An employer does not have to eliminate an essential function, i.e., a fundamental duty of the position. "In general, an accommodation is any change in the work environment or in the way things are customarily done that enables an individual with a disability to enjoy equal employment opportunities." "(i) modifications or adjustments to a job application process that enable a qualified applicant with a disability to be considered for the position such qualified applicant desires; or (ii) modifications or adjustments to the work environment, or to the manner or circumstances under which the position held or desired is customarily performed, that enable a qualified individual with a disability to perform the essential functions of that position; or (iii) modifications or adjustments that enable a covered entity's employee with a disability to enjoy equal benefits and privileges of employment as are enjoyed by its other similarly situated employees without disabilities." The duty to provide reasonable accommodation is a fundamental statutory requirement because of the nature of discrimination faced by individuals with disabilities.

Reassignment issues addressed include who is entitled to reassignment and the extent to which an employer must search for a vacant position. The Guidance also examines issues concerning the interplay between reasonable accommodations and conduct rules.
