Anguille, I actually went through the same thing a few months ago. I was working full-time AND going to school full-time. I was fired from the job because my school schedule would no longer allow me to work, and the bank refused to work with my schedule.
When I applied for unemployment, they told me that I was not able to work 40 hours a week. I told them it was not their decision on how much I was able to work, and I asked if they had ever heard of a thing called "night shift." It annoyed me to no end because I saw plenty of deadbeats waiting in line to get their benefits paid, people who obviously not looking for jobs but still getting the benefits.
