Documenting Evidence For An Illinois Wrongful Termination Claim

February 4 , 2025

Wrongful termination can have a profound impact on your professional and personal life. Losing your job without cause can lead to financial hardship, emotional distress, and damage to your reputation. If you believe you were wrongfully terminated in Illinois, it is crucial to gather evidence to support your claim. Proper documentation can strengthen your case and improve your chances of achieving justice. Our firm understands the complexities of both federal and Illinois employment laws, and we work closely with clients to ensure they have the evidence needed to protect their rights. 

What Is Wrongful Termination Under Illinois And Federal Law?

Wrongful termination occurs when an employer unlawfully fires an employee in violation of employment laws or a legally binding agreement. Illinois is an at-will employment state, which means employers can terminate employees for almost any reason as long as it does not violate laws or contracts. However, terminations based on discrimination, retaliation, or breaches of contract are illegal.

Under federal law, Title VII of the Civil Rights Act of 1964 (42 U.S.C. §2000e) prohibits termination based on race, color, religion, sex, or national origin. The Americans with Disabilities Act (ADA) and the Age Discrimination in Employment Act (ADEA) further protect employees from wrongful termination based on disability or age. In Illinois, the Illinois Human Rights Act (775 ILCS 5/) offers additional protections against discrimination and retaliation.

Types Of Evidence To Document For A Wrongful Termination Claim

Gathering evidence is a critical part of building a wrongful termination case. We advise clients to document all relevant information carefully and thoroughly. Types of evidence include:

  • Employment Contracts And Agreements – Review all written agreements, including offer letters, employment contracts, and non-compete agreements. These documents can clarify whether your termination violated specific terms of employment.
  • Personnel Files – Request a copy of your personnel file under the Illinois Personnel Record Review Act (820 ILCS 40/). It may contain performance reviews, disciplinary actions, and other employment records relevant to your case.
  • Company Policies And Handbooks – Company policies regarding termination, discipline, and reporting procedures can demonstrate whether your termination was handled consistently with established policies.
  • Communication Records – Preserve all emails, text messages, memos, and written correspondence between you and your employer. These records may reveal statements or patterns of behavior that support your claim.

Documenting Discrimination Or Retaliation Claims

If your claim involves discrimination or retaliation, documentation becomes even more essential. Illinois law and federal statutes prohibit firing employees based on protected characteristics or in retaliation for reporting misconduct.

  • Incidents Of Discrimination – Keep a detailed journal documenting specific instances of discrimination, including dates, times, locations, and witnesses.
  • Performance Reviews – Compare your performance evaluations before and after any reported discrimination or protected activity. Sudden negative reviews can be a sign of retaliation.
  • Witness Statements – Collect statements from coworkers who may have observed discriminatory behavior or retaliation against you.

Steps To Take After A Wrongful Termination

We encourage individuals who suspect wrongful termination to take the following steps immediately:

  1. Request A Termination Letter – Ask your employer for a written explanation of your termination.
  2. Preserve All Documents – Secure copies of all emails, contracts, and performance records.
  3. File A Complaint – Depending on the nature of your claim, you may need to file a charge with the U.S. Equal Employment Opportunity Commission (EEOC) or the Illinois Department of Human Rights (IDHR).
  4. Consult With An Attorney – Seek legal counsel to evaluate your case and determine the next steps.

Statute Of Limitations For Wrongful Termination Claims In Illinois

Timeliness is crucial when filing a wrongful termination claim. Under federal law, the EEOC generally requires claims to be filed within 180 days of the discriminatory act. However, in Illinois, this deadline may be extended to 300 days under the Illinois Human Rights Act.

FAQs About Documenting Evidence For A Wrongful Termination Claim In Illinois

What Should I Do If My Employer Refuses To Provide My Personnel File?

Under the Illinois Personnel Record Review Act (820 ILCS 40/), you have the right to access your personnel file. If your employer refuses, you may file a complaint with the Illinois Department of Labor to enforce your rights.

How Important Are Emails And Text Messages In A Wrongful Termination Claim?

Emails and text messages can serve as key evidence, especially if they contain discriminatory statements, sudden performance criticisms, or termination-related discussions. Preserving these communications can significantly strengthen your case.

Can I Still Pursue A Claim If I Was Terminated Without A Written Contract?

Yes. Illinois follows at-will employment laws, but wrongful termination claims can still be valid if the termination violates federal laws, such as Title VII, or if it involves retaliation, discrimination, or implied agreements.

How Can I Prove Retaliation If My Employer Denies It?

Retaliation can be demonstrated through circumstantial evidence, such as a sudden negative shift in performance reviews, reassignment to undesirable tasks, or termination shortly after filing a complaint.

What If My Employer Claims Poor Performance As The Reason For My Termination?

We can help you gather evidence, such as positive performance reviews, promotions, or awards, to challenge the employer’s claim and show that the termination was pretextual.
