Workplace Accommodation under the Americans with Disabilities Act. A reasonable accommodation is any change to the application or hiring process, to the job, to the way the job is done, or the work environment that allows a person with a disability who is qualified for the job to perform the essential functions of that job and enjoy equal employment opportunities. Accommodations are considered “reasonable” if they do not create an undue hardship or a direct threat.In order to determine what is reasonable, an employer must look at the request made by the applicant or employee with a disability. Whether or not an accommodation is reasonable will vary according to the position the employee holds, the way their disability affects their ability to do their job, and the environment that they work in.
