Houston – The U.S. Department of Labor says many Houston grocery store workers are owed $406,000 in back pay. In a press release, the Department announced it recovered $460,000 in back wages and damages for 104 workers after it says Y.S. Lee Company Inc., operating as Guanajuato Supermarket on East Mount Houston Road, paid employees regular wages instead of the required time and a half for overtime, and failed to keep accurate pay records.
