I am at work, so lividly pissed off!!!! Here I am, 30, almost 31 weeks pregnant, doing these people a favor by working night shifts when it's not even my shift, I feel like shit, I'm tired and because some irresponsible asshole (that told me yesterday she was going to call off) calls off work, I am stuck here working a double!!!! 16 hours!!! from 10:30pm last night til 2:30pm today. WTF?!? I am so upset right now I could tell them to shove this job up their @$$!
