Alternative work schedules are any regular working pattern other than five eight hour days at set times. Most of them change one of three things: when the hours fall, how many days hold them, or how many hours there are in total. That choice decides the bill. An employee in Texas who moves to four 10 hour days works the same 40 hours and costs the same as before. The same employee in California, paid $30 an hour with no workplace vote behind the schedule, costs $120 more a week, or $6,240 more a year.
Coverage decides whether alternative work schedules survive. The US Social Security Administration told staff in 2026 that it was ending 4/10 and 5/4/9 schedules because they thin out staffing on days off, and Utah dropped a statewide four day week in 2011 after complaints about service and thin savings. This guide covers 10 alternative work schedule examples and the overtime rules in the US, Canada, the UK and Belgium. It also reviews the evidence on the four day week and shows how to test a schedule before you commit to it.

What is an alternative work schedule?
An alternative work schedule is an agreed, repeating pattern of hours that departs from the standard five day week while the job itself stays the same. A one off shift swap does not count, and neither does an ordinary full time or part time contract, although some long lists of alternative work schedules include both.
The phrase means different things depending on who uses it:
- US federal employment. Here it is a legal category with two branches. The OPM handbook covers compressed schedules, which fit the basic work requirement into fewer than 10 workdays per pay period, and flexible schedules, which combine core hours with hours the employee chooses.
- California. An “alternative workweek schedule” is a legal status that a work unit earns through a secret ballot election. Without it, a 10 hour day pays daily overtime.
- UK and general HR use. The wider term is flexible working, and Acas lists compressed hours, staggered hours, job sharing and annualised hours under it.
10 alternative work schedule examples
These alternative work schedule examples are grouped by what they change. The last column names the first thing to check, because it usually decides whether the pattern works for your team.
| Schedule | Pattern | Average weekly hours | What changes | Check first |
|---|---|---|---|---|
| 4/10 work schedule | Four 10 hour days | 40 | Number of days | Daily overtime rules, cover on the fifth day |
| 5/4/9, also called 9/80 | Eight 9 hour days, one 8 hour day, one day off every two weeks | 40 | Number of days | Where the workweek starts and ends |
| Three 12s | Three 12 hour days | 36 | Days and total hours | Fatigue, whether 36 hours counts as full time for benefits |
| Reduced four day week | Four days of about 8 hours, pay kept | About 32 | Total hours | What work stops so the output holds |
| Flextime | Core hours plus a chosen start and finish | 40 | Timing | Overlap for meetings and handovers |
| Staggered hours | Set starts that differ by person, such as 7am to 4pm and 9am to 6pm | 40 | Timing | Who covers the first and last hour |
| Job sharing | Two people split one job, with a handover | 40 across two people | Who does the hours | Overlap time and per person benefit costs |
| Annualised hours | A yearly total, such as 1,500 hours, with busy and quiet seasons | Varies | Timing across the year | Weekly overtime law, which can rule it out in the US |
| Rotating 12 hour shifts | Crews rotate, such as 4-3-3-4 | 42 | Days and timing | Overtime in the long week, rest between shifts |
| Results only work environment (ROWE) | No set hours, judged on results | Not set | Whether hours matter at all | Whether results can be measured, overtime for nonexempt staff |
The weekly figures are simple arithmetic from each pattern. The 7am to 4pm example and the 1,500 hour year come from Acas, and the 5/4/9 pattern from OPM.
What the number codes mean
- 5/4/9 work schedule. Over two weeks, a full time employee works eight 9 hour days and one 8 hour day, then takes the tenth day off, for 80 hours. It is the same pattern as the 9/80, which has its own guide.
- 5-2-5-3 work schedule. Five shifts on, two days off, five shifts on, three days off, in a 15 day cycle. That is 10 shifts in 15 days, so with 8 hour shifts the average is about 37 hours a week.
- 4-3-3-4 work schedule. Four days on, three off, three on, four off, in a 14 day rotation of 12 hour shifts. One week holds 48 hours and the next 36. Under US federal law that means 8 overtime hours in the long week, even though the average is 42.
