You just have to realize that the problem is with her personal insecurity and has little to nothing to do with you.
And realize that if she refuses to listen to you trying to clue her in about the philosophy and methodology of your particular
school and insists upon being harsh and confrontational with the kids, those in charge WILL DEFINITELY notice and she won’t be there long.
They take things like how people treat the children very seriously and they will not tolerate her being verbally abusive and yelling at the kids.
Obviously she is an angry person with a ton of insecurity. If that were not the case she would have no need to lord it over anybody.
Just keep doing your job well and ignore her outbursts and cutting remarks since they have no foundation. You know what your doing and have years of experience and competency at your job.
Her opinion about the lack of alphabet soup after your name matters little in the long run. You’re working on that as best you can and the opinion of your superiors is what matters, NOT hers. If they didn’t think you were doing a good job they wouldn’t be asking you to clue her in. If she refuses to listen to you, that’s her problem.
Trust me, she’ll be gone shortly. Yelling at you like that, especially in front of the kids, is extremely unprofessional and you have every right to bring it to the attention of your supervisor when the time is right.
When dealing with children with problems, the rapport with and caring for them is FAR MORE important than who has what degree. These are qualities which don’t automatically come with any degree. It’s clear that you have them and she hasn’t a clue.
You’ll be there long after she’s gone. Just ignore her until then. You can’t change her and you certainly don’t need to be yelling back and just upsetting both yourself and he kids. You’re there for them. Just keep your attention on them and let her dig her own grave as far as this job is concerned. She doesn’t belong there and those in charge will recognize that the more she keeps shooting her mouth off.
