Have you ever tried to get a hold of the actual PERSON who made a bad policy decision? Or does "run-around" come to your mind? If HR wants to make a policy, fine, but we better be willing to stand behind it, answer questions and deal with the fall out.
Note that none of this deals with the actual true responsibility of the schools (educating children) or HR (providing and developing and retaining the best people for the company). It's all the administrative stuff that must be dealt with. Screw this up and people begin to distrust you on the other things.
