Many domestic servants in Saudi Arabia are treated adequately,[12] but there have been numerous cases of abuse. Foreign workers have been raped, exploited, under- or unpaid, physically abused,[2] overworked and locked in their places of employment. The international organisation Human Rights Watch (HRW) describes these conditions as "near-slavery" and attributes them to "deeply rooted gender, religious, and racial discrimination".[12] In many cases the workers are unwilling to report their employers for fear of losing their jobs or further abuse.[12] Other forms of general discrimination, such as a lack of freedom of religion for non-Sunni Muslims, are also applicable.[12]
