The bill amends RCW 49.46.210 to expand the reasons for which employees can use paid sick leave. Specifically, it allows employees to use paid sick leave to prepare for or participate in judicial or administrative immigration proceedings involving themselves or their family members. This addition is marked by the insertion of new legal language that specifies this purpose. Additionally, the bill clarifies the verification process for absences related to immigration proceedings, stating that employees can provide a written statement or documentation from an advocate, attorney, or clergy member to confirm their involvement in such proceedings.

Furthermore, the bill maintains existing provisions regarding the accrual and use of paid sick leave, including the requirement for employers to provide at least one hour of paid sick leave for every forty hours worked. It also reiterates that employees are entitled to use accrued paid sick leave for various health-related reasons, care for family members, and in situations where their workplace or their child's school is closed for health-related reasons. The bill emphasizes that employers cannot retaliate against employees for exercising their rights under this law, including the use of paid sick leave for the newly added immigration-related purposes.
