CN's job is starting to look a bit shaky
A useful senior management strategy (if you are an arsehole) is to employ a head kicker to roughen up a division and fire a lot of people, creating a lot of stress and anger among the remaining employees in the process.
Once the dirty deeds have been done, you fire the headkicker, blame everything bad on him, and hire Miss Pollyanna as the new manager. She is all sweetness and kindness and smoothes over all those furrowed brows among the employees. She gets everyone working productively and trusting her and the company again....... until the next time.
