Question: Boxer Mike Tyson hired Rooney as his trainer, the term of the contract being "for as long as [Tyson] fought professionally." Tyson fired Rooney while Tyson was still boxing, and Rooney sued for breach of contract. Tyson claimed that the term of the contract was so indefinite that it was an "at-will" contract so that he could fire Rooney at any time. Who is correct? (Rooney v. Tyson, 91 N.Y.2d 685)
