Cons
When you are consistently profitable, a 4th generation ex CEO, but still Chairman of the Board could start to believe he can't do anything wrong. You might implement a no facial hair policy. It sounds unreal, but forty people were pulled into executive offices and told they had to go home to shave the beards, mustaches, and goatees. People who had beards for 30 years had to lose them or fear for their job. Very few execs had the power/guts to not implement the policy. This culture of fear can also be seen in technical product shortcomings being swept under the rug. As an executive, why bring something unpleasant up when you could lose your bonus or job? By the time the shortcoming hits sales, you can have a few more years of employment and bonuses. What better way to create fear in your executive ranks than to publically dress down a demoted executive in front of employees during a division wide meeting for non performance? Accounts are king/queen here for better and for worse. Quarterly profit is all important. Short term savings are often achieved at a long term cost.
