When does an existing worker number get reused for a new work relationship?

The correct answer focuses on the principle of worker identification in Oracle HCM Cloud. An existing worker number is reused for a new work relationship when the new relationship is of the same type as the previous one. This means that if the new work relationship aligns with the original classification (for example, both are full-time employment positions), the system recognizes that this individual is continuing their engagement under the same category, allowing for continuity in tracking their employment history, benefits, and other relevant factors.

This reuse of worker numbers helps in maintaining a streamlined and organized database, ensuring clarity in the worker's records and avoiding duplication. By reusing the worker number, the system can consolidate their employment records effectively, which is beneficial for reporting and compliance purposes.

The other options do not apply because they involve either a change in the type of work relationship or the employer, which typically necessitates a new worker number to distinctly capture the nature of the employment change or the differing regulatory requirements associated with different employment types or legal employers.
