Laid-off employees of the surveying firm run by Housing Society chief David Lee Tsung-hei complained to police yesterday after he missed an arbitration meeting. Legislator Lee Cheuk-yan, who is helping the workers, said the Commercial Crime Bureau had accepted their complaints but needed more evidence before deciding whether to investigate further. He said the workers suspected the liquidation of the firm, David C. Lee Surveyors, could involve a questionable transfer of assets. The complaint deepened the woes surrounding David Lee, who is embroiled in a legal dispute with a board member and is facing calls to resign as chairman of the society, a provider of subsidised flats to the needy. David Lee, in a statement issued through a public relations firm later, denied that the liquidation - applied for last week - was a tactic to avoid paying wages. He said the firm still had $4 million in construction fees to collect. Once a creditors' meeting had been held and the fees collected, staff could claim the unpaid wages, he said. A creditors' meeting is scheduled for June 19. More than 120 staff have been laid off, leaving an estimated $4 million to $5 million in unpaid wages, pay in lieu of notice, holiday pay and bonuses. Forty-seven staff attended the labour relations meeting mediated by the Labour Department yesterday. A department spokesman said it had invited David Lee, but as the liquidation process had already started, only temporary liquidators attended. Staff representatives claim the liquidation is suspicious because the company had earned a profit of more than $3 million from November to April, just in its building surveying department, and employees had been promised $1 million in bonuses. But according to the temporary liquidators, just $400,000 is left in the company. 'I don't understand where these profits have gone,' Lee Cheuk-yan said. 'This is very mysterious.' Changes in the board of directors last month were also 'very suspicious'. The Employment Claims Investigation Division of the Labour Department would also start an investigation, he said. Staff representative James Law Sheung-ping said staff had already started a firm to take over contracts worth a potential $10 million from their former employer and were 'extremely disappointed' by David Lee's absence and questioned his credibility. Next Monday, the staff members would apply for legal aid and to the Protection of Wages on Insolvency Fund for their unpaid wages and severance payments.
