I am the cofounder / CTO of a very small startup, ~4 people. We recently had to let go 2 people for differing reasons. As a result, we moved one engineer from working mostly on metrics to work on our web server. That employee is a direct report to me but is personal friends with our CEO, as am I; we're a small startup of mostly friends.
We have been discussing some technology changes in the wake of the company changes, and have had several meetings in the past week or so about this.
Last Saturday, the engineer and our CEO had brunch. They did not tell me that they were doing this ahead of time, and they discussed a number of work items. My employee told me last night that they had met, as well as which items they discussed, which I appreciate. When I asked our CEO afterwards what they discussed, he said that it was "just brunch." I said that the engineer had mentioned that they discussed a few work items and we then reviewed those.
We're a small startup, and I don't begrudge anybody their social time with anybody else, but am I wrong for feeling that they should have let me know that they were meeting, particularly if they were planning to discuss work items that I had a vote in? I appreciate that my employee let me know afterwards, but I also am a little wary that I was not included or notified except belatedly.
