No reply a week after complaining to the government about their principal Teachers at an Aberdeen school are frustrated that no action has been taken a week after they complained to the Education and Manpower Bureau about their principal, who allegedly told them to shun a 13-year-old pupil confined alone for five months. They said neither the bureau nor the school sponsoring body had told them whether or how they would follow up their complaints that Form One student Chan Sin-ting was kept isolated in a computer room at Po Leung Kuk Wai Yin College between November and June. 'We had a staff meeting today in which we were told by the vice-principal that we could complain to a school-based management committee chaired by the principal if we were dissatisfied with any school-related matters,' one of the teachers said yesterday. 'But how can we complain to the group about the principal? It would just be like complaining to the Chief Executive Tung Chee-hwa about himself.' Last week nearly half the school's senior teachers brought to the bureau's regional education office concerns they have over the principal, Cecilia Yeung Mi-kuen. They claim she ordered them not to help the girl, frequently scolded staff, treated students unfairly and censored meeting reports. Last Thursday, Mak Kwai-po, principal education secretary of Po Leung Kuk, the school sponsoring body, told the South China Morning Post that he would meet all the teachers individually this week to investigate the complaints. But the teachers said yesterday they had not been notified of such meetings. The teachers last week gave the Post a tape of a staff meeting held at the school in June. A voice, which they said was that of principal, was heard instructing them not to help the girl, saying if they did, there was a risk that she would want to stay at the school. The voice also said that the student could not control herself without medication. The principal denied all the allegations last week. Meanwhile, the bureau reiterated its position not to take any action until the Po Leung Kuk had finished its investigation. 'If we have problems with the sponsoring body's judgment, we will follow up,' a bureau spokesman said. But the bureau's response was criticised by the teachers and Cheung Man-kwong, the legislator who represents the education sector. Mr Cheung said: 'The ordinance on school-based management states the government has the [obligation] to ensure that every child receives proper education. 'School-based management does not mean that a school or school sponsoring body can be treated like a court and can have the final say on all matters.' He urged the bureau to conduct an independent and fair investigation into the complaints and said the teachers were welcome to complain to the Legislative Council.
