The Federal Worker Protection Act seeks to limit the use of nondisclosure agreements (NDAs) by federal agencies that could restrict whistleblowing by employees and contractors. Congress finds that such NDAs, even if nominally compliant, can have a substantial chilling effect on protected disclosures of waste, fraud, abuse, and violations of law. The bill aims to ensure that statutory whistleblower rights are not diminished by executive instruments. To achieve this, the bill mandates that all covered NDAs include a plain-language rider conspicuously stating an employee's protected disclosure rights to various oversight bodies, including Congress and Inspectors General. Furthermore, all NDA templates, including those from the Office of Personnel Management, must undergo pre-clearance by the Office of Special Counsel (OSC). The OSC will certify templates only if they do not restrict or discourage protected disclosures, or return them with objections. Agencies imposing non-compliant NDAs face civil penalties of not less than $5,000 per violation and must cover reasonable attorney's fees. The bill also creates a private right of action , allowing employees to sue agencies and officials for threatened or actual retaliatory NDA enforcement, seeking relief such as injunctive relief, compensatory damages, and attorney's fees. This action does not require exhaustion of administrative remedies. A core provision establishes the statutory supremacy of whistleblower protection laws, rendering any NDA provision that purports to restrict a protected disclosure void and unenforceable. Additionally, agency Inspectors General (IGs) must independently review and certify proposed NDAs for compliance with whistleblower statutes and this Act. If an IG issues a negative certification, the agency cannot impose the NDA until deficiencies are remedied. To protect IG independence, the President is restricted from removing or diminishing an IG's duties for two years following a negative certification, unless specific conditions are met and the removal is unrelated to their oversight activities. IGs are also required to submit annual reports to Congress on NDA practices, and the Government Accountability Office will conduct periodic audits. Existing NDAs must comply within 180 days of enactment, with their provisions construed under the new protections during the transition period.
