Is there a right choice?

Well things at work have gotten even worse.  The more I have to deal with my principal, and the more she thinks she needs to deal with me, the worse it gets.  I'm not sure why she thought she had the right personality to be in administration, but if you're so scared to give honest feedback that your teachers don't know what you want from them, and if you punish them for asking questions, you probably aren't doing a great job.

I've been trying to to my best at work, but focus on being happy at home.  Once I get home, I try not to think about work (which is why I haven't been updating on here again) and I try to make the most of every moment, which is probably a good plan anyway.

Anyway, my husband has been urging me to quit (something I probably can't do right now and let us keep our home) or write her supervisor (someone I have no relationship with) and it kind of got me thinking about if there is a *right* response in this situation.  Is there someone I owe something to?  Is it my obligation to risk my job to alert the higher-ups (since this is a charter school, there's no union, and the main office is about an 8-hour drive away)?  If I'd been with the students longer, or felt like the school was allowing me to teach them better, I might feel like I should finish out the year for them, but I don't really feel like that.  I wonder if I'm being selfish by staying with the job because I need the money, when I know how badly the school is being run.  I am doing my best with the materials and perimeters I have to work with (I FINALLY got some instruments), so I don't think the students are really being deprived, but should the business know how badly their schools are being run?  Or should I just keep my head down and try to finish out the year?
