A federal judge has approved an $11.5 million class-action settlement involving more than 600 Mexican engineers and technical workers. Those workers say they were recruited for professional jobs in Georgia, only to be put on factory lines instead. The defendants include Kia Georgia, Hyundai Mobis, staffing firm Allswell, recruiting agency SPJ Connect, and others connected to the hiring arrangement. They all deny wrongdoing, but the settlement brings a long-running case over allegedly misused TN visas to a close.
