The Iowa Civil Rights Act prohibits employment discrimination based on age (18 years and older), race, creed, color, sex (including pregnancy and childbirth), sexual orientation, gender identity, national origin, religion, or disability (including HIV and AIDS), unless such factors are relevant to the job in question. The law specifically prohibits employers from advertising or publishing discriminatory employment preferences unless the factors indicated are necessary for job performance (a bona fide occupational qualification (BFOQ)). Employers may advertise and reserve positions specifically for individuals with disabilities, provided other suitable employment opportunities are available for individuals without disabilities. The Act applies to all public and private employers with four or more employees (IA Code Sec. 216.1 et seq.).
