Document Record still remains for Pending Worker when Work Relationship is Canceled

Content (please ensure you mask any confidential information):

Today we build pre-onboarding journeys for pending workers, requires pending worker to complete the tasks, upload the certification/documents and so on, and then save the uploaded documents to the Document Record. What we found that is when we cancel the work relationship for pending worker, some data are gone including personal details, assignment, salary and so on. But Document Record still remains, which is not what are expecting.

Is this how system is designed or any options we have can control that and delete the Document Record automatically?
