Most working professionals know the feeling. The calendar is full, the to-do list is under control, and yet by mid-afternoon there is very little left to give. Another productivity app rarely fixes it.
Time management assumes every hour is worth the same. In practice, an hour spent rested and focused produces far more than an hour spent tired, distracted or frustrated. What separates those two hours is energy.
The idea was popularised by Jim Loehr and Tony Schwartz, and later by Schwartz and Catherine McCarthy in their 2007 Harvard Business Review article, Manage Your Energy, Not Your Time. Their work describes four sources of energy that people draw on every working day. Each one gets used up, and each one can be renewed.
The Four Energies At Work
Each energy answers a simple question. When one runs low, the others usually feel it too.
| Energy | The question it answers | When it runs low |
|---|---|---|
| Physical Energy | Do I have enough fuel? | Afternoon crashes, constant tiredness, relying on caffeine to get through the day |
| Emotional Energy | How do I feel while I work? | Irritability, impatience, feeling on edge with colleagues |
| Mental Energy | Where is my attention going? | Scattered focus, reactive days, finding it hard to switch off |
| Purpose Energy | Why does this work matter to me? | Going through the motions, work that feels pointless |
The four are connected. A poor night’s sleep makes it harder to stay patient in a tense meeting. A week of back-to-back urgent requests leaves little room to think about what matters. Over time, a gap in one area quietly pulls the others down.
Two Sides Of The Same Account
It helps to think of energy like a bank account. Some habits make deposits: a proper night’s sleep, a short walk between meetings, a conversation with someone supportive, an hour of uninterrupted focus on meaningful work. Other patterns make withdrawals: late nights, skipped breaks, constant notifications, and tasks that feel low in value.
Many capable professionals have strong recharge habits and still feel depleted. Usually something is draining energy faster than their habits can replace it. Spotting that drain is often the most useful insight, because it points to a specific change worth making.
This is the thinking behind the Workplace Energy Profiler. Each of its four sections measures both the habits that recharge you and the patterns that drain you, so the results show where energy is coming from and where it is leaking out.
What Leaders and HR Teams Can Do
Energy is personal, and the working environment shapes it heavily. Leaders and HR teams can make a real difference with a few practical moves:
- Protect focus time. Agree on meeting-free blocks so people can do their most important work with full attention.
- Make breaks normal. When leaders step away from their desks, teams feel permission to do the same.
- Ask about energy in check-ins. A simple “What has been draining you lately?” opens a more useful conversation than a status update.
- Connect work to purpose. Regularly show people how their work makes a difference to customers, colleagues or the wider organisation.
- Look for team patterns. When several people share the same Energy Gap, the cause often lies in how work is organised, and a team conversation will help more than individual tips.
Why The Same Work Drains People Differently
Two colleagues can sit through the same meetings and leave with very different energy levels. One finds a day of back-to-back conversations energising, while the other needs quiet time to recover. Personality plays a large part in what recharges and what drains each person.
The WorkPlace Big Five Profile™ looks at five dimensions of personality in a work context. It helps individuals and teams understand their natural preferences and how these shape behaviour, energy and performance at work.
