It's not just the pay.
It's also the constant walking on eggshells about every single topic
Administrators controlling how teachers run their classroom
Discipline being relegated to the teachers taking time away from teaching
Open communication between parents and teachers being abused with no help from administration
Lack of resources to properly cover certain topics
Lack of programs to properly educate different types of students in ways they need, ways that a traditional classroom environment doesn't provide.
