BOISE, Idaho (AP) — Employees at a call center for state health insurance exchanges are suing their employer in federal court, saying they were forced to work unpaid overtime.

The nine workers who brought the suit against Maximus Inc. say the case could potentially apply to thousands of workers, and they're asking a judge to award damages exceeding $5 million. Maximus has not yet filed a response. A phone call seeking comment yesterday was not immediately returned.

The workers say they were wrongly classified as exempt from overtime and required to work up to 60 hours a week in violation of federal law. The call centers were established to handle customer service for the exchanges established under the Affordable Care Act. The suit was filed in Idaho's U.S. District Court on Friday.
