In Lutheran Hospital of Milwaukee, Inc. v. N.L.R.B., U.S. 98 S.Ct. 3118, 57 L.Ed.2d 1145 (1978), the Supreme Court vacated and remanded the judgment of the Seventh Circuit for further consideration in the light of Beth Israel Hospital v. N.L.R.B., 437 U.S. 483, 98 S.Ct. 2463, 57 L.Ed. 370 (1978). The Supreme Court had noticed in Beth Israel that the order enforced in Lutheran extended beyond the cafeteria to other areas of the hospital. See Beth Israel Hospital v. N.L.R.B., supra, 98 S.Ct. at 2467 n.5.
