In Nolde Bros. Inc. v. Bakery Workers (1977) 430 U.S. 243, after termination of its contract, the union sought to compel the employer to arbitrate a dispute over the meaning of the "severance pay" clause in the agreement. The court held that parties to a collective bargaining agreement may agree that rights accrued during the term of the agreement shall be realized after its expiration. ( Id., at p. 249.) "The dispute therefore, although arising after the expiration of the collective-bargaining contract, clearly arises under that contract." ( Id., at p. 249.)
