Employment discrimination against individuals with disabilities is prohibited. This includes applicants for employment and employees. An individual is considered to have a "disability" if s/he has a physical or mental impairment that substantially limits a major life activity, has a record of such an impairment, or is regarded as having such an impairment. Persons discriminated against because they have a known association or relationship with an individual with a disability also are protected.
I hope that help you out that a little hard question.
