I know how you feel, I've been thinking about looking for a new job as well since my management has gone all crazy on me and most of the people I like working with are quitting by the fold.

I would look around and actually try to get another job before you quit. It's much more satisfying to know you have somewhere to go. I've quit plenty of jobs in my time and I will say you don't want to deal with looking for a job while being unemployed (still in debt because of that ). Anyway, good luck and tell those stuck up wenches to go smurf themselves when you finally quit. No one likes dealing with cliques...
