Speak up for the coworker who’s being talked over. It takes five words and earns you a friend for life.

Being talked over is small enough that objecting looks petty, which is exactly why it keeps happening to the same people. Somebody else naming it works immediately, because it costs nothing and nobody can really argue with it. The person it happened to remembers for years, since so few people bother. The whole intervention is about one sentence long.

When you hear somebody get cut off this week, say you want to hear what they were saying. Keep it brief and unbothered. Hand the floor back and let them use it.
