* Public school districts: This is the most common employer, where teachers are employed by a local, state, or sometimes even federal government entity.
* Private schools: These schools can be religious, secular, or for-profit, and teachers are employed directly by the school itself.
* Charter schools: These publicly funded but independently operated schools employ teachers directly.
* Colleges and universities: Professors and instructors at higher education institutions are employed by these institutions.
* Online schools: Teachers employed by online schools work for the company or organization running the online program.
Ultimately, while the employer varies, teachers' primary responsibility is to their students and their learning. Their work serves the broader community as well, contributing to societal well-being and future generations.
