This Decision involves a complaint filed by Carlos M. Castillo (Castillo or “the complainant”) under the Department of Energy (DOE) Contractor Employee Protection Program, 10 C.F.R. Part 708. Castillo is the former employee of a DOE contractor, Kiewit Construction Company (Kiewit), and alleges in his complaint that during that employment certain reprisals were taken against him by Kiewit as a result of his raising a concern related to safety. These alleged reprisals include the complainant’s wrongful termination from employment and, after he had been rehired, being improperly selected for a company layoff. After a preliminary investigation of this matter by the DOE Office of Inspector General, Castillo and Kiewit exercised their option for an expedited hearing under 10 C.F.R. § 708.9. On the basis of the hearing that was conducted and the record before me, I have concluded that Castillo is not entitled to relief under 10 C.F.R. Part 708.
