In some states, once the third contract is offered to a public school teacher, s/he has earned tenure, which makes the process of terminating his or her employment onerous. I don't know how it works here, but I suspect that since she is in at least her fourth year at the Springfield district, she is tenured. Hopefully the district superintendent has what it takes to fire her. She really has no business teaching in a middle school. 

I actually don't care much that she engages in recreational intoxicants, but the drunk driving is a bridge too far. In my book, that's a crime of violence and makes one unfit for any number of jobs. (Just one more reason to be thankful I'm not dictator.)
