If you’re willing to work in a public school, the salaries and benefits are pretty good. If you’re going to be an employee of a yeshiva or a Jewish special ed program, they’re not going to be so good. There are other options such as P3 (in NYC) where you contract to a school district to teach/tutor, but you’re technically self-employed, which means you pay self-employment tax and have no benefits.
As for burnout, it depends on the population you’re working with, and I don’t just mean the students.
As for what the job entails, the range is very wide. You could be a classroom teacher with a small number of low-functioning students and several other adults in the room, or you could be co-teaching a class that has a number of students with learning disabilities. You could be working one-to-one or you could be working in a resource room.
