decision to call on the DBE to suspend all schooling activities with immediate effect until the peak of the pandemic rescinds,” said secretary-general Mugwena Maluleke.
Maluleke added that one of the reasons the union was calling for schools to be suspended was because it believes there has not been effective teaching and learning since the first grades returned in June.
He said this was because of schools closing when there are positive cases, as well as high levels of absenteeism from learners whose parents have decided to keep them at home.
