There are all kinds of leaders: under-sharers, selective-sharers, I thought I shared-sharers, I thought someone else shared that-sharers, never (do I even have a boss?)-sharers. You get the point. If you lead people, you need to share relevant work information. Share it even if your team receives information from someone/somewhere else. Talk about it. Do you understand it? Does your team understand it? Can you all execute it? When you think everyone has received and processed the message, share it again.
