I have to agree with this post. The fact that educators have the power to do all of this appears to be amiss to me. My English teacher made a rule on her syllabus that she marks students for being even one minute late to class. However, she never enforced this rule. She herself came in two minutes late to class one time. Never mind the fact that most workplaces give a person a grace period. If she really did decide to enforce the rule, students couldn't do anything about it.
