By definition, a professional is someone who does something for money. Thus there is no such thing as a professional public school teacher, because teaching is not what they do for money.

It always amuses me how the variations of the word “professional” are consistently misused. Lots of people don’t seem to know what “professional” means.

I once knew an amateur teacher (private highschool). He was a retired naval officer, and taught physics and math. He literally took no pay. For some sort of liability reasons, the school had to put him on the payroll, with a pittance nominally going to him. He donated that back to the school.
