4 Day Work Week Guide (Models, FLSA Rules, Checklist)

A 4 day work week is a schedule where full-time employees work four days instead of five. It comes in three main forms: 32 hours a week at the same pay, a compressed week of four 10-hour days, or a 9/80 schedule with every other Friday off. Each one changes your overtime math differently, so pick the model before you announce anything.

What Is a 4 Day Work Week?

A four-day work week is any work schedule that shrinks the standard workweek from five work days to four. What changes from one company to the next is what happens to the hours and the pay.

The version most people mean is the 100-80-100 model: 100% of pay for 80% of the time, in exchange for keeping 100% of output. The nonprofit 4 Day Week Global promotes this model, and it sits at the center of the 4-day work week movement.

If you manage a team, treat it as a policy decision like the others in our workplace management guides. Define the hours, the pay, the coverage and the exit plan first.

A four-day week is also different from flexible work. Hybrid and remote setups change where people work; a shorter work week changes how many days they work. Many teams combine both, and our look at remote work in 2026 covers the location side.

How Does a Four-Day Work Week Schedule Work?

There are four common ways to build a 4-day week schedule. They look alike on a calendar and behave very differently on payroll.

1. The 32-hour work week (reduced hours)

Employees work 32 hours, usually four 8-hour days, for the same salary. It is the only model that gives people shorter hours without making each workday longer.

It costs you the most if output drops, because you pay a five-day salary for four days of work hours. To match the old output, each hour has to produce about 25% more, since 40 divided by 32 is 1.25. Fewer hours only pay off when productivity per hour rises by that much.

It fits teams where the fifth day was going to meetings, status updates and context switching.

2. The compressed week (four 10-hour days)

Employees fit a 40-hour week in four days of 10 hours per day, often Monday to Thursday. Payroll does not change, and everyone gets an extra day off.

The catch is the 10-hour day. Long shifts are tiring, school pickups get harder, and the last two hours tend to be the least focused. A compressed work week moves the workload around. It does not shrink it.

3. The 9/80 schedule (every other Friday off)

Employees work 80 hours over two weeks: eight 9-hour days, one 8-hour day and one day off, usually every other Friday. It suits office teams that want a regular extra day without 10-hour shifts.

4. Staggered days off

Half the team takes Monday off and half takes Friday, so the business stays open five days a week. Support and sales teams use it to protect customer satisfaction. It needs a shared calendar and a written handoff rule.

Does a 4-Day Workweek Improve Productivity?

It can, when the hours you remove were not producing much. The Wikipedia overview of the four-day workweek collects global trials, from Iceland's public sector to Microsoft Japan's 2019 summer experiment, where participating companies reported increased job satisfaction and less burnout.

Read those results with care. The companies in a workweek pilot chose to join and wanted it to work. Your result depends on your work design and work environment, not on the calendar.

Productivity tends to hold up in shorter workweeks for concrete reasons:

• Fewer meetings. Cutting a weekly 60-minute status meeting to a 15-minute written update gives back time without touching real output.
• Protected focus blocks. A rule like "no meetings before noon on Tuesday and Wednesday" gives people two long stretches of deep work.
• Sharper priorities. With Friday gone, low-value work gets dropped instead of rescheduled.
• Fewer partial-day absences. Doctor, bank and school appointments move to the day of rest instead of breaking up a workday.

Job performance in some roles is measured in finished work; in others, in hours covered. A developer's output survives a shorter workweek more easily than a receptionist's, because nobody needs to sit at the developer's desk on Friday.

Work ability counts too. Someone recovering from illness or caring for a parent may manage four days a week well and five days badly, and a four-day option can keep that person on staff.

If your team already struggles to prioritize, fix that before you cut a day. These time management skills with examples make a good starting checklist.

What Are the Cons of a Four-Day Work Week?

The cons of a four-day week fall on coverage, cost and fairness. Put them in your plan instead of discovering them in month two.

