DISGRUNTLED Thai workers from the Chek Lap Kok airport construction site filed more wage claims at a temporary office set up by the Labour Department yesterday. Delegates said they would meet Thai consular officials this afternoon to discuss the row over inconsistent wage statements in their contracts. Workers say contractors have paid them substantially less than the figures stipulated on employment contracts submitted to the Government. About 20 Thai workers filed claims at the temporary office in Ng Wah College, San Po Kong yesterday, bringing the total to 740. The chairman of a Thai support group, Amphan Calixterio, said the contracts held by workers lacked a signature from consular officials. This should have been imprinted over the chop of the Thai Consulate. Ms Calixterio said one example involved the contract for a Thai concrete worker, which bore no signature from the consulate. The worker's salary was slightly more than one-third of the government-set minimum. Workers have complained that employers are deducting a further 25 per cent from salaries for food and board. Yet the conditions required six people to live in containers designed for four, and swelter without relief throughout the summer, Ms Calixterio said. 'There are no air-conditioners and some of the fans are broken. If the workers want to have fans they have to buy for themselves,' she said. '[The workers] are not allowed to watch television after 7 pm, and they are not allowed to go out at that time of night. 'The camp boss [bailiff] would come and say to them, 'What are you doing?' or 'Why are you not sleeping?' and make them go to bed.' The concept of sick leave had not been explained to the workers, encouraging them to work even when they were ill, she said. 'Even if they went and saw a doctor they would still go to work because they thought the more they rest, the more money they will lose,' she said. Food consisted of 'nothing except chicken and eggs', Ms Calixterio said. Assistant Commissioner for Labour Alfred Chan Wing-kit said his department was continuing its inquiries. 'The companies say they have followed the legal procedures but we are still investigating the issue,' he said. His comments were affirmed by the Deputy Commissioner for Labour Yiu Yan-nang. 'If we find any evidence of offences we will prosecute the companies involved.'
