The labour force of the migrant domestic workers (MDWs) has become one of the significant policy concerns in Asia. Most of the Asian countries are not following (or not to an equal extent) the Domestic Workers Convention 2011 (No. 189) which has been adopted by the International Labour Organization (ILO). The objective of this article is to show the transnational variations and policy concerns of the MDWs in Asia. Based on content analysis, the authors found that there are considerable transnational variations of the MDWs in terms of their age and nature of work, legal identity, working hours, and remuneration across Asian countries. These variations have serious policy concerns in a number of areas such as lack of available data of the MDWs, working conditions, exploitations, and gender issues. The findings of the article would be an important guideline for adopting new legislation and labour policy for the MDWs in Asia.
