Persons with disabilities are protected by the ADA/The Americans with Disabilities Act. The ADA helps to ensure that people with disabilities are given equal opportunity for employment.
It is unlawful for any employer to discriminate against any person who has a disability. It is the responsibility of the employer to make REASONABLE accommodations to the disabled employee.
Law's are really good for people with disabilities. You can not be discriminated against. If you can do the given job, then you should be able to work anywhere.
