Is this enough to get a teacher fired!!! lol (just wondering)?

Is she a new teacher? She could be fired if she continues to the point that parents complain. She shouldn't be saying Shut up -- she's setting a very bad example. She could have been having a really bad day, but if her behavior and language continue like that then a group of you should go to a counselor or the principal and say that the teacher is always in a bad mood and maybe needs some help. If she's an older teacher she probably has tenure and there isn't much you can do.
