The Age Discrimination in Employment Act (ADEA), 29 U.S.C. § 621 et seq., protects workers aged forty or older from employment discrimination on the basis of their age.
Because of the numerous similarities between the ADEA and Title VII, the instructions in this chapter generally mirror the committee’s organization of Title VII instructions by theory of liability, as used in Chapter 10 ("Civil Rights—Title VII—Employment Discrimination; Harassment; Retaliation"). As with Title VII, the ADEA recognizes claims under both disparate treatment and disparate impact theories of liability. See Smith v. City of Jackson, 544 U.S. 228, 232–34 (2005). The committee recommends that the court first identify the theory under which the plaintiff has asserted an ADEA claim, and then refer to the relevant subchapter for applicable jury instructions.
"The ADEA and Title VII share common substantive features and also a common purpose: ‘the elimination of discrimination in the workplace.’" McKennon v. Nashville Banner Publ’g Co., 513 U.S. 352, 358 (1995) (quoting Oscar Mayer & Co. v. Evans, 441 U.S. 750, 756 (1979)). Further, certain "language in the ADEA . . . was ‘derived in haec verba from Title VII.’" Smith, 544 U.S. at 234. On issues where the ADEA and Title VII are in substantial accord, appropriately modified Title VII instructions should be given, as cross-referenced in this chapter. See Comments to Instructions 11.2 (Age Discrimination—Hostile Work Environment); 11.3 (Age Discrimination—Retaliation); 11.5 (Age Discrimination—Definition of Common Terms); 11.6A (Age Discrimination—Defenses—Bona Fide Occupational Qualification); 11.6B (Age Discrimination—Defenses—After-Acquired Evidence), and 11.6C (Age Discrimination—Defenses—Bona Fide Seniority System).
The ADEA and Title VII are not identical. A brief summary of their differences is set forth below.
Mixed Motives: A Title VII plaintiff need only prove that a protected status was "a motivating factor" for an adverse employment action. Desert Palace, Inc. v. Costa, 539 U.S. 90, 101 (2003). However, "textual differences between Title VII and the ADEA . . . prevent . . . [application of] Desert Palace to federal age discrimination claims." Gross v. FBL Financial Services, Inc., 557 U.S. 167, 175 fn. 2 (2009). In Gross, the Court held "a plaintiff bringing a disparate-treatment claim pursuant to the ADEA must prove, by a preponderance of the evidence, that age was the ‘but-for’ cause of the challenged adverse employment action. The burden of persuasion does not shift to the employer to show that it would have taken the action regardless of age, even when a plaintiff has produced some evidence that age was one motivating factor in that decision." Id. at 180. Thus, it was reversible error to instruct the jury using Title VII’s "a motivating factor" formulation. Id. Earlier Ninth Circuit cases applying the same standards to cases proceeding on disparate treatment or retaliation theories under the two statutes must now be read carefully in light of Gross. See generally Coleman v. Quaker Oats Co., 232 F.3d 1271, 1295 (9th Cir.2000) ("The analysis under Title VII is the same as that under ADEA."); Mustafa v. Clark County Sch. Dist., 157 F.3d 1169, 1180 n.11 (9th Cir.1998) ("This Court applies the same standards to disparate treatment claims pursuant to Title VII [and] the Age Discrimination in Employment Act . . . ."); O’Day v. McDonnell Douglas Helicopter Co., 79 F.3d 756, 763 (9th Cir.1996) ("Section 623(d) is the ADEA equivalent of the anti-retaliation provision of Title VII."). See Instructions 11.2 (Age Discrimination—Hostile Work Environment), 11.3 (Age Discrimination—Retaliation).
Disparate Impact: After longstanding uncertainty on the issue, Smith held that an ADEA claim can be predicated on a disparate impact theory. 544 U.S. at 240. However, the Court held that because the Civil Rights Act of 1991 did not amend the ADEA, the pre-1991 heightened disparate impact standard applies. Id. (citing Wards Cove Packing Co. v. Atonio, 490 U.S. 642 (1989)). Thus, in order to prove a disparate impact claim, plaintiffs must identify a "specific test, requirement, or practice . . . that has an adverse impact on older workers." Id. See Instruction 11.4 (Age Discrimination—Disparate Impact—Elements).
Defenses: Unlike race or gender, certain business costs correlate directly with age. Thus, the ADEA permits an affirmative defense for certain actions related to the cost of non-compensation employment benefits. 29 U.S.C. § 623(f)(2)(B). See Instruction 11.6D (Age Discrimination—Defenses—Bona Fide Employee Benefit Plan).
The ADEA’s bona fide seniority system defense imposes the additional requirement, not found in the Title VII context, that the seniority system may not "require or permit . . . involuntary retirement[.]" 29 U.S.C. § 623(f)(2)(A). See Instruction 11.6B (Age Discrimination—Defenses—Bona Fide Seniority System).
Generally in a disparate impact case, the ADEA provides a broad defense when the employer’s action is based on a reasonable factor other than age. 29 U.S.C. § 623(f)(1). This is substantially broader than the "business necessity" defense afforded by Title VII. See Smith, 544 U.S. at 243 ("Unlike the business necessity test, which asks whether there are other ways for the employer to achieve its goals that do not result in a disparate impact on a protected class, the [reasonable factor other than age] inquiry includes no such requirement."). See Instruction 11.6E (Age Discrimination—Defenses—Reasonable Factor Other than Age).
Remedies: The remedies provision in the ADEA is borrowed from a wholly different body of law—the Fair Labor Standards Act ("FLSA"). See Lorillard v. Pons, 434 U.S. 575, 582 (1978) ("[Other than] those changes Congress expressly made, it intended to incorporate fully the remedies and procedures of the FLSA."). This creates substantial differences in damages instructions. See Comment to Instruction 11.7A (Age Discrimination—Damages—Back and Front Pay—Mitigation). Thus, the ADEA provides the FLSA’s remedies of back pay, liquidated damages and injunctive relief. Additionally, front pay may be awarded in lieu of reinstatement if the court finds that reinstatement is not a feasible remedy. Cassino v. Reichhold Chems., Inc., 817 F.2d 1338, 1347 (9th Cir.1987) (ADEA case).
The ADEA does not provide for non-wage compensatory damages, such as damages for emotional distress, or for punitive damages. See Cancellier v. Federated Dept. Stores, 672 F.2d 1312, 1318 (9th Cir.1982) (no punitive damages); Naton v. Bank of Cal., 649 F.2d 691, 698 (9th Cir.1981) (no non-wage compensatory damages); compare 42 U.S.C. § 1981a(a)(1) (permitting recovery of compensatory and punitive damages under Title VII). See Instructions 11.7A (Age Discrimination—Damages—Back and Front Pay—Mitigation), and 11.7B (Age Discrimination—Damages—Willful Discrimination—Liquidated Damages).
Because the ADEA’s remedies analogue is the FLSA, not Title VII, the ADEA provides for a jury trial on the issue of back pay. See Lorillard, 434 U.S. at 582–84; compare Lutz v. Glendale Union High Sch., 403 F.3d 1061, 1067–68 (9th Cir.2005) (plaintiff not entitled to jury determination of Title VII back pay award). On the question of whether or not front pay is an issue for the court or for the jury, see Traxler v. Multnomah County, 596 F.3d 1007 (9th Cir. 2010), and Cassino v. Reichold Chemicals, 817 F.2d 1338 (9th Cir. 1987).
