Social networks offer effective opportunities to network with business peers, join online business communities and enjoy thought leadership from others. Quintiles encourages employees to take advantage of these opportunities, but would strongly suggest that the appropriate venues for professional networking are business-oriented sites such as LinkedIn and Xing, rather than Facebook. Sites such as LinkedIn and Xing are designed and built with the business user in mind, so their structure and protocol is better equipped to support privacy and security for the business user.
