11.6 Age Discrimination-Defenses are strategies used by employers to protect against potential age discrimination claims. These strategies are used to show that the decision made was based on factors other than age. Some of the most commonly used defenses are: Bona Fide Occupational Qualification (BFO) defense, Seniority System defense, Reasonable Factors Other Than Age (RFA) defense, Business Necessity defense, and the Same Terms and Conditions defense. The BFO defense is used to show that age is a necessary factor for a job and that the employment decision was made based on the individual's ability to perform the job. The Seniority System defense is used to show that the employer had a legitimate policy of using seniority or age as criteria for employment decisions. The RFA defense is used to show that age was not the only factor in the decision and that other reasonable criteria were used. The Business Necessity defense is used to show that the employer had a legitimate business need for the decision made and that the decision was made in a nondiscriminatory manner. The Same Terms and Conditions defense is used to show that the employer offered the same terms and conditions to all employees regardless of age.
