This bill establishes a new chapter in Title 49 RCW that places agricultural workers involved in the cultivation, growing, harvesting, or production of cannabis under the jurisdiction of the Public Employment Relations Commission (PERC) for collective bargaining purposes. It defines key terms such as "employee," "employer," "bargaining representative," and "labor dispute," and outlines the rights of employees to organize and select their bargaining representatives without interference from employers. The bill mandates that employers must engage in collective bargaining and prohibits unfair labor practices by both employers and bargaining representatives.

Additionally, the bill details the procedures for certifying bargaining representatives, conducting elections, and the obligations of employers regarding dues deductions from employees' salaries. It also stipulates that collective bargaining agreements remain in effect after their termination until a new agreement is reached, and it allows for binding arbitration of disputes. The commission is empowered to prevent unfair labor practices and issue remedial orders, ensuring compliance with the new regulations. Overall, the legislation aims to enhance labor rights and protections for cannabis agricultural workers in Washington State.
