During the last period today, I encountered a distressing incident involving a group of female students who bullied another girl by pulling up her shirt, throwing her bookbag in the trash, and spreading rumors about her. The victim left my class in tears, and another teacher comforted her in the bathroom. After being informed about the incident, I addressed my class with a stern message against bullying, highlighting the dangers and consequences of such actions without naming the perpetrators directly, though their awareness was palpable. In the heat of the moment, I expressed my frustration in a manner that I later reflected on as unprofessional. I said "that is not gonna fuckin happen in my class". Given the small private school setting where I work, with many students coming from disadvantaged backgrounds, and the administration's current awareness of the incident without any disclosed consequences, I am seeking advice on how to navigate this situation effectively, including dealing with my own response and ensuring a safe, respectful environment for all students.
