An applicant charges that your company has failed to comply with the provisions of the ADA because you discriminated against him for a room attendant position. Selection criteria for this position stipulated that an applicant must be able to successfully make beds, wash out sinks and bathtubs, and vacuum floors. The applicant believes that the employer is required to rewrite the job description so that some parts of this job, which are not actually essential functions, can be performed by others. Is he correct? Why or why not?
