Facebook is secretly working on a new website called “Facebook at Work” to get a foothold in the office that will compete directly with Google, Microsoft and LinkedIn. The Silicon Valley company is developing a new product designed to allow users to chat with colleagues, connect with professional contacts and collaborate over documents.

The new site will look very much like Facebook, but will allow users to keep their personal profile with its holiday photos, political rants and silly videos separate from their work identity. Facebook employees have long used the site in their daily work and expanding this to other companies has been discussed internally for some time.
