Yes. Under these circumstances, the employer violated the Americans with Disabilities Act (ADA) by refusing to hire Arnold because of his association with an individual with a disability. Although federal equal employment laws do not prohibit discrimination against caregivers per se, the Equal Employment Opportunity Commission (EEOC) has described circumstances where discrimination against caregivers might constitute unlawful disparate treatment under the ADA.
In addition to prohibiting discrimination against a qualified worker because of his or her own disability, the ADA prohibits discrimination because of the disability of an individual with whom the worker has a relationship or an association, such as a child, spouse, or parent. Under this provision, an employer may not treat a worker less favorably based on a stereotypical assumption about the worker’s abilities to perform job duties satisfactorily while also providing care to a relative or other individual with a disability.
