Oregon Revised Statutes Labor and Employment; Unlawful Discrimination § 663.145

(1) Notwithstanding ORS 663.140, nothing in ORS 663.130 to 663.150 makes unlawful a refusal by any person to enter upon the premises of an employer (other than the person's own employer), if the employees of that employer are engaged in a strike ratified or approved by an elected and certified representative of the employees whom the employer is required to recognize.

(2) For the purposes of ORS 663.140 only, nothing in that section prohibits publicity, other than picketing, for the purpose of truthfully advising the public, including consumers and members of a labor organization, that a product is produced by an employer with whom the labor organization has a primary dispute and is distributed by another employer, as long as such publicity does not have an effect of inducing an individual employed by any person other than the primary employer in the course of employment to refuse to pick up, deliver or transport any goods, or not to perform any services, at the establishment of the employer engaged in such distribution.
