Final answer:
The employer's use of medical records to decide if a patient is disabled falls under the Americans with Disabilities Act (ADA) which prohibits discrimination against individuals with disabilities and requires reasonable accommodations for them on the job.
Step-by-step explanation:
The employer's use of medical records to decide whether or not a patient is disabled is a part of the employment process and falls under the Americans with Disabilities Act of 1990 (ADA) which prohibits discrimination against individuals with disabilities. According to the ADA, employers are required to make reasonable accommodations for qualified individuals with disabilities and not discriminate against them based on their disability. In this case, the employer would need to review the medical records to determine if the individual qualifies as disabled and whether any accommodations can be made to support their employment.
