The Government's attempt to freeze seven ordinances through an 'umbrella' bill yesterday faced a serious challenge as more members threatened to vote it down. Chan Yuen-han of the pro-China Federation of Trade Unions vowed to vote down the Legislative Provisions (Suspension of Operation) bill if she failed to save two labour ordinances from the proposed suspension. Ms Chan, whose federation has three votes in the provisional legislature, said she would move amendments to the bill, seeking to delete the Occupational Deafness (Compensation) (Amendment) Ordinance 1997 and Employment (Amendment) Bill Ordinance 1997 from the list of seven laws proposed for suspension. The former strengthens the protection of employees against anti-union discrimination while the latter relaxes the disability requirement for compensation under the Occupational Deafness Compensation Scheme. Ms Chan's warning came after she made an abortive attempt to get the Government to separate the seven laws contained in the 'umbrella' bill into seven bills. Ms Chan said the federation had yet to decide on whether to support the proposed suspension on two other laws. They are the Employment (Amendment) (No 5) Ordinance 1997, which makes May 1 a statutory holiday, and the Trade Unions (Amendment) (No 2) Ordinance 1997, which seeks to relax controls over the activities of trade unions. While maintaining that the federation supported the spirit of collective bargaining, Ms Chan said it would support the freezing of the bill which gives employees' the right to collective bargaining. This would enable a better deal to be found on the issue, she said. The Association for Democracy and People's Livelihood said it would vote down the all-encompassing bill. James Tien Pei-chun of the Liberal Party said the party would support the freezing of all seven laws but would oppose them should the bills return to the interim body in any form. Secretary for Education and Manpower Joseph Wong Wing-ping assured members that the administration would complete the review of the bill by September 30 and consult the provisional legislature on the outcome.
