Tyson Foods Inc, one of the world's largest meat processors, on Wednesday won the reversal of nearly $24 million of damage awards in two class action lawsuits claiming it cheated thousands of hourly workers in two Nebraska plants out of wages. The 8th U.S. Circuit Court of Appeals in St. Louis overturned an $18.77 million award to workers at a Madison, Nebraska pork processing plant after a non-jury trial.
