I think this becomes a balance of peers. The psychological safety of one, may not necessarily be the psychological safety of another. Does the individual who wishes to speak up berate the underperforming co-worker for underperforming?

How can we get the new co-worker to start performing adequately? They are a member of the team, and unless there's some business motivation to fire or reassign them, they will remain a member of the team. I think the solution is to invest velocity to bring the co-worker up to the teams overall performance level.

That being said I do not condone being tolerant of intolerable performance, but I think that teams that consistently show grace and respect to each other will often yield the best results.

I suppose offering constructive criticism rather than beratement (is that even a word?) does require some minimum level or maturity. As does acknowledging the difference from the receiving end.

It's kind of the same discipline needed when pair programming and not ending up in a teacher/student dynamic. Words and actions need to delibrate and weighed, and the intent needs to be that the code base is above all else's ego
