A group of Mexican migrants who spent years harvesting sugar cane on a Louisiana farm say they were forced to work long hours without overtime and paid illegally low wages. The workers are now suing Bayou Sugar Growers, a St. Martinville company that also has farms in Iberville and Pointe Coupee parishes. The plaintiffs are all from Mexico, recruited to the U.S. by Bayou Sugar through a Department of Labor work visa program that allows employers to hire foreign workers for seasonal agricultural jobs when there aren’t enough qualified American laborers.
