The specific group of large-scale migrants this paper focuses on is female, live-in domestic workers who migrate from the rural villages of Thailand to work in wealthy urban homes. Domestic labour offers employment in the informal sector, an invisible form of labour exploitation perpetrated by the urban wealthy on economic migrants. Limited information is available on the migrants’ earnings and working conditions, which allows exploitation to continue. This paper investigates the root causes of this migration that directly affects both local and national economics. It suggests possible solutions for government to encourage and support communities to set up organizations providing assistance to this powerless group of women.
