The new head of the Equal Opportunities Commission kicked off her first day in the post yesterday with a resounding silence. Women's groups said they were worried that chairman Fanny Cheung Mui-ching had failed to take up the case of female staff at Lippo Securities who were told they would be fined $300 every time they turned up for work in trousers. Ms Cheung refused to comment on the case today. Officials said her first day itinerary included meetings but refused to elaborate. The Lippo case was 'precisely the kind of situation the Equal Opportunities Commission should be looking into', said Lam Wai-ha, of the Association for the Advancement of Feminism. 'The least she could do is to make some kind of comment about the attitude. We are quite disappointed,' she said. Linda Wong Sau-yung, director of the Hong Kong Federation of Women's Centres, said: 'It's the duty of the Equal Opportunities Commission to handle these kinds of issues and do something in this case.' Ms Cheung earns $157,250 plus a monthly bonus of $70,320 for heading the commission. It aims to eliminate discrimination on grounds of sex or disability and promote equal opportunities.