Compressed work week: same hours, fewer days
A compressed work week keeps the weekly total and packs it into fewer days. The 4/10 work schedule gives a three day weekend every week, and the 5/4/9 gives one every two weeks. At the extreme, the OPM handbook describes a three day federal week of 13 hours and 20 minutes a day.
The trade is a longer day for a shorter week, and that trade has a limit. One review of shiftwork research puts injury risk 13% higher on 10 hour shifts and 28% higher on 12 hour shifts than on 8 hour shifts. In our view, a compressed workweek suits desk work and projects with long stretches of focus better than work around machinery, vehicles or patients, where a tired tenth hour has real consequences.
Two practical details are easy to miss in compressed work schedule policies:
- Leave has to run in hours, not days. UK law gives 5.6 weeks of paid holiday, which is 28 days on a five day week and 22.4 days on a four day week (4 x 5.6). At 8 hours and 10 hours a day, both come to 224 hours. A policy that counts one day of leave as 8 hours leaves a 4/10 employee 2 hours short every time.
- Public holidays need a rule. A full time US federal employee on a compressed schedule is paid for the hours of that day’s schedule, so 10 hours on a 4/10, and a holiday that lands on a day off moves to another workday, as OPM sets out. Private employers can choose differently, but they should choose before the first holiday. Our holiday pay guide covers the overtime side.
Four day work week: compressed or reduced?
“Four day week” describes two different things, and arguments about it often mix them up. A compressed four day week keeps the hours. A reduced four day week cuts them, often to around 32, and keeps the pay. The first moves the same work around. The second only works if some of the work disappears.
Belgium shows the compressed work week in law. An employee can make a written request to fit the full week into four days, which means four 9.5 hour days on a 38 hour week. The agreement lasts up to six months and can be renewed, and the employer can refuse with written reasons within one month.
The studies we found test the reduced version:
- Six countries, 2025 paper. A Nature Human Behaviour study of 2,896 employees at 141 organizations in Australia, Canada, Ireland, New Zealand, the UK and the US found better burnout, job satisfaction, mental health and physical health after a six month trial with no pay cut. The pattern did not appear in 12 control companies. Organizations reworked how they operated before the trial began.
- UK pilot, 2022. Of the 61 companies and about 2,900 workers, 56 companies kept the policy afterwards and 18 made it permanent. Staff departures fell 57% over the trial and revenue rose 1.4% on average, which the report describes as broadly flat.
- US adoption. In the American Psychological Association survey, 22% of respondents said their employer offered a 4 day work week in 2024, up from 14% in 2022.
Pros and cons of a 4 day work week
The pros and cons of a 4 day work week depend on which version you mean, so this table separates them.
| Factor | Compressed (same hours) | Reduced (fewer hours, same pay) |
|---|---|---|
| Main benefit | A full extra day off and one fewer commute a week | Less burnout and fewer departures in the trials above |
| Daily load | Longer days, with fatigue late in the shift | Normal days, with less room for low value work |
| Payroll cost | Flat, unless daily overtime applies | Flat only if output holds, otherwise overtime or extra hires |
| Client cover | A gap on the day off unless days off are split | The same gap, with fewer total hours to fill it |
| Hardest for | People who already work late, who may stretch 10 hours into 12 | Fast paced hourly work with little idle time to remove, such as manufacturing |
Overtime rules: the same 40 hours, different bills
Alternative work schedules change overtime because overtime law counts hours per day in some places and per week in others. A 4/10 week is free of overtime where only the week matters, and it creates 8 overtime hours where the day matters and no exception applies. Here is the California example from the top of this guide, for a nonexempt employee.
