The Nine-Day Workweek

Every few years, the conversation about worktime settles on a new ideal. Lately, the four-day workweek has become an appealing concept. The pitch is that people get the same amount done in fewer hours, employees are happier, and productivity rises.
At the opposite end of the spectrum sits China’s infamous 996 schedule—9 a.m. to 9 p.m., six days a week—roughly the equivalent of squeezing nine normal workdays into one week.
How is it possible that we have two such extreme views of the appropriate work week?
Why the 996 Exists (and Why It Sometimes Works)
Why ask people to work the apparently insane 996 schedule? The first reason is that some industries move at a pace where speed is existential. Shave a month off development, and you win the market. Fall behind, and you’re forgotten.
Second, some work cannot be neatly parcelled out. A lead engineer, a key designer, or a senior integrator can’t hand over half a problem to someone else. Everything flows through them.
Third, the compensation structure makes the sacrifice rational. If someone believes that a few intense years will let them buy a home, retire early, or bootstrap a startup, you can’t dismiss that as irrational. There is also, for some, simply the thrill of taking on an incredible challenge with an incredible team.
The lesson here isn’t that 996 is good or bad, but that it makes sense in some special circumstances.
When the Four-Day Week Actually Works
There are jobs where a four-day week is a sensible design. In some roles, it’s rare for there to be five full days of essential work. Any extra time gets filled up with low-value tasks (or coffee breaks). Also, in many knowledge jobs, people have only a few truly high-output hours each day. The rest is email, coordination, and context-switching. Compressing that work into four days sometimes just removes low-value activity rather than real productivity.
In other jobs, it is possible to readily share tasks. If you have four employees doing similar tasks working five days a week, you could potentially have five employees working a four-day work week. You would consider this if the offer of a four-day workweek were important for attracting the right kind of talent. Of course, to make it work, employees would have to be happy with being paid for four days, not five.
When Very Long Days Make Sense
Finally, certain jobs occasionally require very long hours:
Bottleneck roles: If everything must pass through a particular individual, their availability constrains the entire system.
Labour shortages: If you only have one qualified technician, driver, or specialist, the work doesn’t vanish when their eight hours are up.
High-stakes moments: Shipping deadlines, product launches, or live operational incidents that won’t wait for tomorrow.
Whether this is sustainable depends on the person’s stamina and the organization’s ability to compensate meaningfully. More importantly, these situations should be treated as work design problems, not as heroics that become the norm by accident.
The Real Secret
The secret to worktime design is resisting the urge to generalize. There is no universal optimal workweek—only specific jobs in specific contexts.
If you treat work scheduling as an ideological issue (“short weeks are good”, “long weeks are bad”), you will make poor choices. If instead you treat it as a design question shaped by economics, workload reality, and equity, you’re far more likely to end up with arrangements that actually work—for the business and for the people.
The goal is not to pick a side in the four-day-versus-nine-day debate. The goal is to match work patterns to the realities of the work.
