Susan, a 36-year-old maid from the Philippines, works at her employer's house in Singapore April 29, 2008. About half of Singapore's 170,000 foreign maids do not have a rest day according to the Unitied Nations Development Fund for Women (UNIFEM). Maid agencies in the city state fear an exodus, as offers of twice the pay and a compulsory day off lure its maids overseas, the local Straits Times newspaper said on Monday.
