1. Recognizing bullying
Repeated jokes, unwanted nicknames, organized exclusion and physical violence are all forms of the same problem.
Record dates, statements and witnesses. Documentation turns a complaint into a case.
2. Taking a systematic approach with the school
Request a formal meeting, bring the written record and ask for a response by a deadline. File everything officially.
If there is no response, the next step is the Conselho Tutelar, the Secretaria de Educação or the Ministério Público.
