Five Warning Signs That Your Termination May Have Been Illegal in Illinois

How to Recognize Wrongful Termination, Workplace Discrimination, Retaliation, and Other Violations of Illinois Employment Law

By Attorney Danielle A. Pinkston | Pinkston Law Group, P.C.

Imagine arriving at work on a Monday morning expecting another ordinary day.

Instead, your supervisor asks you to report to Human Resources.

You sit down, and within minutes, you are informed that your employment has been terminated.

You are shocked.

Perhaps you recently complained about discrimination, requested medical leave, reported workplace misconduct, or questioned why you were being treated differently from your coworkers.

Maybe your employer claims your termination was based on poor performance, even though you previously received positive evaluations.

Or perhaps you were fired without any explanation at all.

Was your termination unfair, or was it actually illegal?

The distinction matters.

Illinois generally follows the at-will employment doctrine, which means employers ordinarily may terminate employees for lawful reasons or without providing a reason.

However, at-will employment does not give employers unlimited authority to fire employees.

Federal and Illinois laws prohibit certain discriminatory and retaliatory terminations. Employment contracts and other legal protections may also restrict an employer’s right to terminate employment.

Here are five warning signs that your termination may have violated Illinois or federal employment law.

1. Warning Sign One: You Were Fired Shortly After Reporting Discrimination or Harassment

One of the most significant warning signs of potentially unlawful termination is being fired shortly after making a legally protected workplace complaint.

Federal and Illinois employment laws prohibit certain forms of retaliation against employees who oppose unlawful discrimination or participate in protected proceedings.

For example, Title VII of the Civil Rights Act of 1964 prohibits retaliation against employees who engage in activity protected by that statute.

The Illinois Human Rights Act also provides retaliation protections.

Example: Reporting Racial Discrimination

Imagine you are a Black professional working in a corporate office.

You notice that employees of another race receive promotions and favorable assignments while equally qualified Black employees are repeatedly overlooked.

You report your concerns to Human Resources.

Two weeks later, your supervisor begins criticizing your performance.

You receive a written warning despite having no prior disciplinary history.

Shortly afterward, your employment is terminated.

Could that be retaliation?

Potentially.

The timing, your employer’s knowledge of the complaint, and changes in your treatment may be relevant evidence.

However, temporal proximity alone does not automatically establish unlawful retaliation.

An employee generally must demonstrate that the activity was legally protected and that the challenged employment action was connected to it under the applicable legal standard.

What Evidence Should You Preserve?

Relevant evidence may include:

• Your written complaint to Human Resources.
• Emails or messages acknowledging the complaint.
• Performance evaluations before and after the complaint.
• Disciplinary notices.
• Statements by supervisors.
• Information about similarly situated employees.

Important: Not every workplace complaint is protected by every anti-retaliation law. The nature of the complaint matters.

2. Warning Sign Two: You Were Fired After Requesting Medical Leave or a Disability Accommodation

Another warning sign is termination shortly after requesting protected medical leave or a reasonable accommodation.

The Family and Medical Leave Act (FMLA) generally provides eligible employees of covered employers with up to 12 workweeks of unpaid, job-protected leave for qualifying reasons.

The Americans with Disabilities Act (ADA) prohibits certain disability discrimination and requires reasonable accommodation for qualified employees, absent undue hardship.

The Illinois Human Rights Act also provides disability-related employment protections.

Example: Terminated After Surgery

Imagine you undergo surgery and need six weeks to recover.

You notify your employer, submit medical documentation, and receive approval for FMLA leave.

While you are recovering, your supervisor complains about the inconvenience of your absence.

Two weeks later, you receive a termination letter.

Was that termination illegal?

It may have been, depending on the facts.

An employer generally cannot lawfully terminate an employee because the employee exercised protected FMLA rights.

Likewise, an employer cannot lawfully retaliate against an employee for requesting an accommodation protected by the ADA.

However, medical leave does not create absolute protection against termination.

For example, a genuine company-wide reduction in force may affect an employee on leave if the employee would have been terminated regardless of the leave.

What if Your FMLA Leave Has Expired?

Employees sometimes believe that once FMLA leave expires, employers may automatically terminate them.

That is not necessarily correct.

An employee with a qualifying disability may be entitled to consideration of additional finite leave as a reasonable accommodation under the ADA.

