In N.L.R.B. v. International Ass'n of Bridge, Etc., 549 F.2d at 641, we enforced an order of the N.L.R.B. based on the N.L. R.B. finding that an employer was not bound by a jurisdictional decision of the AFL-CIO dispute board because the employer had not expressly consented to be bound and had not participated in the submission of the dispute to that body.
