More than 1,000 dumper truck drivers staged a strike yesterday demanding that contractors pay a fuel surcharge. About 70 dumper trucks lined up in Wan Po Road, blocking one of the lanes leading to the entrance to the Tseung Kwan O landfill at about 9am, while two dozen dumper trucks were driven to landfill sites in Tuen Mun and North Point in support of the industrial action, which ended at about 5pm. The Hong Kong Dumper Truck Drivers' Association, which has about 1,600 members, is demanding that contractors pay a fuel surcharge of HK$30 for journeys of less than 30km and HK$50 for journeys of more than 30km, with the rates adjusted every three months. The association's chairman, Lee Chi-fai, said although only about 100 trucks were at the three landfills, he believed more than 1,000 drivers stopped work. Association representatives would meet the Development Bureau today, Mr Lee said. 'We hope we will hear some good news in the meeting, then we can all go back to work.' The association planned to hold a week-long strike, but some positive news has been received from some contractors and the industrial action might be shortened. 'We will review the situation on Tuesday to see whether we will continue our strike or get back to work, as some contractors have agreed to pay the surcharge,' Mr Lee said. The price of diesel, before tax, has risen from HK$7.45 a litre to HK$10.11 a litre in the past year. 'Expenses on diesel used to count for 30 per cent of our operating costs, but now it is over 60 per cent. We really cannot bear this anymore and developers and contractors should cover the extra cost,' Mr Lee said. The association estimated that about 30,000 tonnes of waste had accumulated at all construction sites in the city due to the strike. The secretary general of the Hong Kong Construction Association, Thomas Tse Che-wah, said it was concerned about rising diesel prices, which had increased the operating costs of the drivers, and urged drivers to be rational. 'Drivers should negotiate with the subcontractors directly on the service charges under the market mechanism, should they wish to seek compensation when the operating costs increase,' he said.