However, the ADA does not automatically require indefinite leave or accommodations that impose an undue hardship.

The circumstances must be evaluated individually.

3. Warning Sign Three: Your Employer Suddenly Claims You Have Performance Problems

A sudden change in an employer’s explanation of an employee’s performance may be a warning sign of unlawful termination.

For example, imagine receiving positive evaluations for several years.

You meet your performance goals, receive bonuses, and are repeatedly praised by management.

Then you report workplace discrimination or request a protected accommodation.

Almost immediately, your supervisor begins documenting alleged performance problems.

You receive disciplinary warnings and are eventually terminated.

Could your employer’s explanation be a pretext for discrimination or retaliation?

Potentially.

What Is Pretext?

In employment discrimination and retaliation cases, pretext refers to an employer’s stated explanation that may conceal the actual unlawful reason for an employment decision.

Relevant evidence may include:

• Positive performance evaluations before protected activity.
• Sudden disciplinary action after a complaint or leave request.
• Inconsistent explanations for termination.
• Failure to follow established disciplinary procedures.
• Evidence that similarly situated employees were treated differently.
• Statements suggesting discriminatory or retaliatory motivation.
• However, an employer’s poor judgment, unfair decision, or mistaken assessment does not automatically establish unlawful discrimination.

The evidence must support the elements of a legally recognized claim.

Example: False Accusations of Misconduct

Suppose an employee reports sexual harassment.

A month later, the employer accuses the employee of insubordination.

The employer refuses to consider evidence contradicting the accusation and terminates the employee.

If the allegation was manufactured to punish the employee for protected activity, it may be evidence of unlawful retaliation.

The employee should preserve the accusation, any written response, and relevant supporting documents.

4. Warning Sign Four: You Were Treated Differently Because of a Protected Characteristic

Federal and Illinois employment laws prohibit certain employment discrimination based on legally protected characteristics.

Depending on the applicable law, these characteristics may include:

• Race.
• Color.
• Religion.
• Sex.
• Pregnancy and related conditions.
• National origin.
• Disability.
• Age, when applicable statutory requirements are met.
• Other characteristics protected by Illinois law.

The Illinois Human Rights Act includes additional protections beyond some federal statutes.

Example: Unequal Discipline

Imagine two employees commit comparable workplace policy violations.

One employee is Black, and the other is white.

The Black employee is terminated immediately.

The white employee receives a warning.

Could this be evidence of racial discrimination?

Yes, depending on the circumstances.

However, the employees must be sufficiently comparable in relevant respects.

An employer may point to legitimate differences involving job responsibilities, disciplinary history, decision-makers, or the seriousness of the conduct.

What if Your Employer Makes Discriminatory Comments?

Statements by supervisors or decision-makers may be relevant evidence.

For example, age-related comments accompanying a decision to replace an older employee with a younger employee may warrant further examination.

Similarly, racially discriminatory statements, comments about pregnancy, or hostility toward disability accommodations may be relevant.

The significance of such statements depends on their context and relationship to the employment decision.

An employer cannot avoid discrimination laws simply by labeling a discriminatory termination a business decision.

5. Warning Sign Five: You Were Fired After Reporting Illegal Conduct or Exercising a Protected Legal Right

Employees may have legal protections when reporting certain unlawful conduct or exercising specific statutory rights.

For example, depending on the circumstances, protections may arise under:

• The Illinois Whistleblower Act.
• The Illinois Workers’ Compensation Act.
• The Occupational Safety and Health Act.
• Federal and Illinois wage laws.
• Illinois common-law retaliatory discharge principles.
• Example: Filing a Workers’ Compensation Claim

Imagine you suffer an injury while working in a warehouse.

You report the injury, obtain medical treatment, and pursue workers’ compensation benefits.

Your supervisor becomes upset and tells you that filing the claim will cause problems for the company.

Shortly afterward, you are terminated.

Illinois law prohibits certain retaliation against employees for exercising workers’ compensation rights.

Under qualifying circumstances, the employee may have a common-law retaliatory discharge claim.

Example: Reporting Workplace Safety Violations

Suppose an employee reports serious workplace safety concerns to the appropriate government agency.

The employer learns about the report and fires the employee.

Depending on the facts, federal or Illinois whistleblower protections may apply.

However, these claims have different legal requirements and filing deadlines.

