Vouching for someone takes three words and can change their whole year: “They’re with us.”

A newcomer spends an enormous amount of energy wondering whether they are allowed to be there. Someone established saying plainly that this person belongs ends that question in a second, and it costs the speaker essentially nothing. You probably remember who did it for you, and you probably remember who did not.

If somebody new is hovering at the edge of your team or your table, say out loud that they are with you. Use their name in front of the others. That one sentence can carry a person through months.
