Oregon Revised Statutes Public Officers and Employees § 243.706

(1) A public employer may enter into a written agreement with the exclusive representative of an appropriate bargaining unit setting forth a grievance procedure culminating in binding arbitration or any other dispute resolution process agreed to by the parties. As a condition of enforceability, any arbitration award that orders the reinstatement of a public employee or otherwise relieves the public employee of responsibility for misconduct shall comply with public policy requirements as clearly defined in statutes or judicial decisions including but not limited to policies respecting sexual harassment or sexual misconduct, unjustified and egregious use of physical or deadly force and serious criminal misconduct, related to work. In addition, with respect to claims that a grievant should be reinstated or otherwise relieved of responsibility for misconduct based upon the public employer's alleged previous differential treatment of employees for the same or similar conduct, the arbitration award must conform to the following principles:

(2) In addition to subsection (1) of this section, a public employer may enter into a written agreement with the exclusive representative of its employees providing that a labor dispute over conditions and terms of a contract may be resolved through binding arbitration.

(3) In an arbitration proceeding under this section, the arbitrators, or a majority of the arbitrators, may:

(4) The arbitrators shall promptly provide a copy of a subpoena issued under this section to each party to the arbitration proceeding.

(5) The arbitrators issuing a subpoena under this section may rule on objections to the issuance of the subpoena.

(6) If a person fails to comply with a subpoena issued under this section or if a witness refuses to testify on a matter on which the witness may be lawfully questioned, the party who requested the subpoena or seeks the testimony may apply to the arbitrators for an order authorizing the party to apply to the circuit court of any county to enforce the subpoena or compel the testimony. On the application of the attorney of record for the party or on the application of the arbitrators, or a majority of the arbitrators, the court may require the person or witness to show cause why the person or witness should not be punished for contempt of court to the same extent and purpose as if the proceedings were pending before the court.

(7) Witnesses appearing pursuant to subpoena, other than parties or officers or employees of the public employer, shall receive fees and mileage as prescribed by law for witnesses in ORS 44.415 (2).
