Gov. Jay Inslee has announced that, effective June 8, all business employees must wear a cloth face mask, except when working alone in an office, vehicle, or at a job site, or when the job has no in-person interaction.

Under the state’s “Safe Start” plan, employers must provide cloth face masks to employees, unless their exposure dictates a higher level of protection under the Department of Labor and Industries’ safety and health guidance. Employees can choose to wear their own facial coverings at work, provided it meets the minimum requirements.

Employers must also post signage at their place of business strongly encouraging customers to wear cloth face masks to help protect employees from exposure to COVID-19 in the workplace.

“Wearing a mask is strongly encouraged in most circumstances to protect the health of our communities,” Inslee said in a statement. “As we start to increases in travel, recreation, and economic activity, it is critical that we remain diligent in order to avoid a sharp increase in exposure. We will continue to closely monitor disease data to determine whether additional steps are needed to protect public health.”
