1. If you knew about the environment and chose to work there,
then you should live with the choice - no complaints. A
complete newbie might have a legitimate complaint, IF a record
of memos supported an ongoing situation.
2. A field trip is just another activity, like a test or a
research report. You assign it and offer assistance for the
students if they want it. If they complete it, they earn
grades. If they don't complete it, no problem - they don't
earn the grades. Fussing at them doesn't change their
attitudes, but only makes you as the instructor seem
dictatorial and a whiner.
3. If you chose to walk into a classroom without at least a
letter of intent from the college, then you chose to work on a
"handshake agreement". It's worth just everything that implies
(good and bad). I suspect it's worth exactly the worth of this
institution - not very much.
4. They haven't fired you for 2 reasons: 1) they don't want to
hire your replacement for that class, and 2) someone in that
administration is trying to save your teaching career - being
fired from 2 classes would definitely be a deal breaker if you
applied somewhere else.
Sue the institution? You are welcome to consult a lawyer, but
I very strongly suggest you find someone experienced in
educational law, not a normal lawyer. The employment rules are
different in education area.
