When my manager asks me to present what I did over the weekend to the team, that's a demand from my boss. He may or may not think it is, but there's a power dynamic involved here that can't be ignored, which is why I think it's an awful practice.
I answer "not much" and immediately pivot to giving a work status report before any followup question can happen, and my manager lets me get away with that. That's a little better, but it still starts every week off on the wrong foot.
