Does the ADA prohibit disability based harassment in the workplace?

Yes, employees can sue for disability based harassment under the Rehabilitation Act (if they are federal employees) and the ADA. To prevail on a disability harassment claim, an employee must show: (1) that he or she is disabled within the meaning of the law; (2) that he or she was subjected to a hostile workplace environment; and (3) that hostility was directed at the employee because of his or her disability.
