The Tennessean reported yesterday on the miserable work life of a 17-year old migrant worker named Ivan Alvarez, who lost three fingers when a tobacco farmer’s makeshift shearing machine sliced them off. How did the farmer treat him? He gave him a check for $100 and fired him. No worker’s compensation, no disability insurance, and no compassion.

Young Alvarez was one of six migrant teenagers working at Marty Coley Farms in Macon County, Tennessee. He lived with 13 adult men in a vermin-infested three-bedroom house, and was paid less than minimum wage for six days a week of work. Why did Alvarez and the others put up with such mistreatment? As undocumented immigrants, they were trapped.

A recorded conversation between the farm’s owner and one of the employees after the amputation shows how employers use the threat of deportation to oppress their workers and drive labor standards to the bottom. When the worker said he was leaving to take a better-paying job at another farm, the farmer, Marty Coley (one of the largest tobacco growers in the county), threatened him with deportation.

“I’ll tell you what,” Coley said. “You all go there and I’m going to call immigration and clean the whole damn bunch out.”

It adds insult to injury to learn that, as The Tennessean reported, Marty Coley Farms has received more than half a million dollars in federal tobacco price support subsidies over the past ten years.

One often hears that employers hire undocumented migrants because no American wants to do the kind of work they’re hired to do. Clearly, no American wants to live in overcrowded and disgusting quarters, be paid a subminimum wage, and have his fingers cut off. The answer isn’t to let this kind of exploitation continue—it’s to improve pay and working conditions enough that Americans will do the work, and to give immigrants the right to reject a job that degrades rather than rewards their labor. As long as the undocumented workforce is subjected to the threat of deportation, Marty Coley Farms and other low-road employers will continue to abuse and exploit them, to the detriment of every American.
