Who gets YOUR kids??

so this is a bit of a touchy subject but here it goes ... who gets YOUR kids?

i dont mean, in case of death, who gets your kids? i mean who gets to determine who gets access to your kids? how do YOU decide who gets your kids?

or do you?

What happens if you are assigned a teacher or principal who you don't connect with? or who you feel is not a positive influence to your child? how do you deal with that?

Please dont think i am teacher bashing because i am not! i know first hand what a demanding job it is to be in the classroom. i am simply looking for some insight as to what to do if you don't think your child has the right educational guidance...
