A Postal Service carrier was fired for losing a key that opened every one of her customer's mailboxes. She did not hear her key drop while on her route because of a her profound hearing loss, something she noted on her employment application. The key was later discovered and turned in by a customer. Was this a violation of ADA law? No, because there was no "reasonable accommodation" required of the employer. This is typically considered the legel test as to whether the Americans with Disabilities Act has been violated or not.
