When we look at policy for LinkedIn, the same considerations as we discussed for other platforms are important.
Point-of-Contact: Your company should determine one person or a team internally that can handle all of LinkedIn interaction on the company page.
Content: Your company should set up rules on what company information, both sensitive and promotional, that employees are allowed to share among the various LinkedIn channels.
Comment Response: Your company should create a protocol on who responds to discussion boards, questions, and even product recommendations that come in, as well as how negative responses are handled.
LinkedIn is a place where many discussions take place. Consider setting up protocol on how employees should conduct themselves in threaded discussions.
