The New York National Guard1 petitions for review of an order of the Federal Labor Relations Authority (FLRA) which directs the Guard to pay the per diem and travel expenses incurred by representatives of civilian employees in collective bargaining with the Guard. The FLRA applies for enforcement of the order. We grant the petition for review and deny enforcement. We find no authority to support the FLRA’s command that the federal government, alone among federally-regulated employers, must pay expenses incurred by its adversaries across the bargaining table.
The parties agree on the facts. The National Guard employs some 46,700 civilian technicians across the country to meet the day-to-day administrative, training and logistical needs of the Guard.2 Approximately three-quarters of the technicians are represented by various unions, including the New York State Council of Association of Civilian Technicians, Inc. On two days in *47November 1979, and one day in April 1980, five members of the New York State Council represented their union in contract negotiations with the New York National Guard in Albany, New York. The technicians incurred travel and per diem expenses because they were not stationed in Albany. The Guard’s principal negotiator incurred similar expenses. The Guard paid the expenses of its own negotiator but pursuant to its past practice declined to pay the expenses of the Union representatives. The Union filed unfair labor practice charges in spring of 1980 with the FLRA, and in December 1981 the FLRA found that the Union representatives were entitled to their travel/per diem costs under a previously issued FLRA Interpretation and Guidance, 2 FLRA No. 31 (1979).
The FLRA’s Interpretation was not a regulation promulgated under 5 U.S.C. § 7134, but rather an informal ruling issued under 5 U.S.C. § 7105(a)(1). The FLRA in its Interpretation noted that government employees are entitled to reimbursement of travel and per diem expenses incurred on official business:
(a) Under regulations prescribed under § 5707 of this title, an employee while traveling on official business away from his designated post of duty ... is entitled to ... is entitled to ... a per diem allowance ....
5 U.S.C. § 5702(a) (1976) (emphasis added).
The FLRA also noted that the Civil Service Reform Act of 1978 (CSRA) provided that government employees would draw their salaries for time spent in collective bargaining by designating such time as official time:
(a) Any employee representing an exclusive representative in the negotiation of a collective bargaining agreement under this chapter shall be authorized official time for such purposes.
P.L. 95-454, 95th Cong., 2d Sess. § 701, 92 Stat. 1111, 1214 (1978), 5 U.S.C. § 7131(a) (Supp. Ill 1979) (emphasis added).
Government employees had previously conducted collective bargaining under Executive Order 11491 (1969), 1969 U.S.Code Cong. & Ad.News 2948, which did not entitle employees to pay for time spent in collective bargaining. The FLRA concluded that when Congress expanded “official time” to compensate employees for bargaining time, Congress also meant to expand “official business” to compensate employee bargainers for travel and per diem expenses. The FLRA supported its conclusion by noting that Congress in the CSRA had declared that collective bargaining furthered the public business:
(a) The Congress finds that — (1) experience in both private and public employment indicates that the statutory protection of the right of employees to organize, bargain collectively, and participate through labor organizations of their own choosing in decisions which affect them—
(A) safeguards the public interest,
(B) contributes to the effective conduct of public business. ...
P.L. 95—454, 95th Cong., 2d Sess. § 701, 92 Stat. 1111, 1192 (1978), 5 U.S.C. § 7101(a) (Supp. III 1979) (emphasis added).
The FLRA held that collective bargaining done on official time, which contributed to the effective conduct of public business, was “official business” within the meaning of 5 U.S.C. § 5702(a) and therefore employees engaged in collective bargaining were entitled to per diem. The National Guard, one of the first federal employers to suffer the consequences of the FLRA’s Interpretation & Guidance,3 argues the FLRA incorrectly interpreted the relevant statutes. We agree.
*48Our review of the FLRA’s decision is not inhibited by the deference normally due the Authority’s construction of its enabling statute. See Internal Revenue Service v. Federal Labor Relations Authority, 671 F.2d 560, 563 (D.C.Cir.1982). Here the FLRA’s decision rests on an interpretation of “official business” in 5 U.S.C. § 5702(a) —a section not part of the CSRA, which created the FLRA, but instead part of a subchapter administered by the General Services Administration. 5 U.S.C. § 5707. No great deference is due an agency interpretation of another agency’s statute. See New Jersey Air Nat’l Guard v. Federal Labor Relations Authority, 677 F.2d 276, at 281 n. 6 (3rd Cir. 1982).
