Dealing with ticket history of contact who left company

Dealing with ticket history of contact who left company

Are there any best practices for handling the ticket history of a contact who is no longer with the account? I would like to delete the contact but retain the tickets in the account. One thought I had was to create a fake contact under the account called "Former Employee" or something and merging each person who left with that contact. Over time Former Employee would basically become a dumping ground for all tickets from people who had left. Any other suggestions?
