ORS 663.130: Union unfair labor practices.

It is an unfair labor practice for a labor organization or its agents: (1) To cause or attempt to cause an employer to discriminate against an employee in violation of ORS 663.125 or to discriminate against an employee with respect to whom membership in such organization has been denied or terminated on some ground other than the failure of the employee to tender the periodic dues and the initiation fees uniformly required as a condition of acquiring or retaining membership; (2) To refuse to bargain collectively with an employer, if it is the elected and certified representative of the employees; (3) To cause or attempt to cause an employer to pay or deliver, or agree to pay or deliver, any money or other thing of value, in the nature of an exaction, for services which are not performed or not to be performed; or (4) To restrain or coerce: (a) An employer in the selection of representatives for the purposes of collective bargaining or the adjustment of grievances; or (b) Employees in the exercise of the rights guaranteed in ORS 663.110. However, this paragraph does not impair the right of a labor organization to prescribe its own rules with respect to the acquisition or retention of membership therein. [1971 c.729 §9]
