Can a supervisor ask how an applicant will perform a job with or without accommodation?

Yes, a supervisor can inquire about how an applicant would perform a job with or without accommodation, but the questions must be carefully framed to avoid discrimination. They should focus on the essential functions of the job and the applicant’s ability to perform those functions, rather than delving into the applicant's disability or medical history. It's important that any inquiries comply with employment laws, such as the Americans with Disabilities Act (ADA), which protects against discrimination based on disability.
