I'm the project manager on a project that includes a former direct report of mine who has a tendency to show up late for meetings. When I managed him, I gave him occasional feedback about this tendency, but I clearly never succeeded in getting his attention.
Yesterday at our project meeting, he and another member of the team who works in the same building he works in arrived 11 minutes late. The other four of us who were in the meeting room, including one on the phone, had been waiting for these two people to arrive. We couldn't take up the first agenda item without them there, and so we waited for them.
I became increasingly agitated and had already announced my intention to cancel and reschedule the meeting when the two of them walked in. When I told them that I had canceled the meeting, my former direct report expressed exasperation: "What? You're canceling the meeting? But we're here now!" I lost my temper, reminded him that this was the second meeting I had had to cancel because of his lateness, said that I couldn't and wouldn't conduct a one-hour agenda in 50 minutes, and said, "You're late to meetings all the time. I'm not going to put up with this, and I'm going to talk to your manager about it." And then I left the room.
I did send an email to his manager (another former direct report of mine), but the last time this happened, I'm not sure that she ever even spoke to him about it, and I'm not counting on my email doing any good.
I am interested in hearing suggestions and strategies for a project manager to deal with aberrant behavior from team members in the absence of any role power. I think part of what is going on here may be that this guy realizes that I no longer have any power over him since I am no longer his manager. But his behavior is wasting my time and the time of other team members, and it is affecting the progress of the project.
