At my school, I'd estimate that about 80% of the evening 1L students worked. I did.I won't say that you SHOULD get a job, but I can tell you that you are almost universally loathed by those who do work in your class. Everybody is cordial, but the class was pretty split in who hung out with whom - working with working, and non-working with non-working.
I work 3 days a week. I would say 50-75% of my class works. I think not working at all would make my overall work load a little light. I've also heard that firms don't like to hire evening students who don't work.
I'm sure they don't as it can show laziness or lack of drive to moany employers and others. But it's not like it is actually "part-time" schooling. I'm taking 11 credits, or 4 classes, as opposed to the 15 credits, or 5 classes, that the "full-time" day students take. The ABA recommends that full-time students don't work AT ALL. So I just get frustrated when people think part-time students who don't work are complete bums when in reality it's one less class. That's just my personal take. That is in no way meant to undermine those who have to work FT to support a family, spouse, children, etc. Most members of my families who are attorney's had to do it through night shcool.
