Disciplined services unionists yesterday urged an urgent review of the performance appraisal system. The 4,000-strong Government Disciplined Services General Union finalised its position on the civil service review with a call to overhaul the long-standing appraisal system. 'The current system is peppered with loopholes and is prone to control and abuse,' union secretary Chan Kwai-keung said. Mr Chan said some departments used only appraisal records to determine promotion. 'This could be subjective and affects promotion. The issue should be given top priority in the reform,' he said. The union suggested disclosing all appraisal results of the same rank to improve openness and objectivity. Members also rejected proposals to award performance-based pay. 'The lack of objective assessment criteria means pay adjustment would be unfair,' Mr Chan said. The union also firmly rejected plans to replace permanent appointment with contract terms, saying stability of the disciplined services would be undermined.
