I'm on a first name basis with our IT guys. While I'm not entirely sure that's a good thing, I have worked for companies who have Maximized Shareholder Value by outsourcing IT services to a third party.
This is most assuredly NOT a Good Thing. Aside from the fact that you end up dealing with jobsworths who try to avoid doing anything, you're much less likely to be on a first (or any) name basis with the folks at the other end of the phone...and so, much more susceptible to this kind of attack.
