At least 18 people have been detained and 10 injured in the past two days after a show of force by police to end a workers' protest in Shenzhen. About 400 workers at the Eltop Electronics Factory, owned by Taiwan's BAFO Technologies, have been on strike since May 21 in protest over unpaid wages and redundancy packages. The factory announced last month that it would relocate to Dongguan at the end of this month. A witness said about 200 police officers and uniformed security guards raided the factory on Monday and yesterday, when hundreds of employees surrounded trucks carrying equipment and products into and out of the facility. 'The police hit the workers when we tried to stop the trucks. At least 10 workers were injured and sent to hospital on Monday,' one protester said yesterday. 'The police and security guards came and clashed with our workmates again this afternoon. They even came to the hospital and detained all of the injured.' The worker said the protest was aimed at drawing attention to inadequate compensation paid to workers facing redundancy because of the closure. Only 218 of 800 employees would have jobs at the new factory. 'We called [the police on] 110 and the local labour bureau for help several times. I didn't expect we would be beaten by the police,' the worker said. The workers complained that the redundancy packages were well below the minimum compensation standards set out in the labour law. Since late last month, the dissatisfied workers have staged a sit-in outside the factory and formed two shifts of guards to stop management moving out factory equipment. 'Many workers have been working for the factory for more than five years. The management paid us only 100 yuan in compensation for each year of service to the company,' the worker said. 'I have spent over 10 years doing this. But I got only 1,000 yuan compensation at the end. That's very unfair.' Management later raised the payouts to 350 yuan for each year of service but the workers still refused the offer. He said they asked for a minimum of one month's salary for each year of service. The workers said they would keep surrounding the factory and continue their protest until their demands for better compensation were met. A representative from the company was not available for comment yesterday. Similar protests have broken out in Shenzhen in recent years as Hong Kong and Taiwan raw-materials processing businesses have been asked to move out of Shenzhen to cut pollution in the city. In January, hundreds of Shenzhen workers employed by Italian sofa-maker DeCoro protested outside the company's factory after three colleagues were badly beaten by security guards for demanding better severance payments. The workers said the company wanted to sack 75 of them and offered them substandard severance. In February, more than 200 workers protested against the closure of a Shenzhen factory that made Disney souvenirs, which they said left 800 workers jobless and without compensation.