The sum is an illustration that assumes 52 full weeks with no leave. For a team of 10 it reaches $62,400, for the same 40 hours per person. The next table shows where that exposure applies. This is general information, not legal advice, and sector rules or union agreements can differ.
| Where | Is a 10 hour day overtime? | What makes a 4/10 work |
|---|---|---|
| US federal law (private employers) | No. Overtime starts after 40 hours in a workweek, and averaging across weeks is not allowed | Nothing extra, unless a state adds a daily rule |
| California | Yes, past 8 hours, and double time past 12 | An adopted alternative workweek of up to 10 hours a day within 40 a week |
| Alaska | Yes, past 8 hours, for employers with 4 or more employees | A voluntary Flexible Work Hour Plan, which covers hours up to 10 a day |
| Nevada | Below a pay threshold, yes. See our Nevada guide | A mutually agreed schedule of four 10 hour days |
| US federal employees | No, when 10 hours is the compressed schedule | An agency compressed schedule; overtime is time beyond it |
| Ontario | No daily overtime, unless a contract says so. Overtime starts after 44 hours a week | Nothing extra. Averaging over up to 4 weeks is possible by agreement |
| British Columbia | Yes, past 8 hours | An averaging agreement signed before the start date, up to 12 hours a day and 40 a week on average |
| UK | No legal overtime pay, though average pay cannot fall below the National Minimum Wage | Keep 11 hours of rest between days and 48 hours a week on average |
| Belgium | The four day option sets a 9.5 hour day on a 38 hour week | A written agreement of up to six months, renewable |
California alternative work schedule: what the vote requires
A California alternative work schedule is valid only if the employer follows the wage order election procedure. Skipping the written disclosure makes the election void, and daily overtime then applies. The steps below follow the wage order text, and our California overtime guide covers the rest of the state’s rules.
- Put the proposal in writing, with a regular number of workdays and hours. The employer can offer one schedule or a menu.
- Disclose in writing the effect on wages, hours and benefits, and hold a noticed meeting at least 14 days before the vote.
- Hold a secret ballot during working hours at the worksite. Approval takes two thirds of the affected employees in the work unit.
- Report the result to the state within 30 days, and wait at least 30 days after the result before requiring the new hours.
- Keep the hourly rate. An employer cannot cut it because of the election.
One trap comes after the vote: hours beyond the agreed schedule are overtime, and if the employer sends someone home on a shorter day than scheduled, that day falls back to overtime past 8 hours. Employees can also repeal the schedule, with a petition from one third of them and a two thirds vote.
Why employers end alternative work schedules
The three cases below ended for different reasons: coverage, savings that did not arrive, and a leadership decision about presence.
| Case | What was promised or found | Why it ended |
|---|---|---|
| US Social Security Administration, 2026 | 4/10 and 5/4/9 schedules, covered by a union agreement | The agency said they reduce staffing on days off and that “a consistent five-day workweek” serves the public better. The union says few employees use them and has filed a national grievance |
| State of Utah, 2008 to 2011 | About 13,000 of 17,000 full time state employees on four 10 hour days, with $3 million a year expected from energy alone | The legislative audit found energy savings of about $502,000 and total savings under $1 million, and warned that a 1% productivity drop would cost far more. Service complaints added to the case |
| Best Buy ROWE, ended 2013 | A study of 775 headquarters staff found ROWE cut the rate of leaving by 45.5% over eight months | New leadership wanted people in the office during a turnaround, an “all hands on deck” approach |
The Social Security decision is not isolated. Federal News Network reports that Homeland Security and the IRS ended alternative work schedules in 2025, though Homeland Security later let its cybersecurity agency bring flexible schedules back to help with hiring. In a reader poll of 592 federal employees, almost 78% said their agency still offered alternative work schedules. That poll is not a random sample.
Our take: Utah and Best Buy suggest that turnover and cost figures may not protect a schedule on their own. Name the service level you will hold on the day off, and sell the schedule to leadership on that number.