• Coverage gaps. A client who emails on Friday and hears back on Monday assumes nobody is there.
• Long-day fatigue. Four 10-hour days can raise burnout for people who were already stretched.
• Uneven access. Office staff get Fridays off while warehouse or support staff do not, and resentment follows unless every group gets some version.
• Hidden overtime. If the work does not fit, people answer email on their day off, and for non-exempt staff that time is paid time.
• Outside partners. Vendors and customers still keep a five-day week, so someone has to own Friday.

Cut the meetings before you cut the day: a four-day week only works when the fifth day's waste goes first.

How Do US Overtime Rules Apply to a 4-Day Work Week?

As of November 2026, the federal Fair Labor Standards Act overtime rules generally require 1.5 times the regular rate for non-exempt employees who work more than 40 hours in a workweek. Federal law counts by the week, not by the day. This is general information, so check your state law or an employment lawyer before you change schedules.

Compressed weeks and daily overtime

Under the federal weekly rule, four 10-hour days total 40 hours and owe no overtime. Some states also count by the day. California generally requires overtime after 8 hours in a workday, so each 10-hour day carries 2 overtime hours, or 8 a week per employee.

As of November 2026, California lets employers avoid that daily overtime through an alternative workweek schedule, adopted by a secret-ballot vote of at least two-thirds of the affected employees and reported to the state. Skip the vote and the daily overtime is still owed.

The 9/80 workweek trap

Run a 9/80 schedule on a Monday-to-Sunday workweek and you get one week of 44 hours (four 9-hour days plus an 8-hour Friday) and one week of 36. The 44-hour week owes 4 hours of overtime to every non-exempt employee on it.

The usual fix is to start the official workweek at the midpoint of the 8-hour Friday. Four hours of that Friday fall in each workweek, so both workweeks total exactly 40. Set it in writing before the schedule starts, and do not switch it back and forth.

Pay on a 32-hour week

For hourly staff, a four-day week with no loss of pay means a higher hourly rate. Someone earning $20 an hour for 40 hours ($800 a week) needs $25 an hour to earn $800 in 32 hours. Any overtime is then 1.5 times $25, which is $37.50.

For salaried exempt staff, cutting pay along with hours can cost them exempt status if the salary falls below the federal or state salary threshold. The Labor Department overtime page linked above lists the federal figure, so check it before you offer an 80% salary option.

How Do You Implement a Four-Day Week? (7-Step Checklist)

Implementing a four-day week is mostly preparation. You do not need a business school case study; you need a calendar, a payroll check and three months of numbers. Work through these steps in order.

1. Pick the model and the day. Choose 32 hours, 4x10, 9/80 or staggered, and decide whether everyone shares the same extra day.
2. Map coverage. List every outside commitment (customer hours, on-call, vendor deadlines, payroll runs) and name who covers each one on each day.
3. Cut work before you cut time. Audit recurring meetings and reports. Delete, shorten or move to async anything without a clear owner and decision.
4. Choose 3 to 5 metrics and baseline them. Pull the last three months of the same numbers so you have something to compare against.
5. Write the policy. Use the sample wording below and cover hours, pay, holidays, PTO, eligibility and the end date.
6. Check the legal side. Weekly and daily overtime, exempt salary levels and any union agreement.
7. Announce a pilot, not a perk. Give it a start date, an end date and a review meeting.

When you announce the new work schedule, say what stays the same, what changes and how the team will know if it worked. For example: "From March 2 to May 29 we are piloting a four-day week. Pay and benefits do not change. In June we will review customer response times and delivery dates and decide together whether to keep it."

Tie the change to what your people value. If you are not sure what drives them, these motivators at work give you questions to ask before the pilot starts.

What Should a 4-Day Work Week Policy Say?

Paste these clauses into your handbook draft and fill in the brackets. Have an employment lawyer review the final version.

