write a letter to my supervisor about bad behavior in class and we will not say any bad words in online class

Dear supervisor,

We do not think bad behavior is tolerable either and we will encourage others around us to support this idea as well. We know that it can be difficult for a teacher to handle these insignificant and it should be addressed. Foul language will also be restricted from our language and we will not use it in our online classes.

Yours sincerely,
