I have been working at my company for a number of years and have recently been accepted to begin training for another role where my principal duty will be to negotiate contracts with third parties. Part of my responsibilities are to host meetings with these vendors (currently through webex) to discuss current issues/future plans. I began the first few meetings with my prospective supervisor leading the discussion, and am now free to lead them without supervision.
My very first meeting I hosted began on the wrong foot, with the members being annoyed with the notification settings of the meeting. Unfortunately, although I was hosting this meeting, I was not the creator of it, and thus had no ability to change settings; the meeting progressed regardless. The final incident occurred shortly after I had heard some background noise in my house. It was about to be my moment to speak, and I did not want to ruin the meeting in anyway, so I got up with my laptop and moved to another room. Inexplicably, the meeting had closed during this and nobody was able to reenter. This caused a lot of issues for everyone as another meeting was unable to be recreated on short notice such that everyone was able to rejoin seamlessly. Some were unable to rejoin the new one for some reason. This caused further issues because meetings needed to be pushed back to accommodate this technical issue for others and suffice it so say: people were unhappy.
The fault was assumed to be mine, and I cannot deny this. As an alternate host I am technically able to end the session for everyone, but the confounding issue is that there were two other people that have this ability. I also have doubts that it was me because there is a confirmation dialog to prevent accidents like that. This still does not exonerate me because it is technically possible that some stroke of bad luck caused me to accidentally hit both the "end session" button and the confirmation right after.
Despite nobody having gone to the effort to retrieve any logs of the incident, I am now going to be in a meeting in a few days regarding my competency for this position. I am unsure if I should simply accept the blame and be more mindful of my work environment in the future to prevent any mistakes from occurring, or explain the full situation, that I am unsure if it even was my doing, and that it would be unfair for them to base their judgement of fitness based off of this. However, I fear that this will just be interpreted as passing off blame to someone else.
