This case arises upon the petition of the National Labor Relations Board seeking enforcement of the decision and order of the Board, which, among other things,1 ordered the reinstatement with back pay of two suspended employees of respondent. Respondent contends that there is no substantial evidence to sup*355port the findings and conclusions of the NLRB.2

The administrative law judge found, among other things, that respondent’s discharge of Aaron Cole and its indefinite suspension of Marie Cash3 were discriminatory and unfair labor practices within the meaning of § 8(a)(3)4 of the National Labor Relations Act and interfered with § 7 rights of its employees, in violation of § 8(a)(1) 5 of the act. The law judge’s order that Cole and Cash be reinstated with back pay and that respondent terminate its anti-union activities was adopted6 by the Board.

It is our conclusion that, although the evidence is in sharp conflict, this case involves credibility judgments that are best resolved by the trier of fact and the agency that possesses expertise in this area. Accordingly, since there is substantial evidence to support the findings, conclusions and order of the Board, and no other reasons having been shown to disestablish the validity of these actions, the order is due to be enforced. See, e. g., Bowman Transportation, Inc. v. Arkansas Best Freight System, Inc., 419 U.S. 281, 95 S.Ct. 438, 42 L.Ed.2d 447, 454-55 (1974); Universal Camera Corp. v. NLRB, 340 U.S. 474, 485-86, 71 S.Ct. 456, 463, 95 L.Ed. 456, 466-67 (1951); NLRB v. Pearl Bookbinding Co., 517 F.2d 1108, 1112 (1st Cir. 1975); NLRB v. R. L. Sweet Lumber Co., 515 F.2d 785, 793 (10th Cir. 1975).
