Opinion for the Court filed by Circuit Judge D.H. GINSBURG.
The National Labor Relations Board held that a union does not commit an unfair labor practice when it declines an employer’s demand for information about the union’s finances in the course of bargaining over the amount of thе agency fee that non-union employees will have to pay to the union. The Board held that the amount of an agency fee is not a mandatory subject of bargaining and does not become so by virtue of a union and an emplоyer’s agreement to negotiate over it, and that therefore, a union’s refusal to provide information relevant to that issue does not implicate the NLRA.
Social Servs. Union, Local 535,
I. Facts
The Social Services Union, Local 535, and the Employer, petitioner North Bay Development Disabilities Services, Inc., entered into a collective bargaining agreement (CBA) containing an agency shop clause that required each employee either to join the Union or to pay it an agency fee not in excess of that allowed by “the pertinent case law.” The CBA also required the parties to negotiate over “the amount of Agency fee to be paid” and provided that if agreement were not reached by a specified date (long since passed) “the issue shall be submitted to an arbitrator.”
In the ensuing negotiations, the Employer proposed that the agency fee be set at 20% of the periodic dues paid by Union members. The Employer also requested that, in the event that the Union did not agree to the 20% figure, it provide the Employer with “a detailed breakdown of all revenues and expenditures” of both the Local and the International for the current and the prior three years. The Employer maintained that this information was necessary in order for it and the Union jointly to determine what percentage of the members’ dues are spent on representation, and thus the maximum that nonmembers could be charged for the Union’s services.
When the Union refused to supply the information, the Employer invoked the arbitration сlause of the CBA. The Employer has since adhered to its demand for the information on the ground that it is necessary to the presentation of its case before the arbitrator. The Employer also filed an *478 unfair labor practice charge with the Board, alleging that the Union's refusal to provide the requested information constituted a refusal to bargain in good faith, in violation of § 8(b)(3), 29 U.S.C. § 158(b)(3). The Regional Director of the NLRB issued a complaint, an AU ruled that the Union had not violated § 8(b)(3), and the Board (insofar as is relevant here) "affirm[ed] the judge's rulings, findings, and conclusions and ... adopt[ed] the recommended Order." In so doing, the Board explained
that the amount of agency fees [sic] is a nonmandatory subject of bargаining and that it is not transformed into a mandatory subject by virtue of the parties' agreement to bargain concerning it. Inasmuch as the duty to provide information is coextensive with the statutory duty to bargain concerning mandatory subjects, [the Union] hаd no duty to provide information requested here.
The Employer petitions for review. It argues that the Board erred insofar as it held that the amount of an agency fee is not a mandatory subject of bargaining, and that even if the amount оf such a fee is only a permissive subject of bargaining, the Employer is entitled to the information it requested if it is relevant "to bargaining, to the contract or to the parties' pending arbitration."
II. ANALYSIS
Whether a matter is within the realm of "terms and cоnditions of employment," NLRA § 8(d), 29 U.S.C. § 158(d), and is therefore a mandatory subject of bargaining, "is a matter concerning which the Board has special expertise." Our review is concomitantly narrow. We will uphold the Board's decision as long as it is "reasonably defensible." Ford Motor Co. v. NLRB,
Here we find no basis for overturning the Board's conclusion that the amount of an agency fee is not a mandatory subject of bargaining. The Board reasonably construed the obligation to bargain in light of the limitation found in the proviso to § 8(b)(1)(A), which protects "the right of a labor organization to prescribe its own rules with respect to the acquisition or retention of membership therein." That proviso has previously led the Board to the position that "the fees [that a union] imposes are subject to the scrutiny of the Board only in limited situations," Metal Workers' Alliance, Inc.,
The line between the internal аffairs of a union, shielded from Board regulation by § 8(b)(1)(A), and the "terms and conditions of employment," as to which the Board enforces the obligation to bargain, is not always clear. U.O.P. Norplex, Div. of Universal Oil Prods. Co. v. NLRB,
Contrary to the Employer’s argument, the Supreme Court’s decision in
Communications Workers v. Beck,
The Employer in this case voices the concern that it might be charged with an unfаir labor practice if it withholds an excessive fee from an employee’s paycheck, or fires an employee who does not authorize such withholding. This apprehension is at best premature and appears also to be unfounded. If an employee were to object to the amount of the fee to be withheld — a feature notably absent from this case — and were to refuse to authorize the deduction, it appears that, unless the Employer had reason to believe that the fee was unlawful, it would commit no unfair labor practice if, as required by the CBA, it dismissed the employee at the Union’s request.
See H. C. Macaulay Foundry Co. v. NLRB,
The Board has not had occasion, since the decision in Beck, to address the means by which an employee may properly challengе the level of an agency fee. (The non-union employees in Beck successfully sued their union in federal court, asserting that use of their agency fees for purposes other than representation violated the union’s duty of fair representation.) It is surely within the Board’s discretion, however, to conclude that the appropriate mechanism is not for an employer, in bargaining with a union, to appoint itself the representative of some hypothetical non-union employees who may object to the amount of the agency fee set by the union.
Our conclusion that the Board reasonably determined that the amount of a union’s agency fee is not a mandatory subject of bargaining dooms the whole of petitioner’s claim. The duty to bargain imposed by the Act is limited to the mandato
*480
ry subjects captured by the statutory litany of “wages, hours, and other terms and conditions of employment” in § 8(d).
See Borg-Warner,
Of course, an agreement to negotiate about a subject, particularly if it is part of a “trend of industrial practice,” may be “relevant in construing the phrase ‘terms and conditions of employment,’ ”
Ford Motor,
III. CONCLUSION
The Board was reasonable in interpreting the NLRA not to make the amount of the agency fee that a Union charges non-members a mandatory subject of bargaining. And since a non-mandatory subject does not become mandatory by virtue of the parties’ agreement to negotiate or to arbitrate the issue, the Union did not commit an unfair labor practice by refusing to supply information relevant to that subject. The petition for review is therefore
Denied.
