At the end of the second summer session, when I submitted my availability for work, I put down that if given an overnight, I would prefer to work the Friday one. The reason for this is that I have no classes or any real obligations on Fridays, so it wouldn't matter much if my brain was inoperative.
Last Wednesday, I was told that I was to be rescheduled to the Friday overnight from the Tuesday overnight beginning this week.
This morning, when I got up, I found messages on my voice mail telling me I missed my shift last night and that my immediate supervisor had to work in my place. He was less than happy about it, too.
I am tired of this shit.
