OPINION

The case is before the Court on the application of the National Labor Relations Board, pursuant to Section 10(e) of the National Labor Relations Act, as amended (29 U.S.C. § 151 et seq.), for enforcement of its order, issued January 26, 1973, against R. W. Little, Inc. The Board’s Decision and Order are reported at 201 NLRB No. 71. The unfair labor practices occurred in San Diego, California, where the Company is a contractor •engaged in sandblasting and painting.

In brief, the Board found that the Company violated Section 8(a)(3) and (1) of the Act by discharging two employees because of their grievance activity pursuant to the collective-bargaining agreement between the Company and their Union.

In reviewing the order and record in this matter we must have in mind the limitations on such review and that questions of credibility are for the administrative law judge who has had the opportunity to observe the demeanor of the witnesses. N.L.R.B. v. Thrifty Supply Company, 364 F.2d 508, 509 (9th Cir. 1966). As stated by the Court in N.L.R.B. v. Walton, Mfg. Co., 369 U.S. 404, 408, 82 S.Ct. 853, 855, 7 L.Ed.2d 829 (1962), the judge

“sees the witnesses and hears them testify, while the Board and the reviewing court look only at cold records.”

The Court concludes that upon the record considered as a whole there is substantial evidence to support the findings of the Board as to. the unfair labor practices in question.

The Order of the Board will be enforced.
