A few weeks ago, I wrote about the unstoppable trend towards mobile working and how, wherever you go, there are people perched with their laptop or talking business on their mobile phone. I had two concerns: lack of free WiFi coverage and a lack of consideration for ergonomic comfort. The day after that piece was published in this magazine I was on the Stansted Express when two chaps got on and started discussing their employer, a well-known facilities management company. Not only did they openly name the organisation several times but they talked about what they believed to be fraudulent practices and made derogatory remarks about senior execs.
