The disruptive child is another one of those incidents where we are aware it could be OUR children being talked about, or requested to be moved away from their precious snowflake..
WE all want the best for our children, and no, it isn't right for the school to use other children as support for ours, however, our kids can't be ostracised or made to sit on their own in a corner with no interaction.
Its covert disablism.. again, replace the 'ism' and see if its acceptable.
Move my child away from that muslim
Move my child away from that jewish boy
Move my child away from that Gay boy
Move my child away from that Black/Pakistani/Chinese boy.
Move my child away from that disabled boy.
Its discrimination, they only want their child moved because they don't like something about who that child is.. and its not ok.
What they SHOULD be doing, is asking if the school is adequately supporting the students to enable them all to work well with each other.
If they other child is being a bully, then its different because thats about protecting your child, but again, the school is failing them.
If the ONLY reason, like in that thread, you want your child moved is because you dont like that your child is sat next to someone disruptive/chatterbox/not doing work then you need to ask yourself if you're being discriminatory.
