Digital personnel file & data model
HiBob
Nothing here proves history is kept rather than overwritten.
Workday HCM
The captured pages list HCM modules and an AI-driven self-service for managing "HR data", but we found no public information on the personnel file itself — no document types or e-signature, no org chart, no custom fields, no effective-dated history. The audit-trail claims I did find sit on the financial-management pages, not on anything describing an employee record.
