Evidence preservation is critical once an employer becomes aware of potential legal claims.

Best practices include:

  • Issuing a litigation hold to prevent deletion of relevant documents
  • Preserving emails, text messages, internal messaging platform communications, and electronic records
  • Securing personnel files, payroll records, timekeeping data, and policy acknowledgments
  • Preserving surveillance footage if applicable
  • Electronic data should not be altered or selectively deleted

Failure to preserve relevant evidence can result in court sanctions, adverse inference instructions to a jury, or increased settlement pressure.

In California employment disputes, spoliation of evidence often becomes a separate and significant issue.
