“They said, ‘You will work. You will work.’ ” She said that she left after her employers demanded that she wash the windows at 3 a.m.

The existence of the shelters reflects a hard reality here: With few legal protections against employers who choose not to pay servants, who push them too hard, or who abuse them, sometimes there is nothing left to do but run. The laws that do exist tend to err on the side of protecting employers, who often pay more than $2,000 upfront to hire the maids from the agencies that bring the women here.

The problems in Kuwait, including a lack of legal protection, are hardly unusual or even regional; this summer, New York became the first state to grant workplace rights to domestic employees in an effort to prevent sexual harassment and other abuses. But human rights groups say the potential for mistreatment is acute in several countries in the Middle East, especially those with large numbers of migrant workers who rely on a sponsorship system that makes employers responsible for the welfare of their workers.

That system is particularly entrenched in Kuwait, where oil riches allow many families to have several servants, human rights advocates say. And conditions for some workers here are bad enough that the United States Department of State in a 2010 report singled out Kuwait, along with 12 other countries, for failing to do enough to prevent human trafficking.

The report noted that migrants enter Kuwait voluntarily, but “upon arrival some are subjected to conditions of forced labor by their sponsors and labor agents, including through such practices as nonpayment of wages, threats, physical or sexual abuse, and restrictions on movement, such as the withholding of passports.”
