LTV Electrosystems, Inc., urges that its “leadmen” were supervisors, and that the National Labor Relations Board erroneously did not afford the company a hearing on alleged election irregularities and in the unfair labor practice proceeding that resulted in an order to bargain. 1 For these reasons it challenges the Board’s finding that it violated §§ 8(a) (5) and (1) of the act 2 by its refusal to bargain.

*684 After extensive evidentiary hearings, the Board determined that the “leadmen” were not supervisors. We conclude that substantial evidence supports the Board’s finding that these employees were properly included in the bargaining unit.

The Regional Director investigated the charges of election irregularities and found them to be without merit. The company’s exceptions to his report show no substantial and material issues of fact that could be resolved only in a hearing. The company’s request for review was denied by the Board. Under the circumstances, the Board was not required to hold an evidentiary hearing. Macomb Pottery Co. v. NLRB, 376 F.2d 450 (7th Cir. 1967). Nor was an evi-dentiary hearing required in the unfair labor practice proceeding. Cf. Pittsburgh Plate Glass Co. v. NLRB, 313 U.S. 146, 161, 61 S.Ct. 908, 85 L.Ed. 1251 (1941). Summary judgment was appropriate. Neuhoff Brothers, Packers, Inc. v. NLRB, 362 F.2d 611, 613 (5th Cir. 1966), cert, den., 386 U.S. 956, 87 S.Ct. 1027, 18 L.Ed.2d 106 (1967); NLRB v. Puritan Sportswear Corp., 385 F.2d 142, (3rd Cir., Nov. 1, 1967).

The Board’s order will be enforced.

Enforced.