Which alternative work schedule fits your problem
Alternative work schedules can fail when the pattern comes first, so start from the problem. These picks are our recommendations, based on the rules and evidence above.
| Your situation | Pick | Avoid |
|---|---|---|
| Long commutes or crowded start times | Staggered hours | Changing the pattern for everyone at once |
| Staff with school runs or care duties | Flextime with core hours | 10 hour days, which clash with fixed pickups |
| Project team with long focus work and few walk in clients | 5/4/9 first, then 4/10 if it holds | The same day off for the whole team |
| Burnout on a knowledge team | Reduced four day week, after cutting meetings and low value work | A compressed work week, which keeps the load |
| Service open five days a week | Staggered hours, or split days off across the team | A single shared day off |
| Round the clock operations | Rotating shifts with a fatigue review | Adding overtime to 12 hour shifts |
| Experienced person who wants fewer hours | Job sharing with paid overlap | Splitting tasks with no handover time |
| Strong seasonal peaks | Annualised hours in the UK; seasonal staffing in the US | Unmanaged overtime through the peak |

How to trial alternative work schedules
A trial of alternative work schedules protects both sides: employees get a fair test, and the employer gets a way back. Six months matches the research above and the renewal term in Belgium.
-
Name the problem and record a baseline.
Pull at least eight weeks of hours, overtime, late work, absence and departures, so you have something to compare against.
-
Check the rules before you announce anything.
Confirm daily overtime, rest periods and any election, plan or agreement your location requires. California and British Columbia both need the paperwork in place before the new hours start.
-
Write the coverage rule.
State who answers clients on each day off, how urgent work reaches them, and which day each person takes.
-
Set leave and holidays in hours.
Convert balances, decide how public holidays are paid, and tell people what happens to accrued time.
-
Set an end date and a test.
Agree that the schedule ends unless the numbers hold. Choose two or three measures, such as overtime hours and response time, and decide the pass mark in advance.
-
Review and decide.
Compare the trial with the baseline, ask the team what broke, and then keep, adjust or drop the schedule. Watch for hidden overtime, because a four day week that spills into the fifth day has not worked.
How to track alternative work schedules in actiTIME
Utah’s savings claims fell apart once auditors checked them, so a trial needs numbers for hours, overtime and output. actiTIME is project time tracking software, and it records this data as a side effect of normal timesheets.
- Schedules by person. Work schedules can be company wide or per user, so a 4/10 employee and a five day colleague sit in one account.
- Exact hours. People log hours in a weekly timesheet, or as start and stop times in Calendar View if the day is split or staggered.
- Overtime against the schedule. With Overtime Registration on, overtime is calculated automatically or entered by hand, per user, at its own rate.
- Trial reports. The Time Balance and Overtime Report compares work time with scheduled hours, the Cost of Work Report shows staff cost including overtime and leave, and the Profit/Loss Report shows what happened to project margins.
- Leave in the same place. Leave time is logged in hours in the timesheet, which fits the rule above.
Overtime Registration and Type of Schedule are not in the free version, so run a test on the 30 day full featured trial.
We reduced payroll processing to 45 minutes per week
actiTIME is very robust, integrated well into your business process, and most important, helps you focus on your business instead of monkeying around with technology. actiTIME has reduced our payroll processing from 4-6 hours per week to 45 minutes per week.
FAQ
Is an alternate work schedule the same as an alternative work schedule?
Yes. People use alternate work schedules and alternative work schedules for the same thing, and OPM’s own handbook appears under both names. The word only matters in California, where “alternative workweek schedule” is the legal term for a schedule adopted by election.
Can an employee ask for an alternative work schedule?
Anyone can ask, but the employer’s duty varies. In the US, the federal overtime law does not address flexible schedules and leaves them to agreement, although a modified work schedule can be a required accommodation for a disability, absent undue hardship. In the UK, employees can request flexible working from their first day, and a stricter reasonableness test for refusals is due in 2027.
Can an employer move staff back to a five day week?
Usually, unless a contract, union agreement or election ties the schedule down, and that is where disputes start. The Social Security union’s grievance rests on its contract. In California, the repeal route in the wage order runs through employees. In the UK, an approved flexible working request has to be confirmed within 28 days, so agree any trial period in writing at the start. Take local advice before you reverse a schedule.
Fix the hours problem, then choose the schedule
Alternative work schedules work best when they solve one named problem, fit the local overtime rules and keep the service covered. Whichever you try, you need clean data to judge it. You can start a free trial of actiTIME with all features for 30 days, stay on the permanent free version for up to 3 users, or move to the online version from $5 per user per month.
