Opening it, we discover "Ten Tips for Headship" and our jaw drops.
Tip 7, for instance: "Spend time on your own learning, ideally in a community with other heads. Time out for this is not stealing from the school, it's investing in it's (sic) future."
Or tip 8: "See if you can find a metaphor or symbol for what you want the school to be and use this regularly when you talk with others."
This stuff is not just banal, patronising and illiterate; it is also very bad advice. Much better to be available at all times and avoid metaphors like the plague. Try a good joke instead.
