I liked this because he explains really well on how employees may be misjudging a manager's negative attitude on them because they don't understand the requirements of the business (or productization, for that matter). It often happens that you need to do something negative such as giving bad review, not approving some large piece of code which the employee thinks is beautifully written. Or even just fire someone. I've been on both sides, and now on the management side I see that employees usually don't realize the truth, and consequently have hard time getting a lesson out of the incident.
