Washington Revised Code Title 49. Labor Regulations § 49.48.085. Wage complaints--Employee termination of administrative action

(1) An employee who has filed a wage complaint with the department may elect to terminate the department's administrative action, thereby preserving any private right of action, by providing written notice to the department within ten business days after the employee's receipt of the department's citation and notice of assessment.

(2) If the employee elects to terminate the department's administrative action:  (a) The department shall immediately discontinue its action against the employer;  (b) the department shall vacate a citation and notice of assessment already issued by the department to the employer;  and (c) the citation and notice of assessment, and any related findings of fact or conclusions of law by the department, and any payment or offer of payment by the employer of the wages, including interest, assessed by the department in the citation and notice of assessment, shall not be admissible in any court action or other judicial or administrative proceeding.

(3) Nothing in this section shall be construed to limit or affect:  (a) The right of any employee to pursue any judicial, administrative, or other action available with respect to an employer;  (b) the right of the department to pursue any judicial, administrative, or other action available with respect to an employee that is identified as a result of a wage complaint;  or (c) the right of the department to pursue any judicial, administrative, or other action available with respect to an employer in the absence of a wage complaint.  For purposes of this subsection, “employee” means an employee other than an employee who has filed a wage complaint with the department and who thereafter has elected to terminate the department's administrative action as provided in subsection (1) of this section.
