Sexual Harassment Laws in Illinois: Your Rights at Work

Title VII of the Civil Rights Act of 1964 (42 U.S.C. § 2000e) prohibits employment discrimination based on sex, which includes sexual harassment. The U.S. Equal Employment Opportunity Commission (EEOC) enforces Title VII and defines sexual harassment as unwelcome sexual advances, requests for sexual favors, and other verbal or physical conduct of a sexual nature when:

(1) submission to such conduct is made either explicitly or implicitly a term or condition of employment; (2) submission to or rejection of such conduct is used as the basis for employment decisions affecting the employee; or (3) such conduct has the purpose or effect of unreasonably interfering with work performance or creating an intimidating, hostile, or offensive working environment.

Title VII covers employers with 15 or more employees. Federal law provides for compensatory damages for lost wages and emotional distress, punitive damages against employers who act with malice or reckless indifference, attorney fees and costs, and injunctive relief. The federal filing deadline is 180 days from the harassment in non-deferral states, but 300 days in deferral states like Illinois where a state agency processes charges first.

Illinois law is substantially similar to and in some respects broader than federal Title VII. The Illinois Human Rights Act (775 ILCS 5/1-101 et seq.) prohibits sexual harassment by employers, employees, and non-employees (including contractors, vendors, and clients) in the course of employment. Sexual harassment includes unwelcome conduct of a sexual nature, unwelcome sexual advances, requests for sexual favors, and other conduct based on sex that interferes with work or creates a hostile, offensive, or abusive work environment.

Illinois covers all employers with one or more employees, not just those with 15 or more. This is significantly broader than Title VII. The Act applies to all aspects of employment: hiring, termination, compensation, training, advancement, and other terms and conditions of employment. Illinois requires employers with 15 or more employees to have a written sexual harassment policy and provide annual training on harassment prevention to all employees and supervisors (775 ILCS 5/8A-101 et seq.).

Uniquely, Illinois protects employees from harassment by non-employees (clients, vendors, customers) if the employer knew or should have known of the conduct and failed to take prompt corrective action. Sexual orientation discrimination and gender identity discrimination are explicitly protected under Illinois law, even though Title VII's coverage of these categories has developed more recently through EEOC guidance and court interpretation.

Remedies under Illinois law include back pay, front pay, compensatory damages for emotional distress, punitive damages up to $100,000, attorney fees and costs, and reinstatement. The Illinois Department of Human Rights investigates charges for free and can issue right-to-sue letters or pursue administrative hearings before the Illinois Human Rights Commission.

Sexual harassment does not apply to consensual relationships between adults with no power imbalance, though employers may restrict supervisor-subordinate relationships. Harassment must be unwelcome; if an employee welcomes the conduct, no violation occurs, though welcome cannot be inferred from the employee's failure to object.

However, Illinois law recognizes that consent is not a valid defense if there is a power imbalance or if the employee reasonably feared retaliation or job consequences for refusing the conduct. Isolated, minor incidents do not rise to the level of harassment; the conduct must be severe or pervasive enough to interfere with employment or create a hostile environment.

Employers have an affirmative defense if they exercised reasonable care to prevent harassment and the employee unreasonably failed to report it through internal channels. However, this defense does not apply if the harasser is the employee's supervisor or if the employer actually knew of the conduct. Federal and state employer liability differs: if the harassment is quid pro quo (conditioning employment benefits on sexual conduct), the employer is strictly liable. If it is a hostile work environment, the employer is liable if it knew or should have known of the harassment and failed to take prompt corrective action.

At-will employment doctrine does not shield employers from harassment liability; even at-will employees are protected. Union-represented employees have the same protections under state law, and the collective bargaining agreement does not override statutory protections against harassment.

Step 1: Document the Harassment. Keep detailed records of each incident: the date, time, location, who was present, exactly what was said or done, the harasser's name and position, and your response. Save emails, texts, or messages containing harassing language. Document how the harassment affected your work performance, mental health, or physical well-being. Take screenshots if harassment occurs online. Create a personal timeline and share it with a trusted friend or family member to establish that you reported it internally.

Step 2: Report Internally. Review your employer's sexual harassment policy and follow the reporting procedure. Most policies require reporting to HR or a designated complaint officer. Make your complaint in writing if possible—send an email summarizing the incidents and stating that you are formally complaining of sexual harassment. Request a written acknowledgment of receipt. Even if your employer does not have a formal policy, report the harassment to your supervisor or HR. Document what you reported, to whom, when, and any response. This step is important because it gives your employer a chance to investigate and stop the harassment, and it strengthens your legal claim later.

Step 3: File with the Illinois Department of Human Rights (IDHR). You have 300 days from the most recent act of harassment to file a Charge of Discrimination. You can file online at www2.illinois.gov/dhr, by mail at Illinois Department of Human Rights, James R. Thompson Center, 100 W. Randolph St., Suite 10-100, Chicago, IL 60601, or by phone at 312-814-6200 to request an intake appointment. You do not need an attorney to file. Provide your name, contact information, the respondent employer's name and address, dates of the harassment, a description of what happened, and the names of witnesses. The IDHR will assign an investigator.

Step 4: Investigation Process. The IDHR investigator will contact you and the employer. The investigation typically takes 60 to 180 days. The investigator will interview you, the alleged harasser, witnesses, and HR personnel. You may provide additional evidence and identify additional witnesses. Keep checking your case status online or via phone. The IDHR will issue a Determination of No Cause or a Finding of Substantial Evidence of discrimination. If substantial evidence is found, you may pursue a hearing before the Illinois Human Rights Commission or accept the finding and negotiate a settlement.

Step 5: Consult an Attorney. Before filing, consider consulting an employment law attorney experienced in sexual harassment cases in Illinois. An attorney can evaluate the strength of your claim, advise on potential damages, and represent you during investigation and any hearing. If you win, the employer may be ordered to pay your attorney fees and costs, so consult early. Most employment attorneys work on contingency (no upfront fee). If you cannot afford an attorney, contact the Illinois Lawyers' Referral Service (312-988-6018) or a local legal aid organization.
