Managers and decision making

I would like answers to these questions in your own writing instead of cutting and pasting a lot of Internet material.

What is a Manager?

Class, based on what we know from the Griffin text, is everyone considered a manager? Why, or why not?

Managerial Ethics
There is a great deal of pressure on CEOs in recent years to use moral criteria in making decisions. Some observers are concerned that too much emphasis on ethics will lead to less aggressive and competitive behavior, which may adversely affect profitability.
