More than 100 teachers from five schools in Memot district, Kampong Cham province, have written to the Ministry of Education requesting two months’ back pay worth 64 million riels (US$15,351). Nhoung Tak Dara, of Khnong Krapoe Primary School, said the debt dates from 2008, when management of the staff was transferred to the ministry from a local rubber firm. Svay Phalla, provincial director of the education department, could not be reached for comment Tuesday.
