The teacher in that example had 13 years of service and worked in one of the better paying public schools in New Jersey. She said she was paid pretty highly at around $60K (iirc). I do remember there was a kind of pecking order where more entry level teachers would make lesson plans, but the senior teachers still had to help the younger teachers learn how to do it, and sometimes do it themselves when nobody else could (teachers might trade between each other what extra work they needed).
