Had It in Holland Park

    I hold no brief for silly superstition, but I would hope that this instance was merely an excuse to get rid of a supply teacher that was not up to snuff in other regards.
    If not, if the policy is actually to stop using a supply teacher on the first mistake, I despair of supply teachers ever improving.
    If she is any good as a teacher, help her to understand what she did wrong, get her to agree not to do it again, then send her back out,
