(concurring).
I concur in the result. I do not join in the statement that it is not an unfair labor practice for an employer to address his employees in working hours if only the employer permits union solicitation in nonworking hours. We need not here decide that issue; much can be said for an opposite conclusion in the light of our opinion in Bonwit Teller, Inc. v. N. L. R. B., 2 Cir., 197 F.2d 640.
