In this article, we'll demystify the 9/80 work schedule, its origins, and mechanics. This guide will highlight the reasons for its implementation and considerations to ponder before adoption.
A 9/80 work schedule is an alternative work arrangement that allows employees to work 80 hours over nine days instead of the traditional ten-day, two-week schedule. This setup provides employees with a three-day weekend every other week without reducing their total work hours.
Here’s how it works:
Employees work nine hours per day from Monday to Thursday.
On Friday of the first week, they work eight hours (which is split into two four-hour periods for payroll purposes).
The second week follows the same pattern, but Friday is off.
This schedule helps businesses increase productivity, improve work-life balance, and reduce commuting costs while ensuring a full-time workload.
9/80 work schedule example:
The 9/80 work schedule typically spans two weeks, with the work hours divided as follows:
Day
Week 1
Week 2
Monday
9 hours
9 hours
Tuesday
9 hours

Wednesday
9 hours
9 hours
Thursday
9 hours
9 hours
Friday
8 hours (4+4 split)
Off
Saturday

Off
Sunday
Off
Off
Week 1: Employees work 44 hours total (40 regular + 4 hours rolling into Week 2).
Week 2: Employees work 36 hours total (making up the full 80-hour period).
This structured approach ensures compliance with overtime laws and maximises efficiency while offering employees a well-deserved break every other Friday.
Please note that this is just a sample; actual start and end times may vary based on organisational needs. And, as always, local labor laws regarding meal and rest breaks must be considered when implementing such a schedule.
Traditional 5-Day Workweek VS a 9/80 Work Schedule
The traditional 5-day workweek and the 9/80 work schedule both total 80 hours over two weeks, but they differ in how those hours are distributed. Below is a detailed comparison of these two work arrangements:

Businesses looking to improve flexibility and employee satisfaction
So which schedule is better?
The traditional 5-day workweek is better suited for companies with strict customer service needs, shift work, or industries that require constant availability.
The 9/80 work schedule is ideal for knowledge-based industries, offices, and businesses that can afford some scheduling flexibility.
Employers considering the 9/80 schedule should evaluate business needs, compliance with labor laws, and employee preferences before implementation.
Legal considerations for a 9/80 Work Schedule
Implementing a 9/80 work schedule can offer employees greater flexibility and work-life balance, but employers must carefully navigate legal requirements to avoid compliance issues. Labor laws in the U.S. and U.K. have specific regulations regarding work hours, overtime, and payroll, which must be followed when adopting this schedule.
Overtime rules and workweek definition (U.S.)
In the United States, the Fair Labor Standards Act (FLSA) governs overtime pay. Under the FLSA, employees must receive overtime pay (at least 1.5 times their regular hourly rate) for any hours worked over 40 in a defined workweek.
With a 9/80 schedule, proper payroll structuring is critical to avoid unnecessary overtime payments. Employers must redefine the workweek so it begins at the midpoint of the first Friday and ends at the same time the following Friday. This setup ensures that employees do not exceed 40 hours in a single workweek and helps avoid automatic overtime liabilities.
Example of a Proper Workweek Setup
The first four days (Monday-Thursday) total 9 hours each = 36 hours.
The first four hours of the first Friday complete the first workweek at 40 hours total.
The remaining four hours on the first Friday are part of the second workweek.
The second workweek includes Monday-Thursday (9 hours each) + 4 Friday hours = 36 hours total.
Without this proper workweek split, the 4 extra hours from the first Friday could be considered overtime, resulting in additional payroll costs.
⚠️ Caution: In California, overtime is triggered when an employee works more than 8 hours per day, even if they do not exceed 40 hours per week. This means a 9-hour workday in California could automatically result in daily overtime. Employers operating in states with daily overtime laws must check local regulations before adopting a 9/80 schedule.
Compliance with U.S. state laws
Beyond federal FLSA rules, state laws vary in how they regulate alternative work schedules:
State
Daily Overtime Rules
9/80 Considerations
California
Overtime applies after 8 hours per day
A 9/80 schedule triggers daily overtime unless an Alternative Workweek Schedule (AWS) is approved by employee vote.
New York
Overtime applies after 40 hours per week
No daily overtime, but employers must define the workweek correctly.
Texas
Follows FLSA standards
No daily overtime, proper workweek structuring required.
Illinois
Overtime applies after 40 hours per week
No daily overtime, but meal and break periods apply.
Washington
Overtime applies after 40 hours per week
No daily overtime, but extra pay rules apply for certain industries.
💡Tip: If your business operates in multiple states, it's essential to check state-specific labor laws before adopting a 9/80 schedule.
Legal requirements in the United Kingdom
In the UK, work hours are regulated by the Working Time Regulations 1998 and the Employment Rights Act 1996. Unlike the U.S., the UK does not have overtime laws requiring time-and-a-half pay, but employers must follow these key regulations:
Maximum weekly working hours
The standard legal working hours limit is 48 hours per week, averaged over 17 weeks.
A 9/80 schedule typically does not exceed this limit, but employers should monitor hours carefully.
Rest breaks & time off
Daily rest periods: Employees working over 6 hours must get at least a 20-minute break.
Rest between shifts: Employees must have at least 11 consecutive hours of rest between working days.
Weekly rest: Employees must have at least one full 24-hour period off per week or two 24-hour periods off per 14 days.
Flexible Working Rights
Employees can request flexible working arrangements, including a 9/80 schedule.
Employers must assess the request fairly and provide a business reason if denying the request.
💡Note: UK employers should ensure a 9/80 schedule does not interfere with legally mandated breaks and should offer opt-out agreements if employees voluntarily want to work additional hours.
Key considerations for payroll & HR compliance
Here are some of the key considerations for employers and managers in terms of payroll and compliance:
Accurate payroll processing
Payroll systems must be set up correctly to reflect the new workweek definition for 9/80 schedules.
Time tracking software (like Shiftbase) can help employers monitor compliance and prevent payroll errors.
Employment contracts
Employers must update employment contracts to reflect the change in work schedule.
Employees should formally agree to a 9/80 arrangement in writing to prevent disputes.
Union agreements & collective bargaining
If employees are covered by a union or collective agreement, employers must negotiate the 9/80 schedule terms with employee representatives.

