What does the Americans with Disabilities Act (ADA) require employers to do for employees with disabilities?

Title I of the ADA applies to private employers with 15 or more employees and prohibits discrimination against qualified individuals with disabilities in hiring, firing, pay, and other employment conditions. A 'reasonable accommodation' is any modification or adjustment that allows a qualified employee to perform the essential functions of the job, such as adjusted work schedules, modified equipment, accessible parking, or remote work where feasible. Employers can deny an accommodation only if it would impose an 'undue hardship,' defined as significant difficulty or expense relative to the employer's size and resources. Both physical and mental impairments that substantially limit a major life activity qualify under the ADA.
