Account Department Vs Marketing Department

In three private company I have seen some same contradiction between the two department ”Accounts” and “Marketing”. As an IT person we have to work in these two departments.

Account Persons Think That:
01. Marketing department is fully polluted with dishonest
02. Marketing persons are always honest in their work.
03. Marketing executives and managers have no technical skill.
04. They expense a huge amount of money of company. Their facility should be reduced.
05. The account executives are honest and they work hard but pay small amount.

Marketing Department Think
01. Marketing Department earn money. They work hard for company. They increase customer and they have right to do many things
02. We earn money from buyer or customer and accounting person work with that money.
03. We increase the sale of company and we have productivity and account department have no productivity.

Over all I have to meet with these two departments. In these company I have seen that marketing department earns much money for company and they want their won account for their conveyance and other expenditure.
