Keep personal details, contract terms and supporting documents together. The employee record can hold an address, profile picture and documents for personal, managerial, qualification, leave and duty purposes.
The most sensitive fields, a fiscal number, an ID or passport number, a home address, a phone number, are held apart from general viewing. They are returned only through a separately gated endpoint that requires write-level access to the employee's primary unit, not the broader read tier that lets a wider set of roles see general employee and roster information. Viewing your own confidential fields through self-service needs only individual-level access, nothing more.
