N.L.R.B. v. Interboro Contractors, Inc.

In NLRB v. Interboro Contractors, Inc., 388 F.2d 495, 500 (2d Cir. 1967), the Court of Appeals for the Second Circuit stated that the efforts of an individual employee acting alone to enforce the provisions of a collective bargaining agreement may be deemed "concerted," and thus protected, at least when the individual's interpretation of the agreement has a reasonable basis.
