How did you handle your kid's bully?

I was told by my daughters school the 'bully' was having a terrible time at home and them taking action could hinder her progress! 3 times i made appointments to speak to staff and 3 times I turned up and wasnt seen. In the end, my husband went to the school and refused to.leave until someone spoke with him about the situation. Eventually, he spoke with my daughters head of year who again pointed out the bully was part of a program to help her behaviour,so my husband said, 'well...if you dont sort it, we will. We've told our girl not to retaliate, but we'll tell her we understand if she does... and.. she has 5 cousins in her year group happy to back her up!!!' The teacher said...'oh Mr P....we cant condone that sort of behaviour' so hubs said, 'right... well I want that girl to apologise to my daughter and you to ensure us you will monitor it so it doesn't reoccur'
And... within 5 mins, our girl and the bully were pulled out of class and she got her appology in front of her Dad.....and it didn't happen again.
Shes 6ft tall now, a solider in the British army. She's Fit as F*ck, boxes, plays rugby....and i doubt anyone would choose to.pick on her these days.....
