For instance if you had been teaching honors/AP seniors for the past five years, and you were assigned all essential freshmen (low-track) courses this year, or if you have been teaching 6th and you were assigned K (and didn't want it) etc. Would it make a difference to you if they had a good justification for the switch? What if it were just 1 year? What if it were indefinitely? Is there any assignment that would cause to leave your school?
