7 weeks in and a curriculum change???

So here's the tale of the day.  It's seven weeks into our school year.  By this point, as teachers, we've planned out our lessons/units.  So what happens last night?  Our math teachers are called to a mandatory meeting in which the superintendent drops the bomb that the math curriculum has COMPLETELY changed.  There was 1 thing from the old curriculum map that was still the same... the rest was different.  As for the next unit, there were 2 things the same. 
Some classic comments our superintendent said:
When asked when the curriculum was to be implemented and when teachers were suppose to plan for all these changes, he responded with saying, "Tomorrow.  If it was me, I'd go home and write up 3 lessons for the rest of the week and then spend the weekend planning for the next few weeks.  Now, I know that many of you don't like to work on the weekend and have lives outside of school..."  SERIOUSLY?!  Is he implying that all his teachers are lazy?!  We work each night and each weekend, but that's not good enough for him.
Another comment was that he could "come in tomorrow and teach all your classes" because teaching is just that easy.
He is SOOOOOOO frustrating.  I don't think he could answer a question with a straight answer to save his life.  Such a politician!!!!!  He should just get out of education before he ruins our school district anymore.  If he pushes any more PHENOMENAL teachers away from out district, our poor students will suffer the consequences.  This is very upsetting.  I wish I could find a way to protest...
