HB 1155 Eliminates Most Noncompete Agreements — Legislation
Date: March 30, 2026
Summary:
Washington enacted HB 1155, a sweeping reform that voids most employment-related noncompetition agreements for employees and independent contractors. The law significantly broadens the definition of prohibited restrictive covenants and applies retroactively to agreements challenged after the effective date. Employers must also provide notice to covered workers with existing agreements that those restrictions are unenforceable.
Implications:
This is one of the most aggressive noncompete bans in the country. Washington employers should immediately review offer letters, separation agreements, contractor agreements, and restrictive covenant templates. Employees may gain greater mobility and leverage in changing jobs or launching competing ventures.
Washington Expands State WARN / STABLE Act Rules — Legislation
Date: March 2026 (signed during session)
Summary:
Washington also amended its state mini-WARN law, known as the STABLE Act. Changes include narrowing certain employer definitions and limiting disclosure of personal information tied to workforce reductions. The law remains focused on advance notice obligations during mass layoffs and plant closings.
Implications:
Employers planning restructurings, layoffs, or closures in Washington should reassess notice obligations under state law, which can differ from federal WARN requirements.
Unemployment Benefits Expanded for Voluntary Reduction-in-Force Participation — Legislation
Date: March 2026 (signed during session)
Summary:
Washington enacted HB 2264, allowing certain workers to receive unemployment benefits after voluntarily participating in an employer reduction in force. Previously, workers who accepted voluntary separation packages could face eligibility uncertainty.
Implications:
This may make voluntary severance programs more workable for employers while improving financial protections for affected employees.
Washington Proposes New Equal Pay & Job Posting Rules — Agency Rulemaking
Date: March 26, 2026
Summary:
The Washington Department of Labor & Industries continued rulemaking to implement recent amendments to the Equal Pay and Opportunities Act. Proposed rules address wage and salary disclosure in job postings, clarify who qualifies as an applicant, and implement restrictions on requiring a driver’s license unless job-related.
Implications:
Washington employers should carefully review recruiting and hiring practices, especially job postings, compensation transparency language, and screening criteria. Enforcement risk remains high in this area.
Washington Creates “Trigger” Collective Bargaining Framework for Private Employers — Legislation
Date: March 2026 legislative passage
Summary:
Washington approved a contingent state labor-relations framework that would activate if federal labor law no longer preempts state regulation or if the NLRB declines jurisdiction over certain employers. The law outlines union certification, bargaining, arbitration, and strike procedures under state oversight.
Implications:
Although contingent, this is a significant pro-labor structural move. Private employers in Washington should monitor federal labor developments because shifts in NLRB jurisdiction could trigger state regulation.
Personnel File Access Rules Continue to Expand — Agency Rulemaking
Date: March 2026
Summary:
Washington Labor & Industries advanced expedited rulemaking to align regulations with 2025 legislation expanding employee and former employee rights to access personnel records and pursue remedies for violations.
Implications:
Employers should maintain organized HR files and timely response procedures for personnel record requests. Delays or incomplete responses may create legal exposure.
