Oregon Revised Statutes Labor and Employment; Unlawful Discrimination § 663.180

(1) A person may file with the Employment Relations Board a charge that another person has engaged in or is engaging in an unfair labor practice. The person filing the charge shall pay a fee of $300 to the board. The board shall deposit fees received under this section to the credit of the Employment Relations Board Administrative Account.

(2) If it is charged that a person has engaged in or is engaging in an unfair labor practice, the board shall cause an investigation to be made. If, on the basis of this investigation, it appears to the board that an issue of fact or law exists as to a violation of ORS 663.120 to 663.165, the board shall issue a complaint. The complaint shall contain a notice of hearing before the board, at a place fixed in the notice, not less than five days after the serving of the complaint.

(3) Notwithstanding subsection (2) of this section, the board may not issue a complaint based upon an unfair labor practice occurring more than six months before the filing of the charge with the board, and the service of a copy of the charge upon the person against whom the charge is made, unless the person aggrieved by the unfair labor practice was prevented from filing the charge by reason of service in the Armed Forces of the United States, in which event the six-month period shall be computed from the day of discharge.
