The ADA requires that employers post a notice describing the provisions of the ADA. It must be made accessible, as needed, to individuals with disabilities. A poster is available from EEOC summarizing the requirements of the ADA and other Federal legal requirements for nondiscrimination for which EEOC has enforcement responsibility. EEOC also provides guidance on making this information available in accessible formats for people with disabilities.
