A Collin County residential builder received a hefty bill for unpaid overtime wages following a U.S. Department of Labor investigation. Investigators with the Wage and Hour Division found Northland Development of Texas Inc. paid their employees straight away instead of time and half their pay rate when they worked more than 40 hours in a workweek. In addition, they deducted more than the time taken for lunch, and 47 workers recovered over $163,500 in back wages.
