The 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," "collective bargaining," and "labor dispute," and outlines the rights of employees to organize and select their bargaining representatives. The bill prohibits employers from interfering with employees' rights to organize and mandates that the commission intervene in disputes regarding the selection of bargaining representatives. It also details the process for determining appropriate bargaining units and conducting elections for representation.

Additionally, the bill outlines the responsibilities of employers regarding the deduction of union dues, the continuation of collective bargaining agreements after their expiration, and the handling of unfair labor practices by both employers and bargaining representatives. It grants the commission authority to prevent unfair labor practices and issue remedial orders, while also allowing for the appointment of arbitrators to resolve disputes. The provisions specifically apply to employees engaged in cannabis-related work and clarify that the chapter does not extend rights to employees not directly involved in such activities.
