Labour officials are still trying to track down the owner of a restaurant which closed on Monday, leaving workers with two months of unpaid wages. About 45 employees of the Royalty Restaurant in Shau Kei Wan have sought help from the Labour Department to locate their boss. Notices posted at the restaurant said it would be closed for three days due to electrical problems. It was still unknown whether the owner was unwilling or unable to pay the workers, said a spokeswoman for the department. 'We cannot be sure how much the restaurant owner owes the workers until we track down the owner,' she said. Another restaurant which also closed down on Monday, the Fook Sing Restaurant, is believed to owe 166 staff a total of at least $1.9 million. The directors of Fook Sing Restaurant will meet the workers to resolve the issue of unpaid wages on Friday and Monday. Meanwhile, the department has contacted the director of a third establishment, the Hang Ho Restaurant, which folded its four outlets last month. It has referred the case to the Legal Aid Department. 'The restaurant owner has admitted that he cannot pay the workers. The Legal Aid Department is in charge of the case, and will help the workers retrieve compensation and salaries by applying for a winding-up order,' the department spokeswoman said. The three-year-old chain shut branches in To Kwa Wan, Tsuen Wan, Shek Tong Tsui and North Point last month, leaving more than 200 staff with unpaid wages of at least $3 million. The Labour Department has set up two hotlines to help workers understand their rights. Workers can call 29294065 or 21585553.
