Public hygiene officials have vowed to investigate a report that a street-cleaning team spent only 83 minutes performing their duties on one day and took a two-hour lunch break. The case, reported by a newspaper yesterday, emerged only days after an Audit Commission report condemned the Food and Environmental Hygiene Department for allowing staff to be idle during working hours, costing the Treasury $11.7 million. According to the Ming Pao Daily News, the team of one driver and four cleaners was observed spending less than 70 minutes cleaning a street in Kwai Chung and 14 minutes in Tsing Yi during their eight-hour working day on Tuesday. The rest of the time they reportedly sat in the cleaning truck and let the automatic water-jet do the work. In between, the team spent one hour 50 minutes in a government canteen for lunch, the newspaper reported. A spokesman for the department said an investigation had been launched into the alleged misconduct. He said none of the 200-plus street-cleaning staff had been disciplined or sacked over the past four months for misconduct. After receiving the commission's report, the department had drawn up measures to address any problems, he said, but refused to reveal details. Officials will attend a Legco Public Accounts Committee hearing next week on the problem. Secretary for Civil Service Joseph Wong Wing-ping said department heads should punish lazy staff, but declined to say whether there had been a lack of monitoring by the department.
