There's an old saying that if you need something done, find the busiest person on the team. They'll get it done. Everyone knows who that person is. And so does the manager.
Researchers at Cornell and Northeastern recently confirmed what most of us have watched happen in real time — managers disproportionately pile extra work onto their most motivated employees.¹ Not out of malice. Out of a completely reasonable instinct: these people are capable, enthusiastic, and they care. Of course you ask them.
Except here's what's actually happening in that moment — on both sides of the room.
Your best people are receiving a signal that their enthusiasm is a liability. That caring more means getting more dumped on them. The research found their job satisfaction dropped more than three times faster than their less motivated colleagues when repeatedly pulled away from work they actually loved. Three times. That's not a workload problem. That's a fairness problem.
And across the room, the other 70% watched the whole thing go down. They saw exactly what happened. And their quiet, collective reaction was somewhere in the neighborhood of: don't make eye contact, don't make eye contact, don't make eye contact. Stay invisible, stay unburdened. Which means stay disengaged.
Two signals. One bad delegation decision.
Here's what changes when a best boss handles this differently. The engaged employee gets protected — and stays engaged. But the person on the fence? The one who's been watching from a safe distance? They get a chance. A real one. And when someone who hasn't been asked steps up and does good work — and gets recognized for it — something shifts. They come back a little more willing next time. Confidence compounds. Effort increases. And now you've got two people leaning in instead of one burning out.
Every delegation decision is a Momentum Moment™. The task is what's visible. But underneath it, you're shaping fairness, recognition, and whether people on the fence decide to lean in — or stay invisible.
Best bosses notice both layers.
Leadership happens in moments.™
