American farmworkers have often experienced egregious abuses, but nothing is more pervasive, nor harder to ferret out, than the wage theft that results from a practice called farm-labor contracting. Found in the fields of every handpicked crop in the country, farm-labor contractors not only provide growers with crews, but also handle wages and manage everything from verifying immigration status to providing workers' compensation. The problem is, the contractors systematically underpay the workers. “Farm labor contractors,” says writer Tracie McMillan, “give American produce growers what companies like China's Foxconn offer to Apple: a way to outsource a costly and complicated part of the business, often saving money in the process and creating a firewall between the brand and the working conditions under which its products are made.” And yet McMillan — a fellow with both the Knight-Wallace program at University of Michigan, and the Schuster Institute for Investigative Journalism at Brandeis University — found that enforcement is rare: In 2008, inspectors visited only 1,499 of the more than 2 million farms nationwide; in 2011, California inspectors found just seven minimum wage violations on the state's 86,000 farms. Fines are minimal: “It's cheaper to violate the law than to follow the law,” says one farmworker advocate. And wage theft is tedious to prove, requiring inspectors to interview workers, analyze time cards, and collect payroll records. That's why workers and their advocates in California are counting on a lawsuit brought earlier this year on behalf of two farmworkers against the contractors who hired them—as well as the growers who outsourced the work. The suit alleges that the contractors routinely undercounted the hours worked, failed to pay minimum wage or overtime, failed to provide safe or sanitary working conditions, and housed the workers in unsafe and unsanitary living quarters. The “collective action” suit—open to anyone who can prove he or she experienced the same treatment—may cover thousands of workers and deliver awards substantial enough to deter other employers from the same practices.
