In Polish National Alliance v. NLRB, 322 U.S. 643, 64 S.Ct. 1196, 88 L.Ed. 1509 (1944), the Court held that the National Labor Relations Act applied to a fraternal organization providing death, disability and accident benefits to its members and their beneficiaries.
In Borden Co. v. Borella, 325 U.S. 679, precisely the same formulation expressed our conclusion that maintenance employees of a producer-owned office building which was tenanted in part by the producer's central offices, but not by any production facilities, were also within the Act's coverage.
