Anything short of that fails. Fear secures some managers in their position. On the other hand, the managers that issue orders change fairly frequently, as a flawed order is carried out with an unforeseen consequence. As a consequence the rule for managers is to not make any changes. Don't issue orders if you want to remain in your position.
Fear also avoids the sometimes embarrassing questions from subordinates.
This operates throughout the company. Alliances are imperative between managers and between employees and the politics are hateful and spiteful. Everyone views each action in light of the politics involved and not from the perspective of the customer. Coming to work is not an enjoyable experience. Your stomach is tied up in knots.
