Digital personnel file & data model
HiBob
"Core HR system of record" with eSign and document management is claimed on the homepage, but the evidence says nothing about org structure, custom fields, or whether contract and salary history is kept effective-dated rather than overwritten. A personnel file without evidenced change history is something a Betriebsrat cannot audit, so this sits below the anchor that requires dated history on core employment fields.

The captured pages name a personnel-management module and the employee data it holds — tax data, demographic personal data, attendance and compensation information — with self-documenting audit trails and segregation of duties claimed. But we found no public information on document storage, an org chart, custom fields, or whether contract and salary changes keep dated history rather than overwriting it; without that history I cannot tell an employee what their file said a year ago, which is what a works council needs at a dismissal hearing.
