Modifying the securing timely notification and benefits for laid-off employees act. (REVISED FOR ENGROSSED: Concerning the laid-off employees act.)

Indian tribes are now excluded from the definition of 'employer' under the WARN Act, meaning they are not required to provide advance notice for mass layoffs or business closings.

A new exemption was added to the public records law to shield employee names and addresses provided to the Employment Security Department for layoff notices from public inspection and copying.

A specific definition for 'part-time employee' was added to clarify which workers are excluded from mass layoff thresholds.

The bill text was updated to reflect changes in the referenced statutes, including adding RCW 49.45.020 to the list of amended sections and renumbering the emergency clause from Section 3 to Section 4.
