Five Common Retaliation Claims Chicago Employers Face and How to Fight Them

 Posted on July 21, 2026 in Business Law

The Chicago regulatory environment is very favorable to employees. An employee does not have to win an original discrimination, harassment, or wage complaint to bring a retaliation claim. In many cases, the employee only needs to show that they engaged in legally protected activity and then suffered some type of punishment because of it.

This creates major risk for employers because a legitimate disciplinary decision must often occur shortly after an employee complains about something. Our Chicago business law attorney can help employers dealing with employment law issues. Whether you need to respond to employee complaints or defend against retaliation allegations before they become expensive lawsuits, we are here to help.

Five Common Types of Workplace Retaliation

Retaliation After a Discrimination or Harassment Complaint

Federal laws such as Title VII of the Civil Rights Act prohibit retaliation against employees who report or oppose discrimination based on race, color, religion, sex, or national origin. These protections also apply when employees participate in an Equal Employment Opportunity Commission investigation or another discrimination proceeding.

Illinois employers must also comply with the Illinois Human Rights Act. Under 775 ILCS 5/6-101, employers may not retaliate against someone who reports or opposes conduct that the person reasonably and in good faith believes violates the Act.

This means employers should take a complaint seriously even when it initially appears weak. Investigate it, prevent managers from reacting emotionally, and document any unrelated performance problems carefully.

Retaliation Against Someone Who Participates in an Investigation

Employees are protected not only when they make their own complaints, but also when they serve as witnesses, answer questions, or provide evidence during an investigation.

Any action by an employer (or manager) serious enough to discourage a reasonable employee from reporting misconduct or participating in an investigation may create legal problems.

Employers should remind everyone involved that witnesses cannot be punished for cooperating. When possible, someone who is not accused of wrongdoing should oversee later employment decisions involving the complainant and witnesses.

Retaliation After Wage or Overtime Complaints

Employees may claim retaliation after filing complaints about minimum wage, overtime, improper deductions, or unpaid work. These claims are often made after an employee:

• Asks why overtime was not paid

• Complains about working off the clock

• Questions whether an employee is properly classified

• Participates in a wage investigation

• Discusses pay practices with coworkers

An employer can still discipline an employee who made a wage complaint, but the decision should be based on a legitimate, well-documented reason. The employer should be able to show that the same rules have been applied consistently to other workers.

Retaliation for Requesting Protected Leave

The Family and Medical Leave Act prohibits covered employers from interfering with an employee’s protected leave rights or retaliating against someone for requesting or using FMLA leave. Examples include disciplining an employee for covered absences, denying a promotion because of leave use, or counting protected leave against an attendance record.

FMLA leave must be tracked separately from ordinary attendance violations. Any decision involving an employee who recently requested leave should be reviewed carefully. 

Retaliation Against a Whistleblower

Illinois employers may face claims from employees who report suspected legal violations, safety dangers, fraud, or other misconduct.

The Illinois Whistleblower Act, 740 ILCS 174, prohibits certain retaliatory actions against employees who disclose or threaten to disclose conduct they believe violates the law or creates a serious danger to workers or the public. It also protects employees who refuse to participate in conduct that would violate the law.

Employers should avoid immediately labeling a complaining employee as disloyal or difficult. The better approach is to investigate the report, preserve relevant records, and separate the complaint from any legitimate performance concerns.

How Can Chicago Employers Defend Against Retaliation Claims?

The strongest defense usually begins before a claim is filed. Employers should:

• Have clear complaint and anti-retaliation policies

• Train supervisors to recognize protected activity

• Investigate complaints promptly

• Document performance issues as they happen

• Apply workplace rules consistently

• Consult an attorney before firing or demoting someone who has recently complained 

An employee’s complaint does not create protection from all discipline. Employers may still make legitimate business decisions. The challenge is showing that the decision was based on lawful reasons rather than the employee’s protected activity.
