It is time for my leave yet?

My department was already short staffed and then someone was fired yesterday. I work in the most un-organized, ridiculous piece of crap department ever. I'm tired... we're all tired- stop putting night meetings that are an hour away on us last minute. I'm sooo fired up right now. I decided to work up until the latest possible day so that I can save my all leave for when the baby is actually here but it's getting harder and harder to convince myself that =(
