KinderCare Education review: abusive teacher

Hello I am not sure if this is the right department I should be writing to however I have a concern. many years ago maybe like 5 my sister had a child enrolled at kinder care learning center in corpus Christi texas on everhart rd. Her child was there for maybe a year or so in the process she became friends with one of the teachers there who told her another techer named Matilda Tervino had been fired for hitting a child with some type of utensil. Well last week she went back to see if they had room for her new child and saw that same teacher who had been fired back working. so she did not enroll but also was wondering whats the policy on rehiring staff that has been fired for reasons like that and she didn't know if she could ask the director about it. thank you for your time today
