I heard about this story:

https://www.abcactionnews.com/news/education/florida-teacher-says-she-was-fired-for-giving-zeros-to-students-who-didn-t-turn-in-work

The teacher was fired for giving students a 0 grade for homework that was never turned in. It appears the school has a policy of not giving anything less than a 50% regardless of what was done on the assignment. Should this teacher have been fired? What are your views of this policy?