1. Schedule. "Full-time employees in [teams] work [Monday to Thursday], [8 / 10] hours a day. Core hours are [9:00 to 15:00]."
2. Pay and benefits. "Base pay, benefits and PTO accrual stay at full-time levels during the pilot."
3. Holidays. "A company holiday on a scheduled workday is paid at [8 / 10] hours. A holiday on the regular day off [is not replaced / becomes a floating day]."
4. PTO. "One day of PTO equals one scheduled workday of [8 / 10] hours."
5. Coverage. "Each team keeps [one person] available on [Friday] on a rotation published two weeks ahead."
6. Time records. "Non-exempt employees record all time worked, including on the day off, and are paid overtime as the law requires."
7. Review. "This pilot runs from [date] to [date]. The company may change or end it with [30] days' notice."

How Long Should a 4-Day Work Week Trial Run?

Run a 4-day work week trial for at least three months. The first weeks are noisy: people are adjusting, and the novelty lifts mood. Six months covers a busy season and shows whether the gains from shorter working time last.

Measure the same things before and during the pilot, so you can see how the work gets done and not only how people feel:

• Output per team: tickets closed, projects delivered on time, sales calls booked.
• Customer response time: median hours to first reply, checked separately for Fridays.
• Customer satisfaction: the survey score you already collect, so no new tool is needed.
• Overtime and day-off activity: paid overtime hours and messages sent on the day off.
• Workload and burnout: a monthly three-question pulse survey on workload, energy and focus.
• Retention: resignations and applicants per open role, compared with the same months last year.

Decide in advance what result changes the plan. For example: "If Friday response time rises by more than one business day, we switch to staggered days off before continuing."

Is a 4 Day Work Week Right for Your Team?

A four day work week fits best when output is measurable, work can be planned a week ahead, and you have enough people to cover every day you promise customers.

It is a harder fit for roles paid to be present: front desk, retail floor, live support with fixed hours. Those teams can still get shorter weeks through staggered days, a 9/80 schedule or summer Fridays.

If you are an employee who wants one, propose a 90-day trial for yourself with output measures attached. Try: "My projects will still ship on the same dates, and you can check them in our tracker every Thursday."

4 Day Work Week FAQ

What is the 3-3-3 rule at work?

The 3-3-3 rule is a daily planning method: spend 3 hours on your most important project, finish 3 shorter urgent tasks, and handle 3 maintenance tasks such as email or admin. It pairs well with a four-day week because it makes you name the work that matters each day.

Which countries have a four-day work week?

No country has made the four-day week the legal standard for all workers as of November 2026. Belgium lets many employees request a full-time week compressed into four days, and Iceland, the UK, Spain, Portugal, Japan and many other countries have hosted 4-day workweeks as trials, as the Wikipedia entry linked above records.

Can you work 4 days a week and still be full-time?

Generally yes. A 4x10 schedule is 40 hours per week, the same as a five-day week. Whether 32 hours counts as full-time for pay and benefits depends on your employer's policy and benefit plan rules, so ask HR to confirm it in writing.

Is a compressed workweek the same as a shorter workweek?

Not always. A compressed workweek keeps 40 hours in fewer days, while a reduced-hours week cuts the total to about 32. Both get called four-day weeks, so say which one you mean.

Do employees work 32 hours on a 4-day week?

In the reduced-hours model, yes: employees work 32 hours, four 8-hour days, usually at the same salary. In the compressed model they work 40 hours, and in a 9/80 schedule they average 40.

What is a 9/80 work schedule?

A 9/80 schedule is 80 hours over two weeks with one weekday off, usually every other Friday. Employees work eight 9-hour days and one 8-hour day, and the official workweek should start halfway through that 8-hour day to avoid a 44-hour week.

How do holidays and PTO work on a four-day week?

Your policy decides, so write it down. A clean rule is that one PTO day equals one scheduled workday, and a holiday that falls on the regular day off is not replaced unless the policy says otherwise.
