Equal employment opportunity for individuals with disabilities--EEOC. Final rule

On July 26, 1990, the Americans With Disabilities Act (ADA) was signed into law. Section 106 of the ADA requires that the Equal Employment Opportunity Commission (EEOC) issue substantive regulations implementing title I (Employment) within one year of the date of enactment of the Act. Pursuant to this mandate, the Commission is publishing a new part 1630 to its regulations to implement title I and sections 3(2), 3(3), 501, 503, 506(e), 508, 510, and 511 of the ADA as those sections pertain to employment. New part 1630 prohibits discrimination against qualified individuals with disabilities in all aspects of employment.
