The 3.5-Day Workweek: What Actually Happens After 36 Months

I haven't worked a full five-day week in over 36 months. My income kept climbing. My business kept growing. If anything, I'm more productive, more creative, and more present than I was when I was grinding through 50-hour weeks and calling it discipline.

The 3.5-day workweek is a structural decision about what kind of life I'm building. And the data behind reduced work hours suggests I'm far from alone in proving it works.

How I Actually Structure a 3.5-Day Workweek

Let me be specific, because vague "work less" advice is useless without architecture.

My work happens in 3.5 days: Monday through Wednesday are full days, Thursday is a half day. Friday through Sunday are off. Not "catching up on email" off. Not "just one quick call" off. Off.

Inside those 3.5 days, I run CTOx (a multimillion-dollar business helping fractional CTOs build $500K+ practices), coach clients, create content, and manage the operations that keep everything moving. I have a 6-year-old son, Pierce, and a partner, Mike. The 3.5-day structure exists because they exist. I designed the business to fit the life.

Here's what makes this work: ruthless elimination. Every quarter, I run what I call an energy audit. I look at every recurring commitment, every project, every meeting on my calendar and ask two questions: Does this generate energy or drain it? Does this move toward what matters or away from it?

Anything that drains and doesn't move forward gets cut. Not delegated. Not optimized. Cut. This is multiplication by subtraction, and it's the only reason 3.5 days work.

I work fewer hours because I figured out what to stop doing.

What the Research Says About Reduced Work Hours

The largest study on reduced work schedules tracked 2,896 employees across 141 organizations in six countries over 6 months. The result: 90% of companies retained the shorter schedule after the trial ended. The reason: it worked.

46% of leaders reported productivity remained stable, and 34% said it actually increased. Employee burnout dropped by 0.44 on a 1-5 scale. Job satisfaction rose by 0.52 on a 0-10 scale. Mental and physical health both improved measurably.

Microsoft Japan saw similar results when they trialed a four-day week: productivity jumped nearly 40%. Electricity costs fell 23%. Printing dropped almost 60%. The constraint forced clarity. When you have less time, you stop wasting it on things that don't matter.

Iceland's national trial of reduced hours (2015-2019, 2,500 workers) was called an "overwhelming success." Worker wellbeing increased across stress, burnout, health, and work-life balance. Productivity maintained or increased. The country subsequently moved toward broader adoption.

The pattern across every study is consistent: when you cut hours without cutting pay, people don't collapse. They focus. They eliminate the noise and protect the signal.

What Gets Eliminated (and What Doesn't)

People assume a shortened week means working at a frantic pace for fewer days. The 3.5-day workweek works because it forces decisions about what to stop doing.

Here's what I've eliminated over 36 months:

Meetings without decisions. If a meeting exists to "share updates," it becomes an async document. My meetings have agendas, time limits, and required outcomes. If we can't identify the decision being made, we cancel.

Reactivity cycles. I don't check email on Thursdays after noon, or on weekends. Urgent things rarely are. The things that feel urgent are usually someone else's poor planning landing on your calendar. Setting boundaries around reactivity is the single highest-leverage change I made.

Performative work. Reports nobody reads. Check-ins that exist because "we've always done them." Content created to fill a calendar rather than serve a purpose. I audit for performative work quarterly, and I'm still surprised by how much creeps back in.

The guilt tax. This is the invisible one. The energy spent feeling bad about not working. About taking Friday off while other founders grind. About picking Pierce up from school at 2:30 p.m. on a Wednesday. Guilt is a tax on your attention, and I stopped paying it.

What stays: client work that generates genuine impact. Creative work that feeds the vision. Strategic thinking that requires depth. Relationships that matter. Everything else gets cut, delegated, or automated.

What Happens to Income

This is the question everyone asks, and the honest answer is: my income went up.

The first 2 months felt terrifying. I was convinced clients would leave, opportunities would evaporate, and the business would contract. None of that happened. What happened instead was clarity.

When you have 3.5 days to generate revenue, you stop accepting work that pays but doesn't align. You raise your rates because your time is genuinely scarce. You say no to projects that would expand your hours but not your impact. You become more valuable because you're less available.

The research supports this. UK four-day week trial participants reported that more than a year later, they still loved the arrangement. Companies saw improved efficiency, lower turnover, and in many cases, revenue growth. The constraint refines the bottom line.

The 3.5-day workweek compressed my business into the hours that actually matter.

How to Start (If 5 Days Feels Non-Negotiable)

You don't have to leap from 5 days to 3.5. In fact, I wouldn't recommend it. Here's how I'd start:

Run an energy audit first. For 2 weeks, track every task and rate it: energy-generating or energy-draining? Mission-aligned or drift? You'll find 20-30% of your week is spent on things that produce nothing meaningful. That's your starting elimination list.

Protect one half-day. Pick one afternoon and make it sacred. No meetings, no email, no "quick calls." Use it for the deep work that actually moves your business forward, or use it for rest. Both are valid. Both are productive.

Measure output, not hours. Stop tracking how long you work. Start tracking what you produce. The shift from hours-worked to outcomes-delivered is the cognitive unlocking that makes reduced schedules possible.

Expect resistance from yourself. The hardest part of working less lives in your identity, not your logistics. If you've built your self-worth on being the hardest worker in the room, reducing your hours will feel like losing something. Notice that feeling. It's data about where your identity is tethered to performance rather than purpose.

The 3.5-Day Workweek Is an Act of Sovereignty

I could optimize my 3.5 days even further. I could squeeze more revenue per hour, more output per session, more impact per minute. But that would miss the entire point.

The 3.5-day workweek is an act of self-determination. It says: I refuse to build a business that consumes my life. I refuse to perform the grind for an audience that confuses busyness with importance. I refuse to treat my time, my energy, and my family as resources to be extracted.

The data backs it up. Reduced hours maintain or increase results across every major trial. But the reason I work this way has nothing to do with research. I work this way because I watched what happens to leaders who don't protect their time. I spent 8.5 years with Peter Diamandis building Abundance 360 from idea to acquisition, surrounded by the most ambitious people on the planet. The ones who lasted were the ones who knew when to stop.

You have permission to work less. 141 companies, 2,896 employees, six countries. The evidence is in. But the real evidence is quieter than a research trial. It's Pierce asking me to play on a Friday morning and my answer being yes without checking my calendar first.
