How to back up work evidence without tipping off your employer

Most modern employers run data-loss-prevention (DLP) software that flags large file transfers, USB drives, and unusual cloud uploads. Here's how to preserve what you need without lighting up their dashboard.

Only preserve your own work product, communications you sent or received, and documents you legitimately had access to in your job. Taking confidential company files you have no business with can give the employer a fire-for-cause excuse and weaken your case.

The rule that matters: phone camera beats screenshot tools

The single most reliable, untraceable, court-friendly method of preservation is also the lowest-tech: photograph your work computer screen with your personal phone.

  • It doesn't go through company networks (no DLP alert).
  • It doesn't leave a USB log or "file copied" event.
  • Photos carry EXIF metadata (date/time/GPS) that proves when you captured something. That's authentication courts care about.
  • Original onboarding documents, write-ups, severance offers — photograph them flat on a desk before you sign or scan anything.
Don't: email work documents to your personal Gmail as bulk attachments, plug in a USB drive, or use Dropbox/Drive on your work laptop. All three trigger DLP. All three look bad if your employer ever investigates "what did this employee take."

What to preserve, in priority order

  1. The trigger event. The write-up, the email firing you, the schedule change — whatever started this. Photograph the original. If it was emailed, forward only that single email to your personal address.
  2. Your complaint(s). Whatever you sent (text, email, HR ticket) and any reply acknowledging receipt. These prove "protected activity" if it ever matters.
  3. Onboarding documents. Especially the offer letter, employee handbook, arbitration agreement, and any policies you allegedly violated. Original conditions matter; employers rewrite handbooks.
  4. Performance records BEFORE the trigger. Reviews, "good job" emails, awards, bonuses. Defends against the "she was always a low performer" rewrite.
  5. Pay records. Pay stubs, time records, schedule history. Especially if pay or hours changed after the complaint.
  6. Witness list. Names, departments, contact info (personal email if you have it) of anyone who saw what happened or could corroborate. Get this before you leave the company — afterward people get hard to reach.

What goes on what device

The cleanest separation that holds up in litigation:

  • Phone camera roll — original photos, with their auto-generated EXIF intact. Don't crop or filter; that strips metadata.
  • Personal cloud (iCloud, Google Photos, etc.) — automatic phone backup. Provides an additional timestamp from the cloud provider.
  • Personal email — forwarded emails from your work account that you were a sender or recipient on.
  • Receipts.law evidence vault — Fernet-encrypted server-side storage that organizes everything into 11 sections an attorney can navigate fast.
Recording phone calls and meetings: This is state-specific. Federal law and ~38 states allow one-party consent (you can record a call you're on). The other ~12 states require all-party consent (Pennsylvania, California, Florida, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, New Hampshire, Washington, Connecticut). Recording without consent where it's required can be a crime. Check your state's law before recording anything.

A note on company-issued laptops and phones

Assume everything you do on a company device is monitored. Many employers use endpoint software that captures keystrokes, screenshots, and clipboard. Personal logins (to your bank, your therapist, anything) made on a work device can show up in litigation discovery. If you're already in a retaliation situation, switch personal accounts to personal devices today.

Receipts.law auto-organizes everything you upload into 11 sections, hashes each file for chain-of-custody, and OCRs your screenshots so the AI can read them.
