On March 24, the EEOC issued its Final Regulations ("Regulations") implementing Congress's Americans with Disabilities Act Amendments Act of 2008 ("ADAAA"). Although the definition of "disability" remains unchanged under the ADAAA—"a physical or mental impairment that substantially limits one or more major life activities; a record of such an impairment; or being regarded as having a disability"—the new Regulations provide guidance on interpreting these terms. For example, the Regulations provide nine rules of construction that must be applied in determining whether an impairment "substantially limits" a major life activity. These Regulations, available on theFederal Register website, go into effect on May 24, 2011. Employers should review their policies and employee handbooks to ensure they are consistent with the ADAAA.
