DOMESTIC workers have demanded to know more about government plans to impose new identity cards on them. They say the move is discriminatory and part of an overall plan to discourage foreign employment. The Immigration Department is considering changes to foreign domestic helpers' ID cards, as part of a number of measures aimed at controlling illegal immigration. 'We will also consider requiring all contract workers, including foreign domestic helpers, to surrender their identity cards to the Immigration Department for cancellation on their departure at the end of their contracts,' said a policy document supporting the Governor's address. A spokesman for the department said the changes would make foreign domestic helpers' ID cards easier to distinguish. 'Some specifications would enable easier identification of their status,' he said. 'Details are being worked out.' Any new measures, including the requirement to surrender cards, were subject to legislative amendment. Remy Borlongan, chairman of the Asian Domestic Workers' Union, said: 'We already have a different ID card than everyone else, so why the change?' 'We have just had a meeting with the Immigration Department this week and they didn't tell us anything. Once again we have not been consulted or even informed.' Ms Borlongan said it was another form of discrimination. 'I thought Hong Kong was a free society. Maybe this is in preparation for expected changes in 1997,' she said. Domestic workers are already fighting the Government over its refusal to grant a minimum wage increase. Betty Yung Ma Shan-yee, chairman of the Hong Kong Employers of Overseas Domestic Helpers, welcomed the ID card idea. She said it would help prevent fraud, where lost or sold cards ended up in the hands of illegal immigrants.
