Facebook is secretly working on a new website called “Facebook at Work” to get a foothold in the office that will see the social network of more than 1 billion people compete directly with Google, Microsoft and LinkedIn.

The website, with the iconic blue and white theme, could enable users to chat with colleagues, connect with work contacts and collaborate on documents as with Google Drive and Microsoft applications. It will very much like Facebook – with a newsfeed and groups – but will allow users to keep their personal profile with its holiday photos, political rants and silly videos separate from their work identity.
