Recently I visited an intranet team who showed me how they use their internal social network to announce the passing away of a colleague, and to give everyone in the organization the opportunity to share their memories about that person.
Of course the immediate colleagues would be informed by their manager. Other employees had to rely on the printed newsletter, so they often learned quite late about the death of their colleague. In many cases, the funeral service had already taken place.
Since then, they have chosen to post the sad news on the social network, in a special “Obituaries’ group. The reactions have been overwhelmingly positive.
