I posted this in response to an article about companies losing productivity at work because of excessive Facebook usage by employees:

Companies should consider educating their employees on how to use Facebook, and social media generally to enhance not hinder their work performance. It’s not the tool but how people are using it that affects productivity.

One way to do this is to determine how Facebook will be used in the business and then allow only employees who enhance the company’s mission through Facebook to access it. Providing incentives to employees who successfully increase productivity through Facebook is another approach.

Facebook is like company provided cell phones. No company intends for them to be used primarily for personal calls, but rather for company business. I recommend using an incentive program rather than disciplinary action or restrictions.
