I know my team and project manager. I was sent the contact of my on-boarding buddy who is on my team. In a matrix organization, it's common to not have any day-to-day contact with your manager. In my current organization, I have no idea who they are. I'm sure if I signed into the HR help portal and looked up by profile it'd say who is my manager, but I've had no interaction with them. Just got an email containing my year-end evaluation, no conversation. Maybe there name was in the email, maybe it was just the app that sent it.
