On December 19, 2008, the federal Immigration and Customs Enforcement agency announced that IFCO Systems North American, a Texas-based manufacturer, agreed to pay $20.7 million to resolve a criminal investigation relating to the hiring of over 1,200 undocumented workers. The amount included $2.6 million for FLSA overtime wage violations to workers who were paid a piece rate to manufacture wood pallets. The company also agreed to upgrade its Form I-9 procedures throughout more than 150 facilities across the country. The settlement did not address criminal charges against company managers and employees, nine of whom have pleaded guilty to criminal violations.
