MIAMI (AP)  Darden Restaurants violated federal labor laws by underpaying thousands of servers across the country at Olive Garden, LongHorn Steakhouse, Red Lobster and other eateries, according to a lawsuit filed Thursday on behalf of the workers.

The lawsuit filed in Miami federal court seeks to collectively represent current and past employees who worked for Darden from August 2009 to the present. It seeks potentially tens of millions of dollars in back pay and other compensation, plus interest and attorney fees, said lead lawyer David Lichter.
