Nearly 1,000 workers at an electronics company in the northern city of Hai Phong started a strike Monday after their South Korean employer reportedly ignored their requests for cutting working hours and increasing wages.

The workers at Bluecom Vina, a South Korea-invested company, said they also want the company's management to recognize their right to form a union as promised , local media reported.

According to the workers, the company which produces TV speakers and earphones does not have official working hours.

Workers have to start working from 8 a.m. until the managers decide that they can leave, which is usually 9 p.m. or 10 p.m., even on Saturday.

But the workers are only paid VND3,745,000 (US$165) a month. The extra hours are not fairly compensated, with the company only offering to pay VND100,000 ($4.50) for all the extra hours accumulated in the month.
