I recently found out (today in fact when I was at work) that my daughter's teacher was fear mongering and in lack of better term campaigning in my childs classroom both on Tuesday as well as today

This school is no longer a voting center

Besides being highly unethical (daughter is in 4th grade) is there any state law that the teacher broke or crossed the line due to being a public employee on government property?

If not okay, I will still be talking to the principle in the morning.

It's a bump because I can't otherwise help.
