Tesco plans to roll out its internal communication tool Yammer to all of its 320,000 UK staff following a successful trial of the technology in its London stores.

Last month, Tesco launched trials of a new staff room concept at its flagship Lincoln Extra store featuring a Costa coffee bar, digital menu screens, Hudl stations and a healthy menu, with a view to a potential nationwide rollout. It includes digital signage that will show Tesco Yammer and display store-specific messages.
