Student movement, Congress of South African Students COSAS has threatened to shut down all schools, from today, that have not fully implemented strict control guidelines to combat the spread COVID -19. The movement has also reiterated its call for covid-19 tests to be made compulsory in all public schools. Last week, a group of COSAS members forcefully removed learners at various schools in Bloemfontein demanding that the safety of learners be not compromised in any way.
