After the murder, the department's district officials promised to deploy security guards. This has allegedly not happened.
Yesterday teachers left pupils stranded after handing letters of resignation to the principal.
National Teachers Union official , Xolani Mthethwa, said he has had a number of meetings with the teachers in which he pleaded with them to continue teaching for the sake of the pupils.
"The teachers claim the hijackers have threatened to return to harm them," he said.
Mthethwa advised the teachers to follow procedure and apply for transfers if they felt that their lives were in danger.
"The procedure is that in the case of intimidation, a teacher has the right to apply for a transfer, but must report to a local circuit office daily," Mthethwa said.
He said teachers were willing to teach if the department deployed security guards at the school.
