Bloemfontein – A Free State teacher who was declared unsuitable to work with children should not be allowed to teach again, the South African Democratic Teachers Union said on Monday.This was after Lenard Mac Kay, who displayed a picture of Julius Malema alongside a monkey, was employed by the Trompsburg Primary School, despite a recommendation by the SA Human Rights Commission (SAHRC) that he never work with children again.The school confirmed to News24 that Mac Kay started teaching there last week, but that it was on a temporary basis."We are unhappy that he is back at work, despite recommendations that he is unfit to work with children and we want the department of education to deal with this," Sadtu Free State secretary Mokholoane Moloi told News24. "The department cannot allow the same person to teach at public schools. We cannot keep quiet when such things happen," Moloi said."The department is being soft on this case. They should follow the recommendation of the Human Rights Commission so that the teacher doesn't work with children anymore."Mac Kay lost his job at Wilgehof Primary School in Bloemfontein in 2013 after he used the k-word and displayed a picture of Economic Freedom Fighters leader Julius Malema alongside that of a monkey in his classroom.The SAHRC conducted an on-site inspection of the school following a complaint from a parent.In October that year, the SAHRC found him guilty of racism and hate speech.On July 1, 2015, he got a job at the Dr CF Visser Primary School.He left after the education department objected and asked the school's governing body not to employ him.
