Mrs. Lujano hears multiple rumors from students that Joseph, one of her students, has been vaping on the playground and encouraging others to vape as well. The teacher approaches this situation by sending out a letter to all grade level parents encouraging parents to talk to their students about the dangers of vaping, without consent from administration. Mrs. Lujano feels uncomfortable speaking about vaping with the students and hoped that parents would speak individually with their children after receiving the letter. Upon receiving feedback from parents, it was clear that not all of them felt comfortable speaking with their children on the topic of vaping. Which Model Code of Ethics did the teacher not utilize in this situation?
