Petitioner Portland Federation of Teachers and Classified Employees (Union) is the exclusive bargaining agent for employees of Portland School District 1J (District).1 It seeks review of an Employment Relations Board (ERB) order determining that the “fair share” provision in the parties’ collective bargaining agreement is invalid under ORS 243.650(10) and is not otherwise valid as a union security provision. We affirm.

Union and District negotiated a collective bargaining agreement effective from August 23, 1984, through June 30, 1987, which included this provision:

“Article 8

“PAYROLL DEDUCTIONS

* * * *

“B. Fair Share

‡ ifc jfc

“4. “If ‘fair share’ is approved by the employees, the District shall, upon request of the Federation, automatically deduct from payroll checks of the employees in the bargaining unit who are non-members of the Federation as a fair share payment in-lieu-of-dues. Such deductions by the District shall be remitted to the Federation along with any deducted payroll dues. Such amount shall not exceed the usual and customary monthly dues of the Federation.”

A majority of the employees in the bargaining unit voting on the issue approved the provision. In November, 1984, District and Union amended the provision to exempt from payroll deductions employees working fewer than 15 hours per week. Seven employees and the Oregon School Employees Association (OSEA) then filed an unfair labor practice complaint with ERB, alleging, inter alia, that Union had violated ORS 243.672(2), because the provision is not a valid “fair share” provision under ORS 243.650(10). ERB agreed and ordered Union to cease and desist from enforcing the provision and to *224reimburse the complainants for all amounts collected within the 180 days before the filing of the complaint.

Petitioner now concedes that, because the agreement exempts employees working fewer than 15 hours per week, it does not fall within the definition of “fair share” under ORS 243.650(10) and (16).2 In that, it is correct: The statute requires that, in order to qualify as a fair share agreement, “all persons” who are not union members must be required to make payments in lieu of dues. Nevertheless, it argues that ERB erroneously interpreted a provision of law by not holding that the provision is a union security arrangement that is valid, because it is no more restrictive than the “fair share” agreement allowed by statute.

Petitioner relies on Stines v. OSEA, 287 Or 643, 601 P2d 799 (1979). In Stines, the complainant was a former union member who wished to withdraw from the union but was required to continue paying dues or their equivalent under this contract provision:

“Section 1. All members of the bargaining unit who are members of the Association as of the effective date of the agreement or who subsequently voluntarily become members of the association shall continue to pay dues, or the equivalent, to the Association during the term of this agreement.”

The Supreme Court held that the provision did not qualify as “fair share,” because it did not require contributions by all nonunion employees. It was, instead, a recognized form of *225union security agreement, a “maintenance of membership” provision, the enforcement of which would constitute an unfair labor practice unless it was the equivalent of a “fair share” provision or was a less severe form of union security arrangement than a “fair share” provision under the rule of NLRB v. General Motors Corp., 373 US 734, 83 S Ct 1453, 10 L Ed 2d 670 (1963). The court pointed out that the maintenance of membership clause only applies to those who had willingly and voluntarily joined the union, whereas a “fair share” provision includes all employees who are not members of the union, whether they have ever joined or not. Therefore, it concluded that the questioned provision was less restrictive than “fair share” and was permissible. The case does not help petitioner.

The provision here, like the one in Stevens v. OPEU, 82 Or App 264, 728 P2d 70 (1986), rev den 303 Or 172 (1987), is clearly an attempt to have a “fair share” provision without complying with the statutory requirements. It is labelled “Fair Share” and, in its original form, it met the statutory requirements; however, as amended, it does not. Its intended purpose is unquestionably the collection of “fair share” payments from some, but not all, nonunion members in the bargaining unit, and it does not qualify as any other kind of recognized union security arrangement.3

Affirmed.
