The New York Times reports on the struggle to protect domestic workers, an overlooked group of 100 million people, many of them female migrant workers. Some progress has been made since an international treaty to protect domestic workers was signed in June 2011: a Hong Kong Court struck down a law that excluded domestic workers from residency rights, and regions and countries around the globe pass laws to establish the vital principles of the convention which human rights campaigners call a “watershed”. However, many migrant workers servicing in the households of the rich are still suffering from violence, abuse and exploitation.
