A W-9 is a tax form to provide your ss# or other tax id to someone who will be paying you money but not as an employee.  An employee fills out a W-2 form instead.

An employee fills out a W-4.  If you get dividends, interest or royalties, you are supposed to fill out a W-9 with your social security number so the payer can send a Form 1099 to the IRS.
