My Teacher used profanity to students!?

My International Baccularette program in highschool. We have a teacher who cussed at my friends because they were going to a theater feild trip. their theater teacher gave an email to the the english teacher who cussed however she still was mad at the kids for not telling her at the way it was handled and CUSSED THEM OUT! what are some consequences because the kids told the principal and nothing happened except they fought?
