The Illinois Human Rights Act (IHRA) prohibits employment practices that discriminate based on race, color, religion, sex (including sexual harassment), national origin, ancestry, age (40 years and older), order of protection status, marital status, disability, military status, sexual orientation, unfavorable discharge from military service, arrest record, citizenship status, or pregnancy (including childbirth or related medical conditions). The Act covers all public employers, all public contractors, and private employers with 15 or more employees for 20 or more weeks during the calendar year of the alleged violation or during the preceding calendar year. However, the disability, pregnancy, and sexual harassment provisions of the Act cover all employers, regardless of size (IL Comp. Stat. Ch. 775 Sec. 5/1-101 et seq.).
