THE Government had no obligation to formulate legislation to protect workers' right to strike, despite the provision of it in several international agreements, said Attorney-General Mr Jeremy Mathews. Responding to a question from United Democrats leader Mr Martin Lee Chu-ming, Mr Mathews said: ''The obligation under international treaties is not interpreted by the British Government as to mean that contracted parties are obliged to form legislation conferring the right to strike.'' The Government is not violating the agreements as long as it does not impose legislation to stop workers from going on strike, he said. When asked by Mr Lau Chin-shek whether the ''right to strike'' was provided, Mr Mathews said the term was not a common phrase used in English law. His comments came two weeks after the Education and Manpower Branch began a review of the handling of the Cathay Pacific labour dispute. Mr John Chan Cho-chak, the Secretary for Education and Manpower, agreed to consider the suggestion of freezing employment contracts during strikes to prevent unfair dismissal. He also agreed to take note of Mr Yeung Sum's suggestion about the amendment of the Employment Ordinance regarding the formation of trade unions. But he refused to make any promises before the report was completed. He said the study would try to strike a balance between the interests of employers, employees and the public. He said the review would cover both the legal structure and the enforcement of law.
