Civil service unions yesterday made a united call for an across-the-board pay rise of 6.9 per cent. The Senior Non-Expatriate Officers' Association, the Model Scale One Staff Consultative Council and the Junior Police Officers' Association agreed on the proposal to be put to the Civil Service Branch. The pay trend survey, used to set civil service pay, showed the rise for the private sector for the last financial year was 6.9 per cent, 6.81 per cent and 6.38 per cent for the upper, middle and lower ranks respectively. Hui Kwok-hung, non-expatriate association chairman, said the demand had been made because 'the livelihood of the lower rank staff has been difficult'. 'The pay trend indicator for the lower rank is lowered due to the lower pay of imported labourers,' he said. The unions are demanding talks with Chief Secretary Anson Chan Fang On-sang.
