Most of the public conversation about four-day work weeks has been about wellbeing. The pitch goes: people are burnt out, mental health is fraying, the modern workplace is unsustainable, and giving people Friday back is one of the more humane things a leader can do. All of that is true. None of it is the most interesting thing about operating a four-day week.
The most interesting thing is what it does to your hiring.
We've operated four days a week, fully remote, since 2022. In that time we've hired tens of senior people across SEO, paid media, digital PR and operations. The thing that's changed in our hiring funnel isn't volume — though that did increase — but the calibre of the people who self-select into the conversation in the first place. The four-day week is, structurally, a filter. It changes who gets to the top of your funnel and who walks away when they hear the offer. That filter is more valuable than the wellbeing benefits, and it's the part that gets the least airtime.
This is the case for thinking of the four-day week as a hiring strategy.
The applicant pool changes
When we advertise a senior role, we now get applicants from a different pool than we did when we operated a five-day week. A meaningful proportion are people who, at the same skill level and seniority, could be earning more in a five-day role at a larger agency. They're choosing a slightly lower-paid opportunity at a smaller shop because the four-day week is, for them, a step-change in their quality of life.
This produces an interesting effect. The applicants who self-select into the conversation are disproportionately people who've already worked out that compounding their time matters more than compounding their salary. Within senior knowledge work, this tends to correlate with a particular set of dispositions: confidence in their own value, comfort with output-based work, lower tolerance for theatre, and — usefully — a strong instinct for prioritisation.
Those aren't perks. Those are dispositions that meaningfully change how an operation runs.
The applicants you lose are useful information
Equally important: who walks away.
The first category is people who've built an identity around long hours. The five-day week, particularly in agency work, has historically been a vehicle for a particular kind of professional self-image — "I work hard, I'm always on, I'm always in the office, that's what makes me valuable". For those applicants, our offer doesn't compute. They want a role that lets them perform diligence. We can't offer that.
The second category is people who, on closer examination, need the structure of a five-day week to function. Output-based work, async-first communication, and a four-day rhythm requires a particular kind of self-direction. Some genuinely talented people don't have that, and the four-day week filters them out before we get to discover it the expensive way, six months in.
In both cases, we lose people we wouldn't have benefited from hiring anyway. The five-day week was, retrospectively, a very poor filter. The four-day week is a much better one.
The compounding effect
The interesting consequence of running a tighter hiring filter is what it does to the team over time.
If your hiring filter consistently produces senior, self-directed, output-oriented operators, the operating model that team can sustain is meaningfully different from one staffed by people requiring more supervision. Decisions can be pushed further down the org. Layers of management become less necessary. Meetings are fewer because the prerequisites for fewer meetings — clear writing, async habits, mutual trust on outcomes — are present in the people you've hired.
This compounds in two directions.
It compounds outward, because the operating model becomes self-reinforcing: you can hire more senior, more self-directed people because the operating model rewards them. New hires step into a structure where their disposition is the default, not the exception. Onboarding is faster. Cultural assimilation is easier.
It compounds inward, because as the model strengthens, the four-day week becomes operationally more sustainable. The biggest risk to a four-day week, in practice, isn't lost capacity — it's the slow erosion of the operating discipline required to make it work. Meetings creep back in. Email volumes grow. Synchronous expectations re-emerge. If your hiring isn't consistently bringing in people who reinforce the discipline, the four-day week dies of attrition. If it is, the discipline gets stronger.
We've been operating long enough to see both halves of this play out. (For the honest version of what broke in our first six months, I've written that separately.) In our first year on the four-day week we had to push back against operational drift fairly often. In year three we mostly don't. The model has become self-stabilising because the people in it are self-stabilising. That's the hiring filter doing its work.
The honest costs
A piece on this topic that didn't acknowledge the costs would be propaganda. Two things are real.
You have to actually pay people well. The four-day week works as a hiring filter, but it doesn't work as a substitute for compensation. If you try to use it as a way to pay people 20% less, you won't attract the senior calibre I've been describing. You'll attract the bottom half of the senior market, which gets you no operating advantage and a lot of operational fragility. We pay competitively. The four-day week is on top of that, not in lieu of it.
The hiring filter only works if the operating discipline is real. If you announce a four-day week but in practice everyone's checking Slack on Fridays and feeling guilty, you've created the worst of both worlds — none of the wellbeing benefits, all of the capacity loss, and a hiring proposition that's a lie. Senior operators figure that out within their first month and leave. The discipline must be authentically held by leadership, or the experiment will fail in ways that do real damage to the team.
Both costs are real. Both are within the operator's control. They're not dealbreakers. They're the actual work.
What I'd say to other agency leaders
The case for the four-day week as a wellbeing initiative is well-rehearsed. The case for it as a hiring strategy is less so, and I think it's the stronger case.
It's the cleanest way I've found to consistently attract senior, self-directed, output-oriented operators at the scale a small agency needs to thrive. Those people exist in the market. The traditional five-day-week operating model doesn't particularly attract them. The four-day model does — partly because it solves a real problem in their lives, partly because it signals an operating culture that values output over presence.
If you're running a small or mid-sized agency or services business and your single biggest constraint is talent — which it almost certainly is — the four-day week is worth considering primarily for the talent leverage. The wellbeing benefits are real. They're also the easier thing to measure and the easier thing to explain. The harder, more important benefit is what it does to who you can hire.
We've operated this way for going on four years now. The numbers continue to support the case. The team continues to be the strongest one I've ever built. I'll keep saying the four-day week is, primarily, a hiring strategy — because that's the part of the conversation that hasn't yet had its day in the sun, and I think it deserves one.
