Which way to leap?

I don't know what to do, which way to go, in my job situation. Some
days it's crystal clear that I need to bail, other days it's clear I need to
stay and work at making this place what it can be.
On the one hand, I cannot stand one of the teachers. On the other hand, in
a school with 25 people in my department, it's a good bet I'd find at least
one I couldn't stand, and maybe more. And if you look at the fact that most
big schools have 80+ teachers, that's a lot of potential buttnuggets to have
to deal with. And while I don't entirely trust that she's going to
accomplish what she's trying to do, I really do like our Principal. I think
some of her decisions are stupid beyond all reason, but that's true of our
last Principal, too.

On the one hand, I hate some of what they're trying to to here. On the
other hand, I love some of what they're trying to do here. And which
one is more changes almost daily. I love that my Principal is dedicated to
both bringing the Arts back to education AND trying to make this school
academically rigorous. I don't always agree with the methods chosen to do
that, because sometimes I think the focus is too touchy-feely and not
academically sound enough. I'm frustrated that yesterday some guy from a
local tree charity was trying to figure out where to plant trees on our
campus to make it more woodsy (part of the Waldorf back-to-nature approach)
when we're not doing enough to kick the academic rigor up to where it needs
to be. But then today happened...

I was informed today that I'm being paid about $500 for the work I'm doing
in creating two college-level courses for next year, which I will teach.
And I was given a $5000 budget to get new books (and we really do need
them; the books we have had since I started here are mostly for kids WAY
under the ability of the students I'm teaching). How many schools are going
to give me that kind of power and responsibility? Not many, I have to say.
So do I reward that trust and stay, or do I set up the class and then bail
out, knowing I may never get to teach it elsewhere?

My students complain that only one other teacher in the entire school is as
strict as I am. First of all, I know that's BS, but secondly... I don't
care. It doesn't matter to me if Teacher X lets Student Dipdoo get away
with murder; he's not going to do it in my class, and if they can't handle
that, tough. On the other hand, I really wish some of these teachers would
get with the program and stop enabling bad behavior.
