The Hidden Bilingualism of America’s Truckers, Farmers and Factory Workers

A bilingual crew leader is translating during a hectic harvest week in Ventura County’s strawberry fields. She does more than just this. She controls the crew’s speed, keeps an eye on the weather, tracks the boxes, and assesses the pick’s quality. However, the foreman’s morning instructions are constantly translated from English into Spanish, which is then filtered back to the two or three workers in her crew who speak Mixteco, an Oaxacan language for which there is no official interpreter at this operation and no county agency has enough staff. She works three jobs. She gets paid for one.

The pesticide safety label on the drum next to the irrigation equipment is a piece of federal compliance documentation that her staff members are unable to understand or effectively verify. Prior to the December 2022 law change, this label was typically only available in English. The margin for error is a workplace injury if she forgets a single instruction in the chain between the field supervisor and the Mixteco-speaking picker who inquires about the contents of the drum. In the Central Valley of California, this occurs thousands of times every day, but it is not officially tracked.

There is no metaphor to the “hidden bilingualism” of America’s blue-collar workers. It describes a real and quantifiable phenomenon where employees who speak two or more languages—Spanish and English, Mixteco and Spanish, Vietnamese and English in Southern food processing facilities—offer informal interpretation services as part of their regular workday without the title, compensation, and liability protection that come with being a professional interpreter.

The magnitude is noteworthy: over 76% of the 2.4 million farmworkers in the United States are immigrants, with the vast majority coming from Mexico and Central America. As of 2024, 31% of construction workers are Hispanic. In the Midwest and South, manufacturing facilities, meatpacking plants, and distribution centers operate with workforces where English is neither the primary nor the majority language on the floor, and where management’s official communications, such as safety briefings, machine operation updates, and shift change notices, are only available in English.

The manufacturing floor dynamic is the most undetectable form of the issue since it takes place inside structures where no one can see it from the outside and where the employees involved have little motivation to record it. A bilingual employee translating for the shift supervisor on an assembly line at a poultry processing facility in Alabama or an automobile supplier plant in central Tennessee is doing precisely what a professional interpreter would be hired to do at a hospital, a courtroom, or a business negotiation.

The distinction is that the interpreter at the hospital has a job title, a pay grade, and a professional code that specifies what they are and are not accountable for in cases of miscommunication. The multilingual employee on the factory floor is in charge of both their own station and the interpretation. If the safety instruction they translated turns out to be inadequate, there is no official accountability system in place, and the workers are solely liable.

Trucking gives this image a unique texture all its own. At major shipping hubs in Dallas, Los Angeles, Memphis, and Chicago, long-haul drivers and warehouse employees work in environments where loading dock procedures, route instructions, and Department of Transportation compliance requirements are all in English, even though a sizable portion of the workforce communicating at those docks does not speak English as their first language.

There are numerous bilingual drivers that translate between dispatchers and warehouse teams, between safety compliance officials and crews that are unable to respond to the officer’s inquiries without assistance, and between the job’s formal documents and the people performing it.

A route direction that loses a crucial detail between the English-only dispatcher and the non-English-speaking loader results in the kind of miscommunication that costs time, damages freight, and sometimes involves a regulatory problem. This is especially evident in the dispatch chain. As part of the job description that no one drafted for them, the multilingual employee in the center takes on that risk.

It’s difficult to ignore the fact that the employees carrying out this role are among the most economically vulnerable members of the American workforce; they are frequently immigrants, frequently lack documentation or have unclear immigration status, and frequently hesitant to make demands that might draw attention to themselves.

The failure to legally reward multilingual blue-collar workers for their interpretation job, according to labor advocates and sociologists who research this topic, is more than just a mistake. Because the workers most impacted have the least institutional capacity to alter it, this structural arrangement has continued to favor employers directly and repeatedly. In 2024, the number of bilingual job advertisements increased by 40%, mostly in professional fields where the ability is valued and apparent. The same expertise is intentionally unseen in the field, on the production floor, and at the loading dock.
