The Whistleblower Law prohibits discharge or discrimination by a "public body" against an employee who makes a good faith report to the employer or appropriate authority concerning an instance of wrongdoing or waste. Claims must be filed within 180 days of the violation of the law. Employers may defend the whistleblower claim by proving that the employment action was for a separate and legitimate reason, and not merely pretextual. The aggrieved employee must show some nexus between the complaint and the violation of the law. Golaschevsky v. Commonwealth Dept of Environmental Protection.
