As a teacher, youre responsibility is to teach not only academic matters but as well as character growth. Remind the students about the consequences of bullying from time to time. Check on your students, ask them if they're having troubles at school. Let them open up to you. Being a teacher is not only a profession, you must be a mother to the class. Deal with the issues just like how moms would do it. If bullying is encountered, report it and talk to the children. Give the right discipline to the bullies and encourage the bullied person. That way, you can help minimize the cases of bullying as a teacher.
Good day! ٩(^ᴗ^)۶
