A jury at Multnomah County Circuit Court has found Taco Bell guilty of violating Oregon's wage-and-hour laws. The Mexican fastfood subsidiary of Tricon Global Restaurants Inc has been ordered to pay back wages owed to 1,300 former workers in the state. The workers had filed the class-action lawsuit with allegations that their time cards had been tampered with so as to make it look as if managers had met productivity deadlines, and would therefore be eligible for personal bonuses.
