Watching porn at work is a federal government tradition. Federal employees from agencies like the EPA, SEC, and FCC have been caught watching porn enough times, a Congressional rep actually thought a new law was needed to stop it. The bill was redundant. All federal agencies forbid the use of work computers to watch porn but that hasn't stopped these stories from surfacing with disturbing frequency.

At a certain point, porn-watching at work endangers a person's job. At other points before that, it endangers the employer itself. Zack Whittaker of TechCrunch dug up a Dept. of the Interior Inspector General's report [PDF] indicating a porn-watching employee inadvertently tried to the take the agency down from the inside.
