#5 teacher fired

A teacher fired for giving a zero and breaking the "no zero's" agreement. he clams that the student didn't hand in the assignment so he put a zero down. I personally don't see what he did wrong if the kid failed to meet the dead line then he deserved it. In the real world if something is due you have it in on time no excusses. the guy did nothing wrong unless preparing kids for the real world is a crime.
