Question about subs

Just a kid who used to be bad in school.<br>I’m<br>Sorry.<br><br>I’m curious what is the protocol when a substitute gets mad at a kid in the class. Even if it’s just verbally.<br><br>Like let’s say a sub who has never seen a kid before in his life is subbing for a history class. And some random kid who has never been there disrupts class. Now let’s say the sub did the proper thing and written him up and sent him to the principal. <br><br>Who would the principal trust more. The sub or the random kid they have never seen before. Honestly it’s probably the sub.
