(But that's a whole 'nother discussion, is it not?)
What exactly, is the nature of a teaching job? Essentially, it falls into 3 primary components: Those are often defined as being 1) an instructional time, 2) a tutoring, supervisory, or remedial time with students, 3) a parent conference and preparatory contact time, and/or a time to grade and evaluate work.
Over the years, teachers and boards of education needed to come to terms agreeing on how much time would be made available during the school day in order for all of this to occur in a reasonable manner. Added to this, of course, would be the obvious need for a lunch period. Complicating all of this would be that not all teaching jobs work out quite the same way. Music and vocational needs are not the same as academic needs. There also needed to be a between-building travel time allowance for the specialists, and oftentimes, an agreement of some sort for some set-aside evening parent conference times, now that so many parents are unable to meet during the day.
(There was often an implicit understanding that much school work might not get done during a school day, but the concept of after-school financial compensation for paper-grading, phone calls, etc..usually has not entered into discussions...yet. Maybe this topic SHOULD be discussed, if people want to call for a hard line on a strict, work-to-the contract model.)
The elephant in this chat room, however, seems to me to be not so much a discussion of what comprises a negotiated teacher's work day, but a teacher's fundamental right to have a part in the negotiation of that day at all.
You want to change the teacher work day? Work with them. If however, you want to introduce turn-back-the-clock, top-down, draconian dictates to them, you're just not going to get very far.
We might have a 19th century model for schools, but that does not mean it has to be a 19th century sweatshop; whether for students, or for school employees.
All just my opinions here, but believe me, I know a few others who just might agree...

Back to the banjo...
