In many schools, opening revolves around the parents who have to be at work by eight. For instance, the doors open here at 7:15, and there is a large group waiting to get in, plus a long drop off line. That gives the parents time to get to work by eight. The end of the day, though, doesn’t match anyone’s schedules since the kids get out just before three, while the parents don’t get back in town until six-ish. If anything, dismissal revolves around the teachers who have put in eight of more hours already.
That's really funny. At the local public high school where I live, classes run from 7:35 am to 2:09 pm., with nine periods of 41 minutes each. But the teacher is obligated to work only five teaching periods and one non-teaching period. That adds up to to about 4 hours of actual work a day. Throw in another two periods to grade papers, and perhaps the taxpayers can get six to seven hours a day out of our "overworked" teachers. What a joke.
