The thing I read was they want a 18% pay increase, and haven't gotten a COL increase for a bunch of years. I looked up inflation over the past 10 years, and it has been a few percent a year, so I can see their point. OTOH, 18% is a LOT.
I am inclined to think elementary kids do not need more instructional time. I thought the length of day thing was just for elementary. I may be wrong. As a teacher I would be pissed to lose planning time because yes planning might only take 30 minutes or so a day, but you also have all the grading and meetings and stuff. IDK. I think teachers get paid fairly in general, overall, but as a sub, I also know you are Busy every minute kids are in your room, so you need other time to do grading, planning, have meetings, etc.
