The bill establishes a new section in chapter 49.44 RCW that prohibits employers from searching the personal vehicles of employees parked on the employer's premises, with specific exceptions. Employers and their agents are barred from conducting such searches unless certain conditions are met, including lawful searches by law enforcement, situations where the employee's vehicle is used for work-related activities, or if there is probable cause to believe the employee possesses unlawful items. Additionally, employees cannot be required to waive these protections as a condition of employment.

The legislation also protects employees from adverse actions taken by employers for exercising their rights under this section. Adverse actions include wage denial, termination, demotion, or any changes to work hours or schedules. The bill emphasizes that employees have the right to consent to searches under specific circumstances, and they can select a witness to be present during such searches. Overall, the bill aims to safeguard employee privacy regarding their personal vehicles while outlining clear guidelines for permissible searches.
