Am i over reacting or doing the right thing?

I started working at a daycare about a month ago where I work in the toddler room and my daughter goes with me and she is in the younger 2's room. This is known for being a nicer daycare, with high prices and competent staff, but to me it seems like it has been let go and the director has gotten lazy. The teachers aren't drug tested and from what I heard more than half of the staff would fail, people come back from lunch break high, or they have had drinks at lunch and come back to work. The 4's teacher has been complained about many times and people have moved their kids out beause she will pinch them, kick them, and sream at them constantly (which I have seen her do) and the director won't fire her. Just Wednesday, a little girl in the 3's room had a seizure because nobody noticed her temp had gotten up to 107, when the teacher was trying to press the panic on, the director never responded, luckily the little girl was ok. The infant room teachers don't hold the babies except for feeding times, they just lay in cribs or on the floor the rest of the time. The creeper and crawler room fails to sanatize toys so out of 19 children, only 2 didn't get the hand foot and mouth disease that outbroke last week and now other rooms are getting it. They constantly accept kids no matter if it will cause them to shift children up or down that aren't ready yet. And to top it all off, my daughter cries everytime I drop her off and if she sees me walk by her room and she is picking up bad habits and acting a lot different (in a bad way) and I notice Wednesday that my daughters teacher was constantly out of the room and then when I go to get her at the end of the day, she has a huge pinch mark on her arm and neck, a big red skid mark up her spine and scratches on her hands that obviously nobody noticed or cared enough to make an accident report. When I confronted the directer about this she just waved it off like it wasn't a big deal. I owned an in home childcare before I went to this daycare where the kids loved coming to my home, and never cried when dropped off and always wanted to stay, and my husband and I are both beginning to think that I should go back to this and quit the daycare job because of these ordeals. Am I over reacting or is this what you would do also?
