Maquiladoras, or export-processing factories, along the U.S.-Mexico border account for over US billion in export earnings for Mexico and employ over 500,000 workers. At least half of the Mexicans employed in this sector, mainly in assembly plants, are women, and the income they earn supports them and their families at wages higher than they could earn in any other employment sector in northern Mexico. These women workers routinely suffer a form of discrimination unique to women: the maquiladoras require them to undergo pregnancy testing as a condition of employment and deny them work if they are pregnant; if a woman becomes pregnant soon after gaining employment at a maquiladora, in some instances she may be mistreated or forced to resign because of her pregnancy. Maquiladora operators target women for discriminatory treatment, in violation of international human rights and labor rights norms. And despite its international and domestic legal responsibility to ensure protection for these workers, the Mexican government has done little to acknowledge or remedy violations of women's rights to nondiscrimination and to privacy. In addition, the Mexican government's failure to remedy discrimination in the maquiladoras infringes on women's right to decide freely and responsibly on the number and spacing of their children.
