What is the test for an employer to fail to accommodate a plaintiff with a disability?

1. Failure to Accommodate. To establish a failure-to-accommodate claim, a plaintiff must show "(1) that he is an individual who has a disability within the meaning of the statute, (2) that an employer covered by the statute had notice of his disability, (3) that with reasonable accommodation, he could perform the essential functions of the position sought, and (4) that the employer has refused to make such accommodations." Stone v. City of Mount Vernon, 118 F.3d 92, 96-97 (2d Cir. 1997).
