Oregon Revised Statutes Public Health and Safety § 441.192

(1) A hospital, as defined in ORS 441.179, may require a registered nurse who is receiving full employment benefits from the hospital to provide notice of any outside employment that may reasonably impede the ability of the nurse to fulfill the nurse's obligation to the hospital in providing nursing services to patients under the hospital's care.

(2) If a hospital determines that the outside employment causes a risk to patients receiving services in the hospital, the hospital may require the nurse to discontinue the outside employment.

(3) A hospital may not unreasonably restrict the outside employment of nurses and may restrict outside employment only if the hospital provides in writing to the nurse an explanation of the hospital's documentation that the outside employment creates a risk to patients in the hospital. A nurse who does not discontinue outside employment if required by the hospital may be disciplined or terminated from employment by the hospital.

(4) A nurse who does not provide notice as required by a hospital pursuant to this section may be disciplined or terminated from employment by the hospital if the failure to provide notice creates a risk to a patient in the hospital.
