Anecdotally, when I was IT student sysadmin at a major university, I don't recall ever seeing admin staff doing actual work. Often times, you'd walk through the hallways and see rows and rows of offices of people screwing around on the Internet, or even playing video games. A good part of our job in IT itself was super slow as well except for the first two weeks of every semester, so we weren't much better. My boss would play WoW on the clock.
