"You break every rule of good man-management. You bully your weaker colleagues. You criticise colleagues in front of each other and in front of their officials. They can't answer back without appearing disrespectful, in front of others, to a woman and to a prime minister. You abuse that situation. You give little praise or credit, and you are too ready to blame others when things go wrong." From a memo written in 1981 by Sir John Hoskyns to the Prime Minister Margaret Thatcher.
