MORE than 20 workers were hospitalised on Tuesday and Wednesday after fainting on the job at the M&V garment factory in Kampong Chhnang province, a union representative said. Choub Samol said officials from the provincial environment department had investigated the factory after the fainting spell and concluded that it was caused by the workers’ poor health. A provincial labour department official offered a similar explanation when nearly 200 workers at the factory fainted last month. But Choub Samol said he believed chemicals at the factory were to blame.
