Fill the need is an OG mantra that has been used to keep managers on top of critical issues for decades. If you see something that needs attention, either re-purpose some staff or do it yourself. Just don’t get into the habit of doing everything you see. You are not an effective manager if you are constantly doing hourly functions and a Lazy staff member might even take advantage of a hard working manager. Fill the need now, deal with the lazies, later.
