@Jim When searching for Co-workers in the search bar at the top, you will be able to set the filter to Archived(next to the Co-workers button) which will display the Co-workers that have been archived with the search parameters used - Please see screenshot:
For the requests list it appears that there is no filter option that applies to users with status, only the status of the request/incident but it does appear that if an Archived user is the Owner of a Request/Incident then the Request still shows in the main list view with them being presented as the owner.
