However people feel about immigration, judges and lawmakers nationwide have long acknowledged that the employment of unauthorized workers is a reality of the American economy. Some 8 million immigrants work with false or no papers nationwide. They're more likely to be hurt or killed on the job than other workers. Nearly all 50 states, including Florida, have given these workers the right to receive workers' comp. But in 2003, Florida's lawmakers [made] it a crime to file a workers' comp claim using false identification. Since then, insurers have avoided paying for injured immigrant workers' lost wages and medical care by repeatedly turning them in to the state. In a challenging twist of logic, immigrants can be charged with workers' comp fraud even if they've never been injured or filed a claim, because legislators also made it illegal to use a fake ID to get a job. In many cases, the state's insurance fraud unit has conducted unusual sweeps of worksites, arresting a dozen employees. To assess the impact of Florida's law on undocumented workers, ProPublica and NPR analyzed 14 years of state insurance fraud data. We found nearly 800 cases statewide in which employees were arrested under the law. Insurers have used the law to deny workers benefits after a litany of serious workplace injuries. Flagged by insurers or their private detectives, state fraud investigators have arrested injured workers at doctor's appointments and at depositions in their workers' comp cases. Some were taken into custody with their arms still in slings.
