Is it always necessay for a manager to know the business��from the ground up�� ?Tell the reason in Business area.

Managers are not just the boss, they are the liason between upper management (owner, CEO, VP etc.) and employees. Managers must know the business they are directing. Otherwise they will run the business to the ground. They must have business management training.Managers help businesses achieve goals. These can be sales, environmental, expeansion etc. So they need have the respect of the employees. If the employees know more about the business than the manager, he will not have the respect, will not be a good leader and will achieve the goals upper management has proposed. I would never promote someone to management without a college degree in business or at least 5 years in my company. I prefer both. I also prefer accountants, I think they are the best prepared to be leaders.
