Difficult people can disrupt any meeting, and we all know their frequent styles and behaviors from face-to-face meetings. These are people such as the Heavy Talker, the Technical Expert, and the Know It All. Below are some more difficult people that apply in the virtual meeting. (Of course many of these roles apply in the face-to-face meeting as well.)
The Late Comer. You need to have the virtual tool set up at least 15 minutes ahead for a long meeting (over 2 hours) and 10 minutes before for a shorter meeting. Welcome people as they come on. Then at the start time, tell everyone you will start now or wait for 2 more minutes, and then start. When new people come in, welcome them and move along.
