...You're moaning about not having enough work to do? 
This is why I always have a book with me. 
I work an IT job (software tester) where I have to log every hour I spend at work in a software system and categorize the time. My time is assigned to specific projects or to specific fixes, or gets dumped into a couple of generic categories. (It has to add up to at least 40 hours in a week.) So, yeah, if I consistently don't have enough projects or fixes to work on, it looks bad, 'cause every minute gets tracked. Not to mention, if there's not enough work to do over a long enough period of time, I or someone else in my department could theoretically lose his or her job. In practice, it's not likely to happen, especially not to me, but we have had layoffs in my company in the past.
I'm also one of those people who is
really efficient, fast, and knowledgeable at what I do (that's what 12 years of experience gets me), and I'm accustomed to having a workload at least 2 to 3 times what other people in my group normally handle. So I get really bored when the workload is light.
I always have a book to read, too, but that's for lunch breaks; even if I don't have enough to do, the unspoken rule is that we should generally at least
look like we're busy.
