The one-sentence rule: Discovery is where both sides test whether the story can survive documents, sworn answers, and third-party evidence. The goal is not to hide the ball; it is to build the record.

The 60-Second Issue Map

Issue What to ask Risk / signal Employee focus
Preservation What texts, emails, files, photos, devices, calendars, and social media may be relevant? CRITICAL Do not delete, alter, or “clean up” after a dispute becomes foreseeable.
Document requests What records does each side demand? HIGH Relevance and proportionality still matter; objections must be strategic, not reflexive.
Interrogatories What facts, witnesses, damages, and contentions must be answered under oath? HIGH Accuracy and consistency matter.
Admissions Which propositions can be admitted, denied, or qualified? HIGH Careless responses can narrow or damage the case.
Third parties Former coworkers, medical providers, new employers, agencies, vendors? VARIES Subpoenas can expand the evidence beyond company files.

Five Rules That Matter

  1. Once litigation is reasonably anticipated, potentially relevant evidence should be preserved. Deleting or altering evidence can create sanctions and credibility problems.
  2. Written discovery typically includes document requests, interrogatories, and requests for admission, with different rules in state and federal court.
  3. Discovery responses are not casual emails. They can be verified under oath, used in depositions, attached to motions, and shown at trial.
  4. Employment cases commonly involve personnel records, internal communications, comparator evidence, policies, investigation files, payroll data, and electronic systems.
  5. Discovery is iterative. One email may identify a witness; one witness may identify a spreadsheet; one spreadsheet may turn an “opinion” dispute into arithmetic.

Discovery Is Documentary Cross-Examination

Preserve Request Test
Keep relevant evidence intact Ask for the documents the employer story predicts should exist Compare sworn answers to emails, policies, dates, and data

Documents / Actions To Save Now

  • Personal devices containing relevant communications
  • Emails / texts / messaging exports
  • Calendars and notes
  • Job-search records
  • Medical records relevant to claimed injury
  • Damages documents
  • Witness list
FROM THE EMPLOYER’S SIDE: large employers defend through systems. HRIS, email, payroll, CRM, access logs, performance databases, ticketing systems. Good discovery asks which system should contain the answer – then checks whether it does.
