I know the definition of constructive discharge, but I have a question. I am a high school Language Arts teacher. For the past twelve years, I have been assigned virtually nothing but the lowest-level classes of "at-risk" students (with two exceptions - that's two out of nearly 60 classes). Conditions have become intolerable for me, BUT it's been over a long stretch of time (I am guessing there's the rub). For CD to be an issue, it looks like it has to be a "sudden," deliberate change; obviously, my issue has developed over many years, but the negative effect on me is cumulatively the same. If my read on this is correct (meaning the amount of time may negate CD), are there other areas I could consider? Obviously, details are missing, but that's the broad picture. Thank you.
