The process of developing job descriptions often sheds light on the nature of a job as well as suggests that there are alternative methods of performing essential job tasks. Job analysis may help encourage management and staff to work together in identifying and streamlining the essential and marginal job functions.
According to the ADA, an employer may not ask disability-related questions and may not conduct medical examinations until after it makes a conditional job offer to the applicant (EEOC, 1995). An individual, as an applicant or a current employee, may wish to disclose that s/he has a disability and needs an accommodation, but is uncertain whether disclosure is possible or advisable. Including a brief and accurate statement in the job description about the employer’s responsibility and the individuals rights may help initiate the interactive process between an employer and an individual with a disability. If an individual is qualified to perform essential job functions except for limitations caused by a disability, the employer must consider whether the individual could perform these functions with a reasonable accommodation. An employer is not required to reallocate the essential functions of a job as a reasonable accommodation.
