As social media has become more important in the work place and for employees themselves, you may need to consider informing your employees in how they should or should not be using social media, whether it be in or outside of the workplace. If your organisation has just begun to use social media, do you have a policy in place for your employees? If you are using it to market your organisation, you may need to put in place some guidelines and terms of use to make sure that social media is being used appropriately for your organisation.
You need to consider your company brand, and how your employees may represent that brand in their use of social media. You need to be aware of what they maybe saying about your company online. Whether you want your employees to use social media as much, or as little as possible, you need to let them know your expectations.
