Noelle was the principal of a charter school and an employee at will. The head administrator imposed a rule requiring cafeteria workers to stamp the hands of children who did not have sufficient funds in their lunch accounts. Some of these children were entitled to free lunches, others needed to ask their parents to replenish their accounts. Noelle directed the cafeteria workers to stop this humiliating practice. The administrator fired her. Does Noelle have a valid claim for wrongful termination?
