Anson Chan Fang On-sang has been warned of another mass protest by civil servants if she snubs staff fighting unpopular management reforms. The warning to the Chief Secretary for Administration came as unionists vowed to push ahead with plans to form an alternative federation which they say will be more outspoken in defending staff interests. Unionist Wong Wai-hung, who led a 10,000-strong march against the civil service reforms on July 9, said Mrs Chan had merely acknowledged receiving a petition of 40,000 signatures in a reply through an aide on July 11. The coalition of 18 staff unions has demanded Mrs Chan provide 180,000 civil servants with an undertaking there will not be further measures eroding staff benefits. Unionists are to discuss follow-up action at a public forum next Friday. 'I think we can at least organise a much bigger street protest to air our grievances. The pressure on the Government will be huge,' said Mr Wong, head of the Association of Government Land and Engineering Surveying Officers. At least 10 of the 18 unions, covering about 10,000 staff, were keen to initiate another cross-agency body. 'Unlike other federations, we will have concrete actions,' he said.
