These employers do have to give "reasonable accommodations" to workers with disabilities if needed. An "accommodation" is a change in the way things are usually done. It is a change that a worker needs because of a disability, to help them do their job. If a worker with a disability needs reasonable accommodations to do their job, that does not mean they are not qualified to do their job. As long as the worker is able to do their job with the help of accommodations, they are qualified to do the job.
