Job restructuring is a form of reasonable accommodation which enables many qualified individuals with disabilities to perform jobs effectively. Job restructuring as a reasonable accommodation may involve reallocating or redistributing the marginal functions of a job. However, an employer is not required to reallocate essential functions of a job as a reasonable accommodation. Essential functions, by definition, are those that a qualified individual must perform, with or without an accommodation.
An employer may exchange marginal functions of a job that cannot be performed by a person with a disability for marginal job functions performed by one or more other employees.
Although an employer is not required to reallocate essential job functions, it may be a reasonable accommodation to modify the essential functions of a job by changing when or how they are done.
