What is a Maquiladora?

Maquiladoras are factories that are set up along the U.S. – Mexico border that take raw materials, often hazardous, from their country of origin, and have low-wage Mexican workers assemble them into finished goods, which are then shipped tariff-free back to their country of origin. Workers assemble electronics, medical equipment, automotive parts, communications equipment, and other goods. The vast majority of maquiladoras are owned by U.S. companies36 including General Motors, Zenith Electronics, Chrysler, Ford Motors, and General Electric37. A smaller number are owned by companies in Germany, Canada, Japan, Britain, Australia, and other countries38

The toxic waste from maquiladoras’ activities is often improperly disposed of in Mexico39, which has environmental laws that are generally as strict as those in the U.S., but a policy of allowing self reporting that allows pollution to go unregulated37. Polluted wastewater flows through the New River, and factory emissions flow through the air37. Their waste is a burden to the people that damages ecosystems and harms the surrounding communities, both in Mexico and the U.S., as it flows through Mexicali, through the permeable border wall, and north to the Salton Sea40.

A History, and Present, of Exploitation

Maquiladoras were formed In the 1960s, after President Kennedy ended the Bracero program41, which had allowed approximately 46 million Mexican men to work on short term labor contracts in the U.S. From 1942 to 196442. Most braceros worked as agricultural field hands in positions left by soldiers who left for World War II. They faced substandard housing, contract violations, physical mistreatment43, and wage theft42 . However, thanks to the work of Cesar Chavez, the Farmworkers’ Movement, and other activists, by the 1960s, the American people were no longer willing to put up with the exploitation and poor working conditions braceros experienced in the U.S. and the Bracero Program ended. Nonetheless, when the workers returned to Mexico they needed employment41, and the U.S. continued to demand labor at wages lower than those given to American workers41. To solve both problems, the U.S. and Mexican governments collaboratively developed the maquiladora program, which was advertised as a win-win for both countries and their people.

Working conditions in maquiladoras today are similar to those of nineteenth-century U.S. sweatshops. Jobs are hyper-specialized, so they require repetitive, microscopic assembly work under stressful conditions with very little autonomy44. Employees work long hours with few rest periods, and are also exposed to toxic chemicals, including solvents and carcinogens, in poorly ventilated factories37. Workers are provided with insufficient information on the toxicity of the materials and are often unaware of the perils involved in their jobs. Additionally, maquiladoras lack industrial hygiene and security measures, so workers are at risk due to inadequate lighting, excessive noise, and unsafe machinery37. These facilities have been involved in a number of violations of toxic waste transport laws, documented accidental discharges of dangerous wastes, and injuries from smoke inhalation due to accidental fires37. As a result, workers suffer from musculoskeletal disorders from un-ergonomic working conditions and acute health effects correlated with chemical exposures44. These conditions exist across many fields; textile and apparel workers, for instance, demonstrate pulmonary problems, eye problems, dermatitis, and hand injuries45. Electronic assembly workers report eye irritation, visual acuity loss, headaches, nervousness, and allergies45. Women in maquiladoras are more likely than workers in other sectors to deliver babies with low birth weights46. Some might point out that these employees are recruited from impoverished areas near the maquiladoras, and that, consequently, assigning causality related to the maquiladoras is difficult, The factories, by virtue of common sense alone, cannot be eliminated as causes—the dilemma does, however, indicate that there is exploitation occurring across many dimensions in the lives of maquiladora workers44, 45.

In addition to affecting the health of their workers, the maquiladoras have warped the sociological fabric of the areas they are in. They have brought massive population growth to the border cities, but little infrastructure to support this growth37. The population of Mexicali has doubled since the 1980s, when NAFTA popularized the maquiladora system, but little has been done to increase its infrastructural capacity37. In the 1990s, the lack of sewage infrastructure meant that raw sewage was dumped into the New River drainage daily21. The insufficient treatment capacity still leads to overflows that release raw sewage into the river multiple times a year47 .

The growth in population accompanied by a lack of reinvestment has caused a shortage of affordable housing. This, in turn, has led to a surge in the number of people living in colonias, subdivisions without water, sewage, electricity, paved roads, or other basic utilities37. The impact of the maquiladoras goes far beyond the hazards of the working conditions. They fuel the very deprivation that drives workers to their door.

Maquiladoras Disregard Covid-19 Closures

On March 31, 2020, as the Covid-19 pandemic took hold, President Andres Manuel Lopez Obrador ordered all non-essential businesses to close, but, under pressure from U.S. companies, the maquiladoras refused. Workers, afraid of getting ill at work and spreading the deadly disease to their families, peacefully protested outside their workplaces. On April 10th, the Baja California government and the federal Secretary of Health in Mexicali stepped in and closed 10 maquiladoras in Mexicali for failing to comply with the required safety closures48,49. However, U.S. manufacturers and the U.S. government continued to apply pressure to reopen them. On May 18th, the Mexican government announced that the auto manufacturing, aerospace, mining, industrial construction, and railway sectors were to be deemed essential services, and workers were forced to return50

Conditions for Women

Maquiladoras create special hardships for women and families. They take advantage of the social conditions that make it acceptable to pay women less than men. Managers see women’s work as unskilled–though many paradoxically believe that women have nimble fingers, dexterity, docility, and the capacity to do monotonous activities. Managers don’t seem to consider the fact that women hold such positions because those are the only jobs for which they are hired51. Counter to the arguments that women’s work is less valuable, however, is the fact that when maquiladoras first opened, over 2/3 of all hires were women. That figure reached 80-90% in some cities37.  In 1979, the maquiladora workforce was comprised of 77% women and 23% men, but employers soon exhausted the supply of women in the labor market, and had to start hiring men as well37. By 2003, the demographics had shifted so that only 54% of maquiladora employees were women while 46% were men51.

Today, managers continue to refer to jobs in maquiladoras as women’s work. They often prefer to hire married women with children, who they see as more responsible due to the economic need imposed by their families52.  Married women are more likely to leave the home to work in depressed economic markets than other workers so that they can increase the household income,. Since they are desperate for work, they will accept any wage that is offered. Womens’ wide employment at low wages in maquiladoras further drives down the price of their labor throughout the local market52

Despite the preference for hiring mothers, Human Rights Watch reports that women are forced to submit to pre-employment pregnancy tests (or show used sanitary napkins to prove they are not pregnant upon hire—a practice that is particularly common in Juarez53. Managers often refuse to pay wages during pregnancy, and threaten women with losing their positions if they take maternity leave. Such practices are inherently sexist, as pregnancy is a condition that can only happen to women53. The wide scale employment of women in the maquiladora system has caused an increase in male unemployment and forced men to leave their families to migrate into the U.S., leaving many towns with only women, children, and elderly men today. Often, families first move to the border region in search of work. The women find jobs in maquiladoras, but men, with few local employment prospects, must cross the border alone to help earn money for their families. Family members who remain near the border in Mexico might follow later, but in the meantime, they remain with their family incomplete, as survival requires them to combine wages, health care and other benefits from the maquiladora with remittances from those who have gone to the United States.54 Maquiladoras engage in dehumanizing practices against their employees, as they drive down local wages, break apart communities, and disrupt family life. The maquiladora system thereby causes widespread reverberations through family structures across Mexico and the U.S. border region.