We are cited to no legislative history supporting the FLRA’s conclusion that collective bargaining on “official time” is also “official business.” The FLRA relies instead on the Congressional finding that collective bargaining is in the public interest. Such a general declaration of policy is “too thin a reed” to support a substantive ruling which would cost the federal government substantial sums of money in per diem and travel expenses. Cf. Pennhurst State School v. Halderman, 451 U.S. 1, 19, 101 S.Ct. 1531, 1541, 67 L.Ed.2d 694 (1981) (statute’s “bill of rights” for the handicapped does not create affirmative obligations on the states to treat the handicapped).
Moreover, the FLRA’s extrapolation goes too far. Congress did not find that collective bargaining furthers the public interest. Congress found that statutory protection of collective bargaining furthers the public interest, see 5 U.S.C. § 7101(a) and CSRA § 3(10), 92 Stat. 1111, 1113 (1978). The import of the distinction becomes clear upon consideration of the legislative history of CSRA § 3(10), because the history indicates that Congress did not endorse collective bargaining as in the public interest. Congress merely stated that collective bargaining was not against the public interest and did not hamper public business:
The conference substitute ... adopts the Senate language which states as one of the policies of the United States that the right of Federal employees to ... bargain collectively ... with full regard for the public interest and the effectual conduct of public business, should be specifically recognized in statute.”
Conference Report, H.R.Rep.No. 1717, 95th Cong. 2d Sess. 127 (1978), 1978 U.S.Code Cong. & Ad.News 2723, 2860. The same sentiments were expressed in the Senate Report:
[Section 3(10)] states findings of Congress that the protection of the right of employees to ... bargain collectively . .. can be accomplished with full regard for the public interest and contributes to the effective conduct of public business.
S.Rep.No. 969, 95th Cong. 1st Sess. 97 (1977), 1978 U.S.Code Cong. & Ad.News 2723, 2819 (emphasis added).
The reports indicate that Congress did not give collective bargaining the blanket endorsement that FLRA claims to have found in the statute. Moreover, the endorsement of collective bargaining was no more than the endorsement previously contained in Executive Order 11491. See S.Rep.No. 969, supra, at 17, 1978 U.S.Code Cong. & Ad.News at 2739.
Finally, though neither side saw fit to refer us to comparable practice in the private sector, we think it appropriate to note that the expense the FLRA would impose as routine upon the federal government is viewed as an extraordinary remedy by the National Labor Relations Board (NLRB). Only a decade ago, the NLRB held that it was without power to order a private employer to pay the costs of a breakdown in collective bargaining. Ex-Cell-O Corp., 185 N.L.R.B. 107 (1970). The D.C. Circuit remanded on the ground that the NLRB did have such power, International Union v. National Labor Relations Board, 449 F.2d 1046 (D.C.Cir.1971) (per curiam), but that power has been exercised to compel payment of employee bargainers’ per diem and travel expenses only as an extraordinary remedy for the employers’ failure to bargain in good faith. Marriott In-Flite Services, 258 N.L.R.B. No. 99 (Sept. 30, 1981); J. P. Stevens & Co., Inc., 239 N.L.R.B. 738, 773 *49(1978). Far from seeking a remedy for bad faith bargaining, the FLRA would hold that the federal government must always pay the bargaining costs of its adversaries. One of the obvious and universal purposes of collecting union dues is to pay for the expenses of such important activities as collective bargaining with the employer. Under all the circumstances we cannot believe that Congress meant the government to assume such an unusual burden, so different from any accepted practice in dealings between employers and employees, absent a clear and specific provision to that effect.
Petition granted; enforcement denied.
. The New York National Guard, although a state militia, is federally administered under Title 32 of the United States Code by the National Guard Bureau in the Pentagon, 10 U.S.C. § 3015 (1976). Therefore a division of the Department of Defense is petitioner here as the administrator of the New York National Guard.
. National Guard technicians are federal employees. 32 U.S.C. § 709(d) (1976).
. Several other federal employers have challenged the FLRA’s Interpretation & Guidance in similar cases before courts of appeals: Bureau of the Mint v. Federal Labor Relations Authority, 81-1194; 82-1195 (D.C.Cir.); Department of Agriculture v. FLRA, 81-1948 (8th Cir.); Florida National Guard v. FLRA, 81-5466 (11th Cir.).
The Ninth Circuit upheld the FLRA’s determination that federal employers must pay the per diem and travel expenses of federal employee bargainers. Bureau of Alcohol, Tobacco & Firearms v. FLRA, 672 F.2d 732, 737-38 (9th Cir. 1982). We disagree.
