The vast majority of migrant workers in Thailand are employed predominantly in low‐paying occupations commonly described as “3‐D jobs” (dangerous, dirty, and difficult). Currently, there are nearly two million documented and undocumented migrant workers, mostly from neighbouring Burma, Lao People’s Democratic Republic, and Cambodia, employed in various industries, including domestic service, throughout the country. While over half a million migrants are officially registered to work in the country, both documented and undocumented migrant workers remain unprotected primarily due to the lack of concrete measures to monitor, implement and enforce laws regarding working and living conditions. Regardless of where they are employed, migrant workers face common problems: low wages; harmful working conditions, poor living conditions; discrimination and harassment, the threat of arrest and deportation; and lack of access to basic resources such as medical care and legal assistance. Based on preliminary research conducted in the summer of 2005, this article looks at the situation of migrant factory and domestic workers in Thailand and explores the ways in which local activists, NGOs, community‐based organisations, and international bodies have been looking to assist and protect migrant workers. Successful migrant workers’ struggles and ongoing efforts of mobilization have been made possible with the help of these support groups, and raise the possibility that union and NGO activity have the potential to improve the situation of migrants in Thailand. This also raises the question of whether advocacy groups should be acting in lieu of the state rather than alongside the state, especially when it appears that they are fulfilling their civic duty as enforcer and monitor of migrant workers’ problems.
