What counts as evidence in a wrongful termination case?

Anything that shows what happened, when it happened, and who knew — emails, texts, Slack/Teams messages, performance reviews, HR correspondence, calendar invites, screenshots, voice notes, and witness names. Contemporaneous notes you wrote at the time carry more weight than notes reconstructed later.

How soon should I start documenting?

The moment something feels wrong — before you are terminated, not after. Most cases collapse in the 6–18 month 'Intake Dead Zone' because evidence was gathered too late, from memory, after access to systems was revoked.

Can I record conversations at work?

It depends on your state. Roughly 38 U.S. states are one-party consent (you can record a conversation you are part of); the rest require all-party consent. Check your state before recording, and never record where you have no legal right to be.

What is a chain of custody and why does it matter?

Chain of custody is a verifiable record that a file has not been altered since it was captured. A SHA-256 hash plus a trusted timestamp lets an attorney or agency confirm authenticity — which is why Oritura hashes every upload at intake.

How long do I have to file a claim?

Federal EEOC charges are typically 180 days from the adverse action (300 days in states with a deferral agency). State agencies, FLSA wage claims, and contract claims each run on their own clocks. Document now; decide later.

Wrongful termination evidence:
what to save, and when.

Most wrongful termination cases are not won or lost in a courtroom. They are decided in the six to eighteen months before an attorney is ever retained — by whether the evidence exists, and whether anyone can prove it has not been altered.

Why evidence decides the case

Employment law is a burden-shifting system. Under the McDonnell Douglas framework, you establish a prima facie case; the employer offers a legitimate reason; you show that reason is pretext. Every one of those steps is an evidence question, not a memory question.

Reviews written after the fact, screenshots taken years later, and reconstructed timelines are routinely challenged and often excluded. Contemporaneous, timestamped, hash-verified records are not.

What to save

Preserve anything that documents what was said, decided, or observed.

Communications

Emails to and from managers, HR, and peers — including replies and full headers.
Slack, Teams, and internal chat threads (export before you lose access).
Text messages, including delivery timestamps and phone numbers.
Voicemails, meeting recordings you were lawfully part of, and calendar invites.

HR and personnel

Offer letter, handbook, and every version of your job description.
Performance reviews, PIPs, and any written warnings — signed and unsigned.
Complaint filings, investigation notices, and outcome letters.
Pay stubs, bonus letters, and benefits changes around the adverse action.

Context

Names and titles of witnesses — even if they will not speak now.
Org charts, seating charts, and shift schedules that show who was where.
Public statements from leadership referencing the policy, restructure, or reason cited.

How to preserve it

Capture originals, not descriptions. A screenshot of an email header beats a paraphrase of what it said.
Save outside the employer's systems. Personal email, personal cloud, or an encrypted vault. Corporate devices can be wiped the day of termination.
Timestamp and hash. A SHA-256 hash plus a trusted timestamp proves the file existed on a given date and has not been modified. Oritura hashes every upload at intake and returns a Bates number.
Write contemporaneous notes. Same day when possible. Facts, times, who was present. Not conclusions.
Know your recording law. One-party vs. all-party consent varies by state and by call type.

Build a timeline

A timeline is the single most useful artifact you can hand an attorney. It converts a pile of documents into a story with dates. For each event, capture:

Date and time (with time zone if remote).
What happened, in one sentence.
Who was involved and who witnessed it.
The evidence item that proves it (link, hash, or filename).

Temporal proximity — an adverse action shortly after a protected activity — is one of the strongest circumstantial signals in a retaliation claim. It only works if the dates are exact.

Mistakes that quietly kill claims

Forwarding company email to personal accounts in violation of policy.
Downloading confidential files that were not yours to take.
Recording in an all-party-consent state without consent.
Posting about the situation publicly on social media before filing.
Signing a severance release without reading the ADEA 21/7-day windows.
Waiting to consult an attorney until after the 180/300-day EEOC clock has run.

Deadlines to know

EEOC charge: 180 days from the adverse action (300 days in deferral-agency states).
State agency (e.g. MDHR, DFEH): varies — often 300 days to 1 year.
FLSA wage claims: 2 years, or 3 for willful violations.
Section 1981 race discrimination: up to 4 years.
Contract and defamation: state-specific, typically 1–6 years.

Deadlines are jurisdiction-specific. Confirm with a licensed attorney in your state.
