Actually the OP hasn’t returned to clarify. In my initial response, I specifically stated if it was not great teacher take the class - if there was more to it look at alternatives. The thread had multiple people discussing incidences where they would choose not to have their student take the class. Your post that the teacher is employed therefore fine is also quite a leap. My experience is that abusive and incompetent teachers can stay in the classroom indefinitely. The OP has chosen to not clarify or expand on the nature of their concerns.
