Effective January 1, 2009, the definition of an individual with a “disability” as defined under both the Rehabilitation Act and the Americans with Disabilities Act (ADA) will be significantly expanded. This is due to the passage of the ADA Amendments Act (ADAAA) that sets new standards for determining disability status. Managers, supervisors and the Reasonable Accommodation Committees (RACs) need to be aware of the extent of the changes in the ADAAA so they can assess requests for reasonable accommodation in accordance with these new standards.

Although the Equal Employment Opportunity Commission (EEOC) will issue regulations implementing these new provisions, the regulations will not be published by January 1.Nonetheless, employers must still comply with the law. Consequently, we are providing you with the attached synopsis of the changes in the law so that you are fully informed about the new standards and for use as a guide in making reasonable accommodation decisions.
