I hate billiable hours

The billable hour requirement at my firm causes me much stress. Especially since I don't have much work to do right now. I still have to find about 3 hours of work to bill for yesterday in addition to the 8 plus hours I need for today. And don't even get me started about tomorrow. Maybe I will call in sick since I will be sick after sitting here all day with nothing to do and worrying about it. But then that may look suspicious since the next day is July 4. Shit. This office is such crap. I hate it here.
