I don't understand the numbers. A typical highschool teacher is on campus from 7am to 3pm minimum. That is 40 hr/wk. That allows a 30min break for lunch and typically one hour "planning period" that is insufficient for handling all lesson planning, grading, and assessment stuffs. I'm left questioning the validity of the responses to the ATS. Multiple teachers I've talked with report earning less than minimum wage after counting all the everything they do. For the ATS responses to be counted, the "households that have completed all eight months of the Current Population Survey (CPS)." That feels like a pool of respondents that will self select out very busy people.
