Two employees at George Campbell Technical High School, in Durban, are being suspended.
This after unrest at the city centre school last week, when pupils protested against various issues, including racism.
They claimed they had been called "monkeys" and the K-word.
On Thursday and Friday, they brought teaching and learning to a halt and demanded the Department of Education address the problems at the school.
On Sunday night, Education spokesperson Sihle Mlotshwa said there had been a meeting at the school and that they had resolved to suspend a school governing body-employed teacher who allegedly called the pupils "monkeys" and another SGB employee who had allegedly assaulted pupils, pending investigations.
