How to Disconnect on LinkedIn
LinkedIn is a social network that encourages people to make business connections in a variety of fields to further their careers. If you continue to use LinkedIn after getting the job you want, however, you may want to remove some of your previous connections to prevent your new employer from seeing them. You can remove a LinkedIn connection from the "Contacts" screen.
Navigate in your Web browser to LinkedIn.com, and sign in to view your account home page.
Click the "Contacts" link at the top of the page. This displays your list of LinkedIn connections.
Select the "Remove Connections" link in the upper-right corner of the page.
Click the check box next to the name of the LinkedIn connection that you want to remove.
Choose the blue "Remove Connections" box in the right side of the page.
Press the "Yes, remove them" button to confirm.
