Light Work vs Heavy Work: Why Some Work Drains You and Some Doesn't

Think about the first months with a newborn. You’re sleeping in two-hour stretches, feeding around the clock, barely eating a hot meal. By any measure it’s exhausting. And yet many mothers describe a strange fuel running underneath it all. Love keeps them going.

Now think about a three-hour admin session on something you resent. Nothing physically hard. You come out of it flat.

Same person. Very different energy cost. That’s the difference between light work and heavy work.

What is light work vs heavy work?

Light work is work you’re aligned with. It might be long, difficult or high-stakes, but it gives some energy back. Heavy work is work you’re fighting, through obligation, friction or a poor fit, and even short stints drain you.

The distinction isn’t about effort. It’s about the energy cost of resistance. Doing something you care about, with full commitment, can feel energising even when it’s hard. Doing something you don’t want to do, even for a short time, can feel depleting.

Does research support the idea?

Not under these names. Light and heavy work is my framework. But several well-established lines of research point in the same direction.

Demands drain, resources restore

The job demands-resources model is one of the most widely used frameworks in workplace health. It suggests job demands, such as workload and time pressure, are mainly linked to exhaustion, while job resources, such as autonomy, support and feedback, are linked to engagement. A large multi-sample study found burnout was mainly predicted by demands (and a lack of resources), while engagement was predicted by resources.

In plain terms: the same workload feels very different depending on whether you have control, support and meaning alongside it. Two founders with identical calendars can end the week in completely different states, because one is carrying demands alone and the other has the resources to meet them.

Harmonious vs obsessive passion

Psychologist Robert Vallerand and colleagues describe two kinds of passion for an activity. Harmonious passion is when you love something and feel in control of how it fits into your life. Obsessive passion is when you love something but feel compelled by it, so it starts to control you.

A 2015 meta-analysis of 94 studies found harmonious passion was linked to positive outcomes such as positive emotions, flow and performance. Obsessive passion was linked to both positive and negative outcomes, including negative emotions and rumination.

That’s an important nuance. Light work isn’t just “work you love”. It’s work you love and also feel free in. Even work you’re passionate about can become heavy if it takes over everything else.

What are the signs you’re carrying too much heavy work?

You might be doing too much heavy work if:

• you feel drained by tasks that aren’t objectively hard
• you procrastinate on the same types of work every week
• you feel resentful, not just tired
• you’re working long hours on things that don’t move the business
• you’ve stopped feeling excited about a win
• rest doesn’t seem to refill you

These overlap with signs of burnout. That’s not a coincidence. A business made mostly of heavy work is a burnout factory.

How do you tell light work from heavy work?

Use this quick check on any task.

Light or heavy? A task check

How do you shift your mix towards light work?

You won’t eliminate heavy work completely. Every business has invoices and tax returns. The aim is to shift the balance.

1. Audit your week

List everything you did last week and mark each item light or heavy. Most founders find a handful of heavy tasks eat a disproportionate share of their energy.

2. Cut, delegate or redesign heavy tasks

For each heavy task, ask three questions. Can I cut it? Can someone else do it at 80% of my standard? Can I change how I do it so it feels lighter, for example by batching it, pairing it with something enjoyable or changing the format?

3. Add resources, not just remove demands

Sometimes heavy work becomes light work with more support: a template, a clearer brief, a team member who shares it, or more control over when and how you do it.

4. Protect light work from becoming obsessive

Keep boundaries around the work you love. Light work still needs an end time, rest and a life outside it. Research links mentally switching off from work after hours to better recovery and sleep.

5. Check the reason underneath

Sometimes heavy work is heavy because it’s taking you somewhere you don’t actually want to go. That’s worth noticing. It may be a sign your business, offer or role needs to change.

What does redesigning heavy work look like?

Here are common heavy tasks founders mention, and ways to make them lighter.

Heavy task redesigns (examples) Weekly content creation | Heavy: staring at a blank page every day | Lighter: batch one morning a fortnight, record voice notes and have them edited Sales follow-ups | Heavy: chasing people who’ve gone quiet | Lighter: a simple sequence of templates, sent in one block twice a week Bookkeeping | Heavy: a monthly scramble through receipts | Lighter: a bookkeeper, or a 20-minute weekly slot with a good podcast Team updates | Heavy: answering the same questions all week | Lighter: one short recorded update on Monday, questions in one thread Client onboarding | Heavy: reinventing it every time | Lighter: a checklist and welcome pack someone else can run

You’ll notice none of these remove the work entirely. They change the friction, the timing or who carries it. That’s often enough to turn something you dread into something you barely notice.

Why does this matter so much for women?

Many women were taught to be good at everything, including the things that drain them. We’re often praised for pushing through, for saying yes and for carrying more than our share. Most of the high-achieving women I work with are stuck in that push mode, and they’re exhausted by it.

The reframe I offer them is simple. You’re not failing to work hard enough. You may be working hard at the wrong things.

Where can you get support to redesign your work?

Shifting from heavy to light work often means changing your offer, your role, your team or your boundaries. That’s hard to do alone. The Conscious Founders Club is my 12-week group coaching experience for founders, CEOs and high-performing women, with six frameworks and live group calls every two weeks. Together we redesign how you work and lead, so your energy comes back and stays. If you’re not sure where to start, book a call with me.

“even though my desires and vision were still there, my body just couldn't keep up. My mind wanted to go here... my energy couldn't follow and that was confronting.”
