A cook who claims Financial Secretary Donald Tsang Yam-kuen owes him $70,000 in overtime pay told a tribunal yesterday how he was friendly with his former boss but unhappy about his working conditions. Yu Yin-ping complained he found himself in an awkward situation within minutes of beginning a 10-month stint as the $15,000-a-month head chef at Mr Tsang's official residence in Wong Chuk Hang in December 1999. 'I was told by the Administration Office after I was hired that the residence would provide me with all my personal daily necessities such as pillows and eating apparatus,' he told the Labour Tribunal hearing. 'But when I arrived, I found it wasn't the case and the housekeeper had to arrange a car to take me to town to make some quick purchases.' He said he worked far longer than the stipulated 44-hour week, had to clean the kitchen by himself and make Chinese herbal medicine. Furthermore, Mr Yu claimed he was often unable to take days off when Mr Tsang was out of town as he had to stay in for repair men. Mr Yu, however, said his discontent did not prevent him establishing a close, friendly relationship with his employers. 'For example, Mr Tsang and his wife would ask me about my family and they were very interested to learn how my son was doing in school,' he said. However, executive officer Ang Ming-mei, who hired the chef, told the tribunal: 'I felt very pressured by numerous phone calls made by him regarding his complaints over working hours. We wanted to help him in any way we could but he kept repeating the same accusations that he had been doing extra work unrewarded without giving us written proof . . . to back up his complaints.' She said Mr Yu, now unemployed, had turned down extra days off as compensation. Presiding officer Lambert Lee adjourned the case to May 21.
