What is a Mother Supposed To Do???

Image via Wikipedia I never did this before. I never asked for help so openly, never demanded attention. I am the quiet/shy type. But not today, Not anymore. And you'll understand why. But first of all, please understand that now, when I am writing this, I am feeling over-emotional. I will write, maybe, inflamable words. Well, I hope to be able to write at all, so many feeling are playing the hora in my gut that it is difficult for me to swallow, let alone think. I am asking beforehand for forgiveness if I'll offend somebody with this post. This is NOT my intention and I speak from the bottom of a mother's heart.
So, the story goes like this: yesterday evening I was summoned by one of the mothers to an urgent meeting c0ncerning the welfare of our kids. In the beginning I thought it will be about the kindergarten's teacher, there are some issues going on with her and the parents want her out. But that's another story, for another time...The shocking news we were presented with say that the kids will have a new teacher's helper on Fridays. Nothing spectacular, you'll say...The problem is that this particular person was all over the media a few months ago because she had TUBERCULOSIS and she infected eight or nine kids from the kindergartens she worked in!!!!! Four kids, I think, are still hospitalized and are being treated!!!!!!!!!!!!!!!!!!!!!!!! And before you say anything, please google the disease and read about it. I did it last night and wasn't able to take it out from my head since...
It still seems surrealistic, I mean, no sane person from the City Council or Ministry of Education could send her back to work with kids! And I don't care if somebody says that she's been treated ot things like this, I am not ready to take any chances. I now I am subjective but I don't think it is fair. A child is so vulnerable, they don't even now how to protect themselves. They will hug and kiss her and cuddle her because this is what kids do...And she had tuberculosis, for God's sake! I don't say, throw her to the lions, no way, I'm just saying the persons responsible for her must find her another workplace. I don't even know if she is supposed to work with kids...God, I think I am going mad...
Of course we wrote a letter to the City Council and said in it that no kids will pass the kindergarten's gate on Friday and they promised us they "will take into consideration our request", you know the drill. But what bothers me, really-really bothers me is the fact that we are faced with such a situation. I mean, O.K., I could take Maya to another kindergarten, but what about the principle? The fact that we didn't have an official version of the story, that we had to hear from somedoby that told somebody that the teacher's helper had such a disease. I think it would be our right to know, for our children's sake and decide what to do accordingly. What worries me is the fact that the City Councildid this behind our back, and only God know what other things are lurking there! Are they allowed to do such a thing? Forget about the fact that Maya's new theacher's gives the impression of an alien from outer space. By the way, Maya doesn'r even now who her teacher is, because she didn't present herself in front of the kids. Tho other Israeli born parents say also tha her Hebrew is gramatically incorrect. Come on, I said , give the lady a chance! At least stupidity and ignorance are not contagious, are they?
So, what would you do, as a parent, would you be in my place? Please, I need your opinions and support!
I want to believe that I am not alone. That my words have power, that I am listened to. My daughter Maya and I need your advice and strenght, we need you by our side.
What would you do in this situation?
