Workplace harassment under Illinois and federal law
Workplace harassment in Illinois is typically addressed under the Illinois Human Rights Act (IHRA), which prohibits offensive conduct that is severe or pervasive enough to create a hostile work environment or result in adverse employment decisions. Employers may be liable for harassment by supervisors, coworkers, or nonemployees in certain circumstances. Protected traits include those listed in the table above, and retaliation for reporting harassment is also unlawful.
Steps to address workplace harassment
- Review employer policies and any employee handbook.
- Document each incident with dates, times, locations, and witnesses.
- Report the harassment in writing to HR or a designated supervisor.
- Preserve evidence, such as emails, texts, and recordings where permitted by law.
- Consider filing a complaint with the Illinois Department of Human Rights (IDHR) or the Equal Employment Opportunity Commission (EEOC).
Cyberharassment and electronic conduct in Illinois
Illinois law explicitly criminalizes cyberharassment, which includes using electronic communications to harass another person without lawful purpose. Examples are sending threatening messages, impersonating someone online, or disseminating harmful content. Consequences can include criminal penalties and civil liability, including injunctive relief and damages. Minors are afforded additional protections under laws related to cyberbullying and electronic device harassment.
Practical steps if you are being cyberharassed
- Save all messages, screenshots, and metadata.
- Use platform reporting tools to request removal.
- Block the sender and limit sharing of personal information.
- Contact law enforcement if threats, extortion, or doxxing are involved.
- Consult a civil attorney for potential injunctive or monetary remedies.
How to file a harassment complaint in Illinois
Filing options depend on the context. For employment and housing discrimination, the Illinois Department of Human Rights (IDHR) accepts complaints and may investigate or issue a right to sue letter. The Equal Employment Opportunity Commission (EEOC) handles federal claims. For criminal harassment, contact local law enforcement. Court filings may be pursued for civil remedies, such as injunctions or damages, depending on the circumstances.
Important deadlines to keep in mind
- IDHR complaints generally must be filed within 180 days of the alleged harassment.
- Federal EEOC filings must occur within 180 or 300 days, depending on state processing agreements.
- Civil lawsuits for harassment or related torts are typically subject to a two year statute of limitations in Illinois, though specific deadlines vary by claim type.
Remedies, enforcement, and common outcomes
Enforcement of Illinois harassment law can result in a range of remedies. These may include restraining orders, back pay, compensatory damages, punitive damages in certain cases, policy changes, and training. Outcomes depend on evidence, jurisdiction, and whether the matter proceeds administratively or through litigation. Some cases are resolved through settlements, while others advance to hearings or court decisions.
