employment.hard_deleted

This event is triggered when an employment is permanently erased from Remote, and means the
record is physically gone: a subsequent GET /employments/{id} returns 404 and the identifier
must not be queried again.

An employment that is hard deleted has often already been soft deleted, which triggered
employment.onboarding.cancelled. You may therefore receive employment.onboarding.cancelled
first and this event weeks later.

This event may be delivered more than once, so it is safe to process repeatedly.