For example, complaints alleging retaliation under Section 11(c) of the federal Occupational Safety and Health Act generally must be filed with OSHA within 30 days.

Employees should not assume that all whistleblower claims have the same deadline.

6. Does Illinois Require Employers to Give a Reason for Termination?

Generally, Illinois at-will employers are not required to provide a detailed explanation for every termination.

However, an employer’s refusal to provide a reason does not establish that the termination was lawful.

Likewise, an employer’s decision to provide a reason does not automatically establish that the explanation was truthful.

The relevant question is whether the termination violated an applicable legal protection.

An employment attorney may examine the employer’s explanation alongside other evidence.

7. Can You Sue if Your Employer Fired You Based on False Accusations?

Potentially, but false accusations alone do not automatically establish wrongful termination.

Illinois employers may sometimes lawfully terminate at-will employees based on mistaken information.

However, fabricated accusations may support a legal claim when they are used to conceal unlawful discrimination, retaliation, or another prohibited reason.

In some circumstances, false statements published to third parties may also raise separate defamation issues.

The legal analysis depends on the specific facts and applicable law.

8. What if Your Employer Offers You Severance After Firing You?

A severance agreement may provide financial assistance following termination.

However, it may also require you to release existing legal claims.

Before signing, employees should review:

• The severance amount.
• The scope of the release.
• Confidentiality and nondisparagement provisions.
• Noncompete or nonsolicitation restrictions.
• Health insurance benefits.
• Employment reference provisions.
• Applicable signing and revocation deadlines.

Employees age 40 or older may have additional protections when asked to waive federal age discrimination claims.

A severance offer does not automatically establish wrongdoing by the employer.

However, employees should understand their potential legal rights before signing a release.

9. What Damages Can You Recover in an Illinois Wrongful Termination Lawsuit?

Available remedies depend on the legal claims established.

Potential relief may include:

Back Pay: Lost wages and benefits resulting from unlawful termination.

Front Pay: Compensation for certain future lost earnings when authorized.

Reinstatement: Returning the employee to employment where appropriate.

Emotional Distress Damages: Available under certain discrimination and retaliation laws.

Punitive Damages: Potentially available under qualifying claims when the applicable legal standard is met.

Attorney’s Fees and Costs: Recoverable where authorized by statute or another applicable legal basis.

Not every form of compensation is available under every claim.

For example, the FMLA generally does not authorize emotional distress or punitive damages.

10. How Long Do You Have to File a Wrongful Termination Claim in Illinois?

Filing deadlines depend on the underlying legal claim.

Federal Discrimination and Retaliation: Many Illinois employees must file an EEOC charge within 300 days of the challenged employment action.

Illinois Human Rights Act: For many violations occurring on or after January 1, 2025, the general administrative charge filing period is two years, subject to applicable exceptions.

FMLA: Generally two years, or three years for willful violations.

Federal OSHA Retaliation: Generally 30 days under Section 11(c).

Illinois Common-Law Retaliatory Discharge: Generally five years, although certain defendants and circumstances may involve shorter periods.

Employees should not assume that filing an internal complaint, requesting reconsideration, or negotiating severance extends these deadlines.

11. What Should You Do if You Believe Your Termination Was Illegal?

If you believe your employer violated your rights, consider these steps:

1. Preserve your termination letter and the employer’s stated reason.

2. Document the events leading up to termination.

3. Keep copies of relevant complaints, leave requests, and accommodation requests.

4. Preserve performance evaluations and disciplinary records you are legally authorized to possess.

5. Identify witnesses who may have relevant information.

6. Document lost wages, benefits, and job-search efforts.

7. Review any severance agreement before signing.

8. Consult an Illinois employment attorney promptly.

Avoid deleting relevant evidence or improperly accessing confidential employer systems.

12. The Bottom Line: Five Warning Signs Your Termination May Have Been Illegal

The five warning signs are:

1. You were fired shortly after reporting discrimination or harassment.

2. You were terminated after requesting protected medical leave or a disability accommodation.

3. Your employer suddenly claimed you had performance problems.

4. You were treated differently because of a legally protected characteristic.

5. You were fired after reporting certain illegal conduct or exercising a protected legal right.

These circumstances do not automatically prove wrongful termination. However, they may warrant further legal investigation.

Illinois employees have important rights, even in an at-will employment state.

Understanding those rights may help you determine whether your termination was simply unfair or legally actionable.
