New rule for 2006

Any evening where I get five hours of sleep or less will be followed by at least half a sick day.  Much like an illness, such a lack of sleep leaves me sore and achey, unable to concentrate, and very angry.  Anger, like illness, should not be spread to your co-workers.

This is generally reserved for times when you just can't get to sleep (like last night, when I got 4 hours of uninterrupted sleep). If you deliberately stay up all night, I'd say you have to take your lumps, but that still doesn't help anybody. Take the bloody day off. The world isn't going to end, and if you're that important you can probably work from home anyway. You lucky stiff.
