How to Gather Evidence for a Wrongful Termination Case
If you were fired illegally in Pennsylvania or New Jersey, the strength of your case depends on the evidence you collect and preserve. Employers rarely admit to discriminatory or retaliatory motives — your employment lawyer builds the case through documentation, witness testimony, and circumstantial evidence that exposes the real reason behind your termination.
Evidence You Should Collect Immediately After Termination
Time is critical. Collect and preserve this evidence as soon as possible after being fired — ideally before you leave the building or within 24 hours.
Termination Documents
Save every document related to your firing: the termination letter or email, any written reason provided, final paycheck details, COBRA and benefits continuation notices, and any separation agreement or severance offer. If your employer provided a verbal explanation, write it down word-for-word while it is fresh in your memory, noting the date, time, and who was present.
Your Employment Records
Obtain copies of your complete personnel file — Pennsylvania law gives you the right to inspect your personnel file. Collect performance reviews from your entire tenure (especially recent positive reviews), disciplinary records, commendations and awards, job descriptions and offer letters, compensation history, and training records. A strong history of positive performance reviews followed by a sudden negative review shortly before termination is powerful evidence that the employer manufactured a pretext for firing you.
Communications Showing Discriminatory or Retaliatory Intent
Preserve emails, text messages, voicemails, Slack or Teams messages, and any written communications that reference your protected characteristic, complaints you made, leave you requested, or the decision to terminate you. Forward relevant emails to your personal account before you lose access to your work email. Take screenshots of messages on employer-controlled platforms.
Comparator Evidence
Identify employees who engaged in the same conduct your employer cited as the reason for your termination but were not fired. If you were terminated for “poor performance” but a similarly situated employee of a different race, gender, or age with comparable or worse performance was retained, that disparity is strong evidence of discrimination.
Timeline of Events
Create a detailed written timeline linking your protected activity (filing a complaint, requesting FMLA leave, reporting harassment) to the adverse actions that followed. Include dates, what happened, who was involved, and any witnesses. Temporal proximity — the closeness in time between your protected activity and termination — is one of the most persuasive forms of circumstantial evidence in wrongful termination cases.
Evidence Your Attorney Will Obtain Through Legal Channels
Once your attorney files a charge or lawsuit, formal discovery tools become available. Depositions allow your attorney to question decision-makers under oath. Document requests compel the employer to produce internal communications, investigation files, and HR records. Interrogatories require written answers to specific questions about the termination decision. Subpoenas can obtain records from third parties such as staffing agencies, payroll providers, and insurance companies.
Mistakes That Destroy Evidence
Do not delete any communications related to your employment — even messages that seem unfavorable. Do not return your work laptop or phone without copying personal files and relevant work communications. Do not post about your termination on social media. Do not record conversations without understanding your state’s consent laws (Pennsylvania requires all-party consent). Do not sign a severance agreement without legal review — it may contain provisions that limit your ability to use certain evidence.
