Washington WARN Act and Layoff Notice Requirements
Washington has its own layoff-notice law in addition to federal WARN. Here's who's covered, how much notice is required, the penalties, where to find official notices, and what employees should do.
Washington has its own layoff-notice law in addition to federal WARN. The state rule may cover smaller employers, smaller layoffs, longer notice, additional recipients, or different penalties. Whether it applies depends on the employer, worksite, number of affected employees, event type, and timing.
For Washington: Employers with 50 or more employees (as defined in Ch. 49.45 RCW). The covered event is a business closing or mass layoff affecting 50 or more workers at a single site. Covered events generally require 60 days' written notice before a covered mass layoff or business closing.
At a glance
Federal WARN vs Washington
The federal WARN Act is the nationwide baseline: it generally requires 60 days' written notice for a covered plant closing or mass layoff at employers with 100+ employees, with remedies of back pay and benefits enforced through the courts. Washington's state law can be broader — for example, Washington mass-layoff notice law (“Securing Timely Notification and Benefits for Laid-Off Employees Act”) (Chapter 49.45 RCW). The details below reflect the state rule.
Recent change: Washington's state WARN requirements took effect July 27, 2025 (SB 5525). An updated mass-layoff notice measure was signed in 2026 — confirm the current effective date and any changes that apply to layoffs occurring on or after that date with ESD before relying on specifics.

Penalties & employee remedies
An employer that orders a covered closing or mass layoff without required notice is liable to each affected employee for back pay and benefits, and is subject to a civil penalty of up to $500 per day payable to ESD (avoidable by paying employees within three weeks).
Back pay
Back pay for each day of violation, up to 60 days, at the employee's final rate of pay or their last three-year average rate, whichever is higher.
Benefits
The value of benefits the employee would have received, including medical expenses incurred because of the loss of the benefit plan.
Civil penalty
Up to $500 for each day of violation, payable to ESD — not owed if the employer pays affected employees the amounts due within three weeks of ordering the action.
How to raise it
Contact ESD about a suspected violation; ESD administers Washington's WARN requirements.
Major exceptions & special cases
- Faltering company — where notice would have precluded obtaining needed capital or business
- Unforeseeable business circumstances — sudden, dramatic, and unexpected action or condition outside the employer's control
- Natural disaster
Remote workers
Coverage follows the single site of employment; remote-worker treatment can be fact-specific — verify with ESD.
Temporary layoffs
Whether a temporary layoff or furlough triggers notice can depend on its expected length and the specific rule — verify with the agency for your situation.

Washington scenarios
A 60-person layoff after the 2025 law
Facts: A Washington employer lays off 60 workers at one site in September 2025.
Because Washington's state WARN requirements took effect July 27, 2025, a 50+ worker mass layoff at a single site can require 60 days' notice to ESD, affected employees, and the local elected official — with back pay and a potential $500/day penalty if notice wasn't given. Confirm the current rule for the layoff date.
Timing around a 2026 change
Facts: Your layoff date is in 2026 and you're unsure which version of the law applies.
An updated Washington mass-layoff notice measure was signed in 2026. The rule that applies can depend on whether your layoff occurred before or after the update's effective date, so verify the current effective date and requirements with ESD rather than assuming.
