It can be quite disruptive if a TV crew invades your office, particularly if it is for a higher-budget factual programme rather than just a quick news shot. 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 with your visitors, 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 if you have to be firm and unyielding, when drawing the line as to what is possible and what is not.
