Almost 50 workers at the Ging Ko 2 garment factory in Svay Rieng’s Bavet town fainted on Saturday, a union representative said.

Pav Sina, president of the Collective Union of Movement of Workers (CUMW), said the fainting at the factory in the Tay Seng Special Economic Zone began in the morning when several workers collapsed. Another 40 fainted after lunch.

“The workers are feeling better now and have left the medical clinic,” he said yesterday. “But we still don’t know what caused the fainting. I think it might have been the hot weather, not enough air in the factory and weak health due to a lack of good food.”

Those who fainted had been sent home and will return to work today, Sina said.

Ging Ko 2 factory officials could not be reached.

Earlier this month, the Ministry of Labour reported that more than 600 workers had fainted on factory floors since January 1, compared with about 823 recorded for the whole of last year.
