Thank you, but these relationships aren't sexual that I know of. They are just inappropriately close, such as the teacher inviting students to see movies, come to her house, offering them rides in her car, personal text and phone conversations, saying she loves them, etc. The teacher is treating teenage students like close adult friends and breaking school policy. It makes me uncomfortable, but as these relationships aren't sexual, I'm unsure what action to take.
You used the term "vengeful" which indicated to me that you have some fear about this individual. This is a serious red flag. As you know that there are district policies about associations between teachers, staff and students, some type of communication about this individual's conduct is still appropriate. You may want to discuss this matter with someone you know will maintain your anonymity. While your interaction with this individual may not have reached a physical level, the conduct you are describing falls into a category of behaviors known as "grooming" which is often a precursor to inappropriate physical conduct. Good teachers often have strong personal relationships with students, but those interactions are typically limited to contact that involves several youth at a time, the presence of at least one other adult (as in 30 or more years old) or in many cases a parent.
I use the word vengeful because when I told the teacher I was uncomfortable, she became upset and the next day told the principal I had threatened her, though I hadn't. Nothing more came of this, but that's why I want to remain anonymous. I'm worried about other students, because she forms these relationships with male students who have uninvolved or absent parents, spending lots of alone time with them, even taking them shopping and buying them things. I used to think she was being motherly, but now I'm not so sure.
Thank you so much for your insight. I will proceed cautiously and find more detailed information on the school's policies. I may ask a school faculty member to monitor the situation.
I encourage you to meet with a trusted adult who per your states rules qualifies as a mandated reporter for possible child abuse. You are a very brave individual. My sense is that you were able to protect yourself. Be brave and keep going.
