More than 1,000 teachers from mainstream high schools in Yunfu, Guangdong, went on strike and staged a sit-in in front of the municipal government offices in protest against poor pay. Teachers occupying the building's forecourt on Tuesday complained that, amid severe inflation, their monthly salary was 1,300 yuan (HK$1,426), a third of the amount counterparts from key high schools received for the same workload. The strikers said a junior teacher from such a high school earned 3,000 yuan a month and qualified for another 1,000 yuan in government subsidies to help offset inflation. But the protesters said they were eligible for only 50 yuan each in inflation-beating subsidies. Several protesters said authorities sent police to break up the rally and some teachers were detained over the demonstration. 'Police officers also guarded high school entrances, preventing more high school teachers from joining the sit-in. The educational watchdog arranged an emergency meeting with head teachers, and all high school teachers are required to sign in every half hour,' a blogging teacher wrote. The teacher said education authorities were willing to compromise by raising teachers' pay by only 100 yuan a month. All teachers on strike came from the city's Yuncheng district, which has 10 high schools and 2,000 teachers. A district official estimated that 25,000 students were affected by the strike. The Yunfu Education Bureau said yesterday all teachers were back at work. But some teachers said they were still on strike. Pay worries among kindergarten teachers also prompted 400 teachers from 22 kindergartens to protest in Shenzhen on Tuesday. They feared their salaries would be cut after 22 kindergartens were sold to private companies by the Shenzhen government. Mainland media reported that 10,000 children were affected by the strike.
