To a Crest spouter: I do not know one teacher who works 180 days and has only five 40-50 minute classes a day. My husband was a teacher and arrived at school one hour before the day started to make copies and prep for his day. He also came home about one hour after the school day and still had work to do. It is easy to think that teachers just show up, teach and walk out the door, but that is not the case.
