The suit was filed in U.S. District Court on behalf of three current and former workers, and seeks class-action status to represent computer installers and maintenance workers for IBM throughout the United States. "They were forced to work overtime without being paid in a manner that is required by the state and federal laws," attorney James Finberg said. Lawyers said they are seeking millions of dollars in back pay, and are also considering punitive damages.
