Miriam Delgado was one of 700 workers making printer cartridges in the border city of Juárez for the American-owned printer and software company Lexmark. She's the main reason foreign companies choose to set up factories, also known as maquiladoras, in places like northern Mexico.
Workers like her will work for cheap, as little as $7 a day. After five years working a nine-hour shift on an assembly line, Delgado began pressing for a raise. Then, last week, she was fired.
