11.11 Age Discrimination-Defenses-Reasonable Factor Other than Age: Reasonable factor other than age (RFA) is a defense to a charge of age discrimination under the Age Discrimination in Employment Act (AREA). Under the AREA, it is unlawful for an employer to discriminate against an employee or job applicant due to their age, unless the employer can demonstrate that the decision is based on factors other than age. An employer who can prove that the age difference is based on an RFA may be able to successfully defend themselves in a case of age discrimination. The types of Road that employers may use to defend themselves in an age discrimination case include skills, experience, education, training, and physical capability. Other factors that are not considered age-related, such as criminal background, work history, and qualifications may also be taken into consideration. Additionally, an employer may be able to provide evidence that the decision was based on a legitimate business need, such as promoting a more qualified candidate or avoiding a potential liability. In order to successfully defend themselves in an age discrimination case, employers must demonstrate that their decision was based on an RFA and not on an age-related factor. Employers must also be able to show that the RFA was necessary for the successful operation of their business. If an employer cannot prove that their decision was based on an RFA, they may be liable for age discrimination.
