This pilot reframes productivity around results rather than hours at a desk. Hari recounts Andrew Barnes offering employees a four-day week at the same pay for a three-month test. Preparation forced the company to examine interruptions and work design; one simple practice used a visible white flag to signal a need for uninterrupted focus. The organization then compared performance and wellbeing with its earlier five-day pattern. Hari reports that the studied company produced more in four days, while stress and social-media use at work fell. Those results are claims relayed in the episode and should not be treated as a guarantee for every workplace. A responsible pilot preserves pay, defines baseline measures and coverage, involves the team in redesign, monitors workload intensity and service quality, and makes continuation conditional on evidence.
Origin
Hari tells how New Zealand businessman Andrew Barnes used a three-month equal-pay trial after questioning how much of an eight-hour day employees spent concentrating.
Core principles
- 01Measure output rather than desk time
- 02Keep pay constant during the test
- 03Prepare teams to protect concentration
- 04Evaluate productivity and wellbeing together
- 05Treat the change as a bounded experiment first
How to run it
- 1
Measure the baseline
Record current output, service quality, working hours, stress, absence, and coverage before changing the schedule.
Pro tip Choose measures that reflect real value rather than visible activity.
Watch out A weak baseline makes the result difficult to interpret.
- 2
Set the contract
Define the shorter schedule, keep pay unchanged, set the pilot duration, and state the outcome and safety conditions for continuation.
Pro tip Make clear that the test is not a hidden pay cut or automatic workload compression.
Watch out Essential coverage and legal obligations must be preserved.
- 3
Redesign the work
Ask employees to remove low-value meetings, reduce avoidable interruptions, and protect concentration while maintaining required collaboration.
Pro tip Use a visible signal for temporary focus periods where appropriate.
Watch out Do not shift unpaid work into the nominal day off.
- 4
Run the pilot
Operate the new schedule for the fixed period and monitor output, wellbeing, customer impact, workload intensity, and exceptions.
Pro tip Collect employee and customer evidence as well as operational metrics.
Watch out Stop or adapt the test if safety, service, or health deteriorates.
- 5
Compare and decide
Compare the pilot with the baseline and decide whether to continue, modify, or end it. Document trade-offs rather than selecting only favorable measures.
Pro tip Check whether gains came from sustainable focus or temporary sprinting.
Watch out The episode's reported cases do not establish that every organization will obtain the same result.
In the wild
Hari describes Barnes announcing a three-month move from five days to four at the same pay. Employees prepared productivity changes, including a desk signal for uninterrupted work, and the trial was studied by University of Auckland researcher Helen Delaney.
→ Hari reports higher output alongside lower stress and less social-media use at work.
Common mistakes
Cutting pay with the hours
The example's test kept compensation constant, making it a productivity and work-design experiment rather than a reduced-pay arrangement.
Skipping preparation
The team needs to remove waste and protect focus before expecting fewer scheduled hours to preserve output.
Hiding workload compression
A nominally shorter week is not a success if employees complete the same hours unpaid or sustain harmful intensity.
Is it for you?
Best for
Organizations able to measure outcomes and run a fair, bounded schedule experiment with employee participation.
Not ideal for
Organizations that cannot safely maintain essential coverage or that plan to compress the same workload into harmful intensity.
