Washington Whistleblower Laws: Protections and How to Report

Frequently Asked Questions

Who can file a whistleblower complaint with the Washington State Auditor?

Any state employee may report improper governmental actions to the State Auditor under RCW 42.40. The report must be in writing and submitted within one year of the improper action. The law preserves the confidentiality of whistleblowers and individuals who provide information during investigations.

Can I file a qui tam lawsuit for Medicaid fraud in Washington?

Yes. The Washington Medicaid Fraud False Claims Act (RCW 74.66) allows private citizens to file qui tam lawsuits on behalf of the state. If successful, whistleblowers receive between 15% and 30% of the recovered funds, depending on the Attorney General's involvement and the whistleblower's contribution to the case.

How long do I have to file a whistleblower retaliation claim in Washington?

Deadlines vary by statute. WISHA workplace safety complaints must be filed within 90 days, and hazardous substances complaints share that 90-day window because RCW 49.70.110 applies the chapter 49.17 RCW discrimination provisions. Anti-discrimination complaints have a six-month deadline. Workers' compensation retaliation claims must be filed within 90 days. Most other statutory claims have a three-year deadline.

Does Washington protect private sector whistleblowers?

Yes, through a combination of common law and specific statutes. Washington's common law public policy exception protects employees who refuse illegal activities, exercise legal rights, report employer misconduct, or perform public duties. Additional statutes cover discrimination, workplace safety, wages, and healthcare.

What damages are available for whistleblower retaliation in Washington?

Remedies vary by statute. Common remedies include reinstatement, back pay with interest, restoration of benefits, and attorney's fees. Under the anti-discrimination statute, damages for humiliation and mental suffering up to $20,000 may be awarded. Under the Medicaid False Claims Act, employees may recover double back pay.

Updates

Corrected the hazardous substances retaliation filing deadline from 30 days to the 90 days RCW 49.17.160 actually allows, replaced a non-statutory 'abuse of authority' prong with the six categories of improper governmental action in RCW 42.40.020(6), raised the farm labor contractor fine to the $5,000 maximum in RCW 19.30.150, and narrowed two overstated coverage claims about state employees and hospital abuse reporters.

Governing law re-checked for recent changes
