This bill amends existing Washington paid family and medical leave law by changing definitions and related procedures in RCW 50A.05.010 and related provisions. It explicitly expands the definition of "employer" to include representatives for employers of dockworkers who normally work for several employers interchangeably under a collectively bargained agreement, and states those employer representatives are not required to report dockworkers who are not covered by the collective bargaining agreement except for the representatives' own employees. The bill does not create a new crime or change criminal penalties in the provided text; it is primarily a definitional and procedural amendment to existing law. The bill clarifies and adds definitions and rules used across the title: it defines premiums as the payments required by RCW 50A.10.030 to be paid to the Employment Security Department for deposit in the family and medical leave insurance account; it defines remuneration to include assigned previously accrued compensation and settlements from negotiated contract terminations (and to exclude tips, certain supplemental employer payments, and short military duty payments); it sets the qualifying period used to determine average weekly wage; it specifies how to calculate and round an employee’s average weekly wage; and it defines terms such as casual labor, family leave, family member, and typical workweek hours. It also references the commissioner’s role in setting maximum wages subject to premium assessment. The bill also specifies substantive eligibility and treatment rules for leave: it sets detailed criteria for what qualifies as a "serious health condition," requires the first or only in-person treatment visit to occur within seven days of the first day of incapacity (with extenuating circumstances defined), clarifies when pregnancy-related and chronic-condition incapacities qualify for leave without treatment, and states that substance abuse can qualify as a serious health condition only when the absence is for treatment rather than use. Employers may discipline for substance abuse under an established nondiscriminatory policy even if the employee took leave for treatment, but may not discipline because the employee exercised the right to take medical leave for treatment. The provided facts are limited to definition changes and certain eligibility rules; the text is incomplete in places (the definition of "period of incapacity" is cut off and full mechanics for premium collection for dockworkers and other implementation details are not included), so additional provisions or procedures in the full bill are not available from these extracts.

If enacted, the bill makes employer representatives for dockworkers—those who manage crews that work for several employers under a collective bargaining agreement—responsible in law for paid family leave premium collection and reporting for the dockworkers covered by those agreements, while not forcing those representatives to report dockworkers who are not covered except for their own employees. That will likely shift administrative responsibility and potential premium cost liability onto those representative entities, require payroll and reporting changes by employers (including treating previously accrued compensation and negotiated contract termination payments as wages for premium and benefit calculations), and give the Employment Security Department a clarified set of payments to collect and deposit into the family and medical leave insurance account; tips and certain employer supplemental payments and short military duty pay remain excluded from remuneration. Employers should expect increased payroll reporting and possible higher premium outlays where assigned past compensation or settlements now count as remuneration, employees may see clearer rules for qualifying periods and how their weekly wage is calculated (affecting benefit amounts), and employers retain limited ability to discipline for substance abuse under nondiscriminatory policies while still being prohibited from penalizing employees for taking leave for treatment. Key implementation details that would affect actual costs and enforcement—such as premium rates, collection procedures, and administrative timelines—are not included in the extracted text and remain uncertain.
