“[T]he job description states that the supervisor ‘may perform manual labor’ . . . . Just because . . . the supervisor sometimes ‘may perform’ such labor does not override the consideration that the ability to perform physical labor is not an essential or even mandatory component of the supervisor’s job. Therefore, [Plaintiff]’s inability to walk is not fundamentally inconsistent with [Plaintiff]’s assertion that he was qualified for his position.” Patterson, 847 F. Supp. 2d at 942.
