The U.S. Department of Labor says a Decatur rehabilitation center has paid $67,000 in back wages after failing to properly compensate employees for overtime.

An investigation found that Lincoln Rehabilitation Center violated federal law by failing to pay employees for all hours worked and by improperly exempting some employees from overtime requirements.

The Labor Department says 138 employees received back wages. Lincoln Rehabilitation Center is a 140-bed nursing home managed by Skokie-based YAM Management, which also manages 19 other Illinois nursing home facilities.
