Migrant workers marked Labour Day by organising a day-long rally against discrimination and exploitation. 'Migrant workers in Hong Kong have been the objects of various anti-migrant, discriminatory and racist attacks, especially since the 1997 economic crisis,' said the Coalition of Migrant Rights in its International Labour Day manifesto. It said that foreign domestic helpers had been subjected to a wage freeze and wage cuts in the past two years. The coalition also criticised recent proposals - from removing maternity protection to imposing service tax for the use of public facilities - as discriminating against migrant workers. 'Their benefits, such as maternity and other health matters, are sometimes not respected,' said Sajida Ally, the coalition's networking and advocacy co-ordinator. She said that apart from the Filipinos, a large number of Indonesian, Thai and Indian domestic helpers were being underpaid. A recent study showed one in two Indian domestic workers receive wages below the minimum level. A Filipino domestic helper, 30, identifying herself as Janet, complained of lack of privacy due to supervision by her boss. 'They are out of town for 10 days now, but have a relative living in the house watching my every move. I cannot understand why it's necessary. I do all the work every day,' she said. Another Filipino, Evelyn Macay, 30, was sacked when she did not want to also work at the home of her employer's mother-in-law. 'The following day, after I complained, she told me to pack up and go. This is all very unfair,' she said. Migrant workers' groups from the Philippines, Indonesia, Thailand, India, Sri Lanka and Nepal as well as some other organisations make up the coalition. The migrant workers gathered in Victoria Park and marched to Southorn Playground in Wan Chai with the Confederation of Trade Unions. About 180,000 migrant workers are employed in the SAR, mostly from South and Southeast Asia.
