Difficulties at work drove teacher Leung Yuet-sheung to kill herself on Monday, friends of the woman say, in the second teacher suicide at the same Sham Shui Po school in the past four months. Police disagree, however, that Leung killed herself because of trouble at Sham Shui Po Government Primary School. They pointed to entries in her diary that showed the 43-year-old woman had emotional problems. A person who knew her said she had been taking anti-depressants. In October, a 24-year-old female teacher leaped to her death from the school building. Media reports at the time quoted a teacher's union as saying the suicide was work-related. Leung was found dead on the podium of her residential building in Kwai Chung by her husband on Monday. No suicide note was found. A police source said there was no initial evidence suggesting the suicide was related to work pressure. 'We found her diary and recent entries indicated Ms Leung had been unhappy. 'She had written that people around did not care much about her,' the source said. Fermi Wong Wai-fun, a social worker and close friend of Leung, said the teacher suffered a severe back injury at the end of September when she slipped at school. Ms Wong said her friend's death was related to the impact of an injury incurred at work and confirmed that she had been on anti-depressants. '[Leung] said the school management had made numerous phone calls implying she had faked the sick leave and questioned when she would go back to work,' Ms Wong said. 'She had been under enormous pressure, constantly worrying if the school viewed her as incompetent.' Another close friend, James Hon Lin-shan, agreed Leung had been under pressure following the injury. 'Ms Leung was a senior teacher and very passionate about her work. She even volunteered to take calls for the union's hotline counselling fellow teachers for workload problems,' Mr Hon said. Education lawmaker Cheung Man-kwong and Civic party lawmaker Audrey Eu Yuet-mee expressed concerns over the incident and called on the community to take work-related pressures of teachers more seriously. Ms Eu urged the government to increase funding for schools so they could hire assistants to lighten teachers' workloads. An Education Bureau spokeswoman said educational psychologists and counsellors were sent to the school on Wednesday and Thursday to address the emotional needs of teachers and students.
