In a recent observation, I was told off by my line manager for telling a girl that I was disappointed in the grade she had achieved in her homework. Her level was three full levels under target, she is highly intelligent but lazy and by her own admission, had rushed through the work the night before despite having a week in which to do the work. I said one negative sentence on the subject stating that the grade was disappointing, nothing more extreme than that. She appeared not to care about my opinion either way, although this could have been not wanting to lose face, I suppose. I was told that I should have, "relied on my maternal instincts.". My instinct as a mother is that if my son went down three whole levels due to his own idleness and lack of organisation, he needs a kick up the butt!
Incidentally, the same manager was in the staff room last week, reading a kid's work out for the amusement of all and then ridiculing it. Apparently, that's fine.
