What Evidence Do I Need for an EEOC Complaint?

Building a strong EEOC case requires evidence that supports your claims. While you don't need to prove your case beyond doubt to file, having good documentation strengthens your complaint and helps investigators understand what happened.

Don't let lack of perfect evidence stop you. The EEOC can subpoena records you don't have access to. Document what you can, and let the investigation do its work.

What the EEOC Needs to See

To investigate your charge, the EEOC looks for evidence that:

• You have a disability or medical condition
• You requested accommodation or your employer knew of your need
• Your employer denied accommodation, discriminated, or retaliated
• The employer's actions were connected to your disability
• You don't need to prove all of this yourself, you need to provide enough for the EEOC to investigate.

Types of Evidence

Written Records

The most valuable evidence is often what's in writing:

Emails and texts about your accommodation request, your disability, or treatment at work

Letters and memos documenting formal correspondence about your request, denial, or any disciplinary actions

Your written accommodation request, especially valuable if you put it in writing

Written responses from your employer, including denials and reasons given

Keep copies of everything. If communications were verbal, document them immediately in writing.

Medical Documentation

Medical records support your disability and need for accommodation:

• Diagnosis or documentation of your condition
• Healthcare provider statements about limitations
• Recommended accommodations from medical professionals
• You don't necessarily need to provide detailed medical records, often a letter from your provider describing your limitations and needed accommodations is sufficient.

Employment Records

Documents showing your employment history and treatment:

• Performance reviews (especially those before and after your request)
• Disciplinary records
• Job descriptions
• Attendance records
• Awards, commendations, positive feedback

Witness Information

People who observed what happened:

• Coworkers who witnessed discrimination or retaliation(definition available)
• People you told about events at the time
• Anyone who can corroborate your account

You don't need written statements from witnesses to file, just their names and contact information. The EEOC can interview them.

Comparative Evidence

Information showing you were treated differently:

• How similarly situated employees without disabilities were treated
• Whether others received accommodations you were denied
• Patterns in how your employer handles accommodation requests

Gathering Evidence

What you probably have

Start with what you already possess:

• Emails in your personal account (forward work emails to personal before they're deleted)
• Text messages
• Your own notes and calendar
• Personal copies of documents you received
• Photos of relevant items or situations

What you might be able to get

Before leaving employment (or while still employed):

• Request copies of your personnel file (many states require employers to provide this)
• Keep copies of your own work product and communications
• Document policies that are relevant to your situation

What the EEOC can obtain

During investigation, the EEOC can request records from your employer:

• Personnel files and employment records
• Policies and procedures
• Internal communications about your request
• Records about how others were treated
• If your evidence is limited, the EEOC's ability to obtain employer records becomes important.

Documentation Best Practices

Keep a contemporaneous log

Document incidents as they happen:

• Date and time
• What happened
• Who was present
• What was said (as close to verbatim as possible)
• How it affected you
• Contemporaneous notes, records made at the time events occurred, carry more weight than memories reconstructed later.

Preserve electronic communications

• Forward relevant work emails to your personal account
• Screenshot important messages
• Save voicemails
• Back up digital files

Follow up verbal conversations in writing

After important conversations, send an email summarizing what was discussed:

"Per our conversation today, I understand that my accommodation request for [X] has been denied because [Y]. Please let me know if I've misunderstood anything."

This creates a written record and gives your employer a chance to correct any misunderstanding.

Be careful about employer property

Know your company's policies about taking documents. Generally:

• You can keep things you legitimately received
• Don't take documents you weren't supposed to have access to
• Don't take documents containing other employees' private information (unless directly relevant)
• Understand policies about copying or forwarding emails

Recording conversations

Laws about recording conversations vary by state. Some states allow recording with one party's consent (yours); others require all parties to consent. Research your state's rules before recording.

What If You Don't Have Much?

Limited documentation doesn't mean you shouldn't file:

• The EEOC investigates. They can request records you don't have.
• Your account matters. Your detailed, consistent description of events is evidence.
• Witnesses can corroborate. People who observed what happened or whom you told at the time support your account.
• Circumstantial evidence counts. Timing (a sudden change after your request) and patterns can demonstrate discrimination.

If your evidence is limited:

• Write a detailed narrative documenting everything you remember while it's fresh
• Identify potential witnesses
• Note inconsistencies in your employer's stated reasons
• Document the timeline carefully

What Not to Do

Don't fabricate evidence. False evidence destroys credibility and can have legal consequences.

Don't embellish. Stick to facts. Exaggeration undermines your case.

Don't destroy evidence. Preserve everything, even things that seem unfavorable.

Don't pressure witnesses. You can identify them, but don't coach them or pressure them to support your story.

What This Means for You

The best time to gather evidence is before and during the events, not after. If you're considering filing, start documenting now. Keep records of everything related to your accommodation request and treatment at work.

If you're gathering evidence after the fact, document what you remember, identify what documentation you can still obtain, and note who might serve as witnesses.

Remember: you're not a prosecutor building an airtight case. You're an employee reporting discrimination to the agency responsible for investigating it. Provide what you have; let the EEOC do its job.
