The FT’s ‘Fast Lane’ columnist Tyler Brulee once wrote entertainingly about the problems it can cause when TV crews, interviewers and various hangers-on invade your office. They can be very nosy, get everywhere and be hard to control on occasion by sheer weight of numbers. Think carefully before you invite them into a working environment. If you do, ensure everybody in the office knows exactly what is going on and why, and make sure they have put away any sensitive corporate information, or embarrassing pictures. If there is a problem, never let your anger show. With video-recording smartphones now ubiquitous and TV cameras possibly running, you should always operate on the basis that your outburst could find its way onto YouTube. Keep cool and smile even while being as firm and unyielding as you need to be.
