A federal lawsuit claims a supervisor at Lehigh Valley Health Network discriminated against workers over the age of 40.

Patti Kopko, a former case manager with LVHN, is suing the health network and her former boss.

Kopko says her former supervisor kept a list of employees over the age of 40 she wanted to terminate.

Kopko also claims she was retaliated against after complaining about violations of federal regulations at Lehigh Valley Hospital's campus in Salisbury Township.

At this point, LVHN officials are not commenting on the lawsuit.
