Many of us have experience with working in virual teams. I think you would agree that most of the time, it's not so effective as having the team together, in one office. We all know why - lack of face-to-face interaction, hence insufficient level of communication.
Working as project manager in a corporation, I haven't seen my team after 6 months of running the project with no chance to change it any time soon! We don't use webcams during our web meetings so only way how to follow body language is the speach.
Once I realized that team is not listening me and was a bit angry because of that. So I analyzed situation later that day and realized that my tone of voice was different as usual. Why? I was pretty tired (thanks to my neighbours partying last night ). So the next day I prepared myself with some voice exercises, checked some funny video to get to better mood. Only after that I joined the call. You can guess what happened. Better response
Ever since, I pay attention to it. Also, to the tone how my colleagues are speaking. I already know their baselines so I can pick up any discrepancies (pitch, cadence,...) and dig into it. I don't interrogate them, just want to make sure they understand the situation or know how to do some tasks.
What experience do you have? What clues are you following?
