We have a cm for our middle two children. My daughter has just told me our CM was so late picking them up tonight that they ended up sitting in the headteachers office. I have only been back at work for a few weeks and this is the fourth time she has been late but never so late they ended up in the headteachers office. I have mentioned time management on numerous occassions but it makes no difference. Feel really upset about this. What would you do??
