A nursing home staffing company was ordered to pay 150 workers upwards of $730,000 in unpaid overtime wages and interest, a federal judge ruled last week.

New Jersey-based Broadway Healthcare Management LLC was found to have withheld overtime pay from at least 150 direct care staff at 10 nursing homes in the state. Broadway failed to include overtime pay, shift differentials and bonuses in the employees’ paychecks, the Courier-Post reported.

This is the second time an investigation has found the agency withholding overtime pay from employees — the company was ordered in 2008 to pay back wages as the result of an investigation by the U.S. Dept. of Labor’s Wage and Hour Division.

The recent ruling found the company committed the same violations it was accused of in 2008; as a result it was found in contempt and ordered to pay $636,410 in back wages. Broadway must also pay $97,388 in legal and investigative costs.
