I saw this coming. The talks with New Chair about how "we only have the budget for you to teach (X number) of classes," were the first clue.
Then there was a ray of sunshine. "Please do additional training that will make you eligible to teach Q and R." I poured hours and hours of time into this; I wanted to be a team player. I did the extra reading. I revamped and revised my class. I encouraged my students to request the next class in the sequence, and ask their advisers to make it known that there was an interest in the second class.
I get told by New Chair and Dean, "You're a great teacher. You're an asset to [this institution]. We hope we can keep you."
Apparently that's not enough to stay employed.
