Veronica is a repair person for Wind Power Company. The job requires traveling to remote areas to make repairs to windmills, transmission towers, and power stations under any conditions. Veronica has had the job longer than other employees. Veronica applies for a promotion to a supervisory position that requires constant communication with others in the field. Wind Power rejects the application on the ground that Veronica is hearing impaired. Wind Power acknowledges that Veronica is otherwise qualified, but asserts that it “needs someone who does not have a hearing problem.” Veronica files a suit against Wind Power under the Americans with Disabilities Act. What is the issue, and what are the relevant considerations on which its resolution depends?
