Teaching is almost recession-proof. Yes, there are teacher layoffs all over, but there are still plenty of jobs for the right teacher. Math and science teachers are always high in demand. Chances are less to be laid off if you teach one of these subjects. Special Education is another high demand teacher. Normally, there are more jobs for these teachers than there are teachers. Again, this makes for less chances of being laid off. Because of the budget cuts, they are increasing class size in K-3. That means, those grades will have fewer jobs, more chance to be laid off.
The bigger the state and district, the more need there is for teachers.
