She has a short (45min?) planning period to start her day with her co-teacher, but as I understand it, it's nowhere enough. After that, her classes run back to back, yes. She has one meager lunch break lasting something like 15 minutes -- she actually started drinking Soylent for lunch because she doesn't have time for anything more complicated than that plus an apple. She gets up at 6:30am and doesn't really take time to eat breakfast either. It all sounds unbelievably stressful to me. It's very different from my own privileged life as a software developer.
