In business is withholding information for your own advantage the same as lying why or why not?
The answer is completely situation-dependent.

-In many situations it is important that information be kept confidential. Damage may occur to the company if it is thoughtlessly shared, even within the company.

-In other situations employees treat knowledge as power and use it or withhold it in their own best interests rather in the interest of the enterprise.
