I'm a teacher, and I definitely agree with the fact that it's TERRIBLE on your writing motivation. I honestly am so exhausted most days after work (long hours, mentally demanding, and constant creative problem-solving needed) that I can barely manage to make dinner, let alone get any writing done. It was better when I worked at the university level (more office time), but now I work high school, and it's a killer. Teacher burnout is also very real, and zaps creativity and motivation like you would not believe.
I used to have a couple a jobs that were much more writer-friendly. I did some graphic design for book layout (for educational materials) and I have more writing time there, and I also worked overnight shifts at an emergency youth shelter - which was, at times, incredibly emotionally demanding but quite often very slow (there were bursts of activity and then long 12-hour shifts of nothing when the kids were sleeping. I got a lot of writing done there, but like most social work, it was very hard and I wouldn't have been able to keep at it for long. I think working overnights gives you a lot of that down time, but also wrecks havoc on your body's natural clock. I felt like a vampire all the time, and I rarely saw friends & family. I wouldn't recommend it for longer than the 7 months I did it, but I think maybe others would feel differently about it (maybe they love the hours!).
