Ask a team about to start a four-day week what will change, and most will talk about the day off. Ask a team that has made it work a year later, and they will talk about the work that disappeared.
That difference is the whole game.
At Day5Group, we help organisations transition to a four-day week. Our consistent advice is unfashionable: do not start by deleting a day. Start by deleting work. A shorter week is funded by tasks that stop, shrink, move or automate. If nothing stops, staff pay for the day with intensity, and the pilot will feel like a faster treadmill.
Why the calendar is the wrong place to start
A calendar change is visible and easy to announce. Work deletion is slower and requires judgement. So organisations announce the calendar and postpone the judgement. For a few weeks, goodwill carries the gap. Then the unchanged reports, approvals and meetings reassert themselves inside four days, evenings absorb the overflow, and leaders conclude that “our work is different”.
The early cases point the other way. At Perpetual Guardian in 2018, teams were invited to challenge how they used time as part of the bargain. In Iceland’s public-sector trials, workplaces reorganised routines and meeting habits while protecting service. In both, time fell because methods changed. The day off was the result, not the method.
Building a stop-doing list that holds
Make it concrete. “Be more efficient” is not an item. “Monthly operations deck produced by three people for a meeting that makes no decision” is an item.
Work through five buckets with each team:
- Stop: reports nobody acts on, duplicate status meetings, approvals that have never changed an outcome.
- Shrink: meetings that halve in length or frequency, reports that become a one-page dashboard, reviews that move from everyone to the accountable few.
- Automate: data entry, scheduling, status chasing and document handling that software already does well.
- Delegate or defer: work that belongs at a different level, or can wait for a quieter cycle without customer harm.
- Protect: the small set of activities that create real customer value. These get more focus, not less.
For each item, name an owner and a date. A list without owners is a wish.
How much do you need to find?
The arithmetic is sobering and clarifying. A move from 40 hours to 32 requires releasing about eight hours of activity per person each week, unless output definitions change. You rarely find all eight in the first pass, and part of the gap closes through better focus and fewer interruptions. But if your list frees an hour and your plan needs eight, you do not have a plan yet.
That is why the stop-doing exercise belongs before the pilot announcement. It is a feasibility test disguised as housekeeping.
Who gets to stop work?
The list fails when only junior staff may propose and only senior staff may refuse. Leaders must put their own demands on the table: the standing meeting they like, the report they read out of habit. Staff watch which items survive. If the chief executive’s pet routine is untouchable while team-level changes are mandatory, the pilot’s politics are settled before it starts.
Give teams a simple rule: any recurring activity can be challenged if the challenger names the decision or customer outcome it serves. If nobody can name one, it goes.
Protect the gains during the pilot
Work creeps back. New projects arrive, a client asks for a familiar report, a meeting returns “just for this month”. Counter it with three habits:
- Review the stop-doing list monthly, in the pilot meeting, with the same seriousness as the results dashboard.
- Require a “what stops?” question for every new recurring commitment.
- Track actual hours worked. If hours are not falling, the list is theatre. Say so early and fix it while trust is intact.
A practical first step
This week, ask each team for just three items: one to stop, one to shrink, one to automate. Cost them in hours. Add the numbers up in public.
You will learn whether your organisation can delete work, which is the skill a four-day week actually tests. If the answer is yes, you have the raw material for a pilot. If the answer is not yet, you have found the work to do before anyone mentions Friday.
