Can any modern news publishing business justify banning its staff from accessing social networking sites? While many national and regional newspapers have now reversed earlier decisions to ban workplace access to time-sapping Facebook—Johnston Press has set the clock back to 2007 and informed staff at The Scotsman and its other Edinburgh papers that Facebook is banned except in special cases. In a memo, (via Allmediascotland), JP management warn reporters that “a recent review” found more than half of the company’s entire outbound traffic is to Facebook so it has no choice but it stop people visiting. the Memo reads: “Journalists who require access should seek approval from their departmental head, who should contact the Group Helpdesk to have the permission restored.”
