This bill amends RCW 1.16.050 to enumerate state legal holidays and to add the twelfth day of December as a day "recognized as the day of the 12s." It also adds a new legislative findings section that describes and recognizes the "12s" (Seattle Seahawks fans) and states the legislature's intent that the day of the 12s be a celebration of that community. The change modifies existing law and creates a separate new findings section. The amended holiday provisions reiterate rules for observing holidays that fall on weekends, allow state and political subdivision employees (with specified exclusions) one additional paid holiday per year selected in consultation with the employer under guidelines set by the appropriate personnel authority or local ordinance/resolution, and allow two unpaid religious or conscience leave days per year except where undue hardship or public safety needs prevent the leave. When a state legal holiday and a federal legal holiday fall on different dates, state employees recognize only the state date as a paid holiday; port districts and municipal law enforcement and public transit employees may recognize either the federal or state date, but not both. The text also states it does not add or delete paid holidays provided by collective bargaining or local law. The office of financial management is referenced for the meaning of "undue hardship." The document excerpt does not show where the new findings section will be codified, does not define the identity or authority of the "appropriate personnel authority" referenced for issuing guidelines, and does not include any additional operative language beyond the recognition in RCW 1.16.050 and the findings. It also references an amendment to "2024 c 76 s 3" without providing the prior or comparative text.

If enacted, December 12 would be added to the list of state legal holidays as the "day of the 12s," and the legislature formally recognizes it as a day to celebrate Seattle Seahawks fans. That change would likely mean state employees and many local government employees must treat that day under the same holiday rules that apply to other state legal holidays, which can increase paid time-off costs for the state and for political subdivisions unless a collective bargaining agreement or local ordinance provides otherwise, and it will affect scheduling and payroll practices for school districts, certain higher education employees, ports, and municipal law enforcement and transit staff subject to the holiday rules described in RCW 1.16.050. The bill also adds a findings section recognizing the 12s and references that appropriate personnel authorities and the Office of Financial Management will have roles in issuing guidelines or defining "undue hardship," but the text provided does not say exactly where that findings section will be codified or precisely which entity is the "appropriate personnel authority," so some implementation details and administrative responsibilities remain uncertain.
