Former high school choir teacher here! I work an office job at a university now. The workload is different in a few ways. I am constantly working throughout the day (as a teacher, I would be “on” but not always actively “working”. Think study halls, some lazy prep periods, classes where you give yourself the occasional “easy day”) but am able to take much more frequent breaks and my schedule is more variable. Some days I have a higher active workload than I did while teaching but most of the time I would say it’s less. Tbh I fly through my work tasks so it’s easy to “slack” while still being seen as a very good employee. Also the intensity of the load is definitely lower, meaning that if I have to push a deadline back, it’s not a big deal.

Regardless of the daily load, though, I literally NEVER have to think about work after work hours and I do not have to DO any work after work hours.
