Consider the volume of meetings happening daily globally. It is estimated that 55 million meetings happen every day in America alone*. Whatever the real number, we should assume this isn’t a minor source of tension. It’s a major culture warping issue that’s endemic and destabilising for 50% of the working population.
If the aim of your meeting is to achieve balanced, representative decisions (key ingredients of good culture) then you’ll fail if you let the diverters hog all the airtime.
