I tend to hear that from the higher ups… if you want to move up , who will then take your place. Though I’ve never seen this in practice. Many people have left or gone to other locations though those “below” them have never taken their spot. But rather transfers or new hires. So why is that statement always mentioned? I get it as a leadership challenge : are you developing your team to also be at your current level. But if no one truly wants to also be a leader. How much is that kept to keep yourself from moving up?!
