Everyone focuses on security tasks, after you fire the idiot, such as changing passwords, but that's just one part of the To Do list. More important, in the long run, is the cleanup job that needs to be done after you fire the turkey, looking for the hidden messes and security flaws the ex-employee may have left behind. Otherwise, you’ll still be cleaning up the problems six months later, when you discovered that the backup he automated... well, not that we are speaking from experience or anything, but we wanted to bring him back in just so we could fire his butt all over again. Rick Cook has a checklist of Stuff To Look For in his article, Cleaning Out The Turkey Coop: What To Do After You Get Rid of an Incompetent Employee. See what you might add to the list."
