Probably not. These alternatives are not effective because they do not allow Willie to ask questions and participate in discussions during the regular staff meetings as other employees do. The Americans with Disabilities Act (ADA) requires employers to provide adjustments or modifications (reasonable accommodations) that enable applicants and employees with disabilities to enjoy equal employment opportunities unless doing so would be an undue hardship – that is, a significant difficulty or expense. If more than one accommodation would be effective, the employee’s preference should be given primary consideration, although the employer is not required to provide the employee’s first choice of reasonable accommodation. If the requested accommodation is too difficult or too expensive, an employer may choose to provide an easier or less costly accommodation as long as it is effective in meeting the employee’s needs. In this situation, absent undue hardship, the employer must provide a sign language interpreter for the staff meetings.
