In Illinois, discrimination in a workplace refers to discriminating against employees on the basis of their race, color, ancestry, religion, gender, national origin, age, marital status, citizenship status, sexual orientation, gender-related identity, pregnancy, military status, or physical/mental disability.
Such discrimination is strictly prohibited.
Employers are also prohibited from engaging in actions such as unequal pay, demotions, failure to promote, unequal benefits, workplace harassment, retaliation, and unequal terms and conditions of employment.
