She ruffled more feathers than Jeanie C. Riley at the Harper Valley PTA!
For the sake of future students, it’s good that she rocked everybody’s boat. For her own sake, she may regret not being more diplomatic. Some of those ‘lousy teachers’ will try to get even with poor recommendations. It may not matter to a gal this poised, confident and articulate. She was not brought up to be fearful of authority. That’s often a plus in the longrun.
On the other hand, potential employers will be a little leery of boat rockers, who go outside of normal channels to address their grievances.
