My company (Score 1)

At the Fortune 500 company that I work at, we have an intranet that is dwarfed only by the DoD. The majority of employees have access to pretty confidential business info. Anyone that has access to the network instantly has their privileges removed, their badge is deactivated, they are removed from the company directory and escorted to the door. This is for any employee that quits or is let go. Of course they will still give severance in most situations, but they try to limit their liability as much as possible.