Benefits and Challenges of the 9/80 Work Schedule
Implementing a 9/80 work schedule can provide both employers and employees with significant advantages, but it also comes with potential challenges. Below, we break down the key benefits and challenges to help businesses make an informed decision.
Benefits of a 9/80 work schedule
Three-day weekend every other week: Employees get a full Friday off every two weeks, improving work-life balance and allowing more time for personal activities, travel, or rest.
Increased Productivity: Employees work longer but fewer days, which can reduce distractions and increase deep focus on tasks. With fewer transitions between workdays, employees often complete projects faster.
Reduced commuting costs and time Employees commute one less day every two weeks, which means less money spent on gas, public transport, and parking. Reducing commute days also lowers stress and fatigue, leading to a more energised workforce.
Employee satisfaction and retention: A 9/80 schedule offers greater flexibility and is seen as an attractive benefit for employees. Improved work-life balance can lead to higher job satisfaction and lower turnover rates.
Better work coverage and customer support: With staggered 9/80 schedules, employers can ensure business continuity while allowing employees to take every other Friday off.This is especially useful for businesses that need extended service hours without adding extra shifts.
Lower operational costs: Companies may see reduced energy consumption in offices and facilities that close or operate with fewer staff every other Friday. Less time spent commuting also helps remote and hybrid teams optimise their workdays.
Challenges of a 9/80 work schedule
Longer workdays can lead to fatigue: Employees work 9-hour shifts, which can be mentally and physically draining. Some employees may struggle with extended focus, especially in physically demanding roles.
Increased overtime risks (U.S. Employers): If the workweek is not redefined correctly, the first Friday’s extra 4 hours may count as overtime, leading to higher labor costs. Employers in California and other states with daily overtime laws must carefully manage compliance.
Coverage issues on Fridays: If all employees take the same Friday off, it can leave gaps in coverage and affect customer service. Employers may need to stagger schedules or ensure essential staff are always available.
Scheduling conflicts in team-based work: Teams may find it difficult to schedule meetings or collaborate effectively when some employees are off on alternating Fridays. Project deadlines and cross-department coordination may require extra planning.
Potential resistance from employees: Some employees may not prefer longer workdays, especially those with childcare, eldercare, or personal commitments. Employers must gather feedback and consider offering alternative flexible work arrangements.
Legal and compliance challenges: Employers must define the workweek correctly to avoid overtime penalties. Some states/countries require formal approval or contract amendments for alternative work schedules. Unionised workplaces may need negotiation with labor representatives before implementing changes.
Implementation Best Practices for a 9/80 Work Schedule
Successfully implementing a 9/80 work schedule requires careful planning, communication, and compliance with labor laws. Below are the best practices employers should follow to ensure a smooth transition and maximise the benefits of this schedule.
Define the workweek properly to avoid overtime costs
In the U.S., the Fair Labor Standards Act (FLSA) requires employers to track workweeks accurately to avoid overtime liabilities. A common mistake when implementing a 9/80 schedule is not redefining the workweek, which can lead to unintended overtime payments.
How to properly structure the workweek:
The official workweek should start at the midpoint of the first Friday’s shift (after the first four hours).
This ensures that the first workweek ends with exactly 40 hours, preventing the extra 4 hours from triggering overtime pay.
The next workweek includes the second Friday off, totalling 36 hours, which balances out over two weeks.
✔ Tip: Use time-tracking software (like Shiftbase) to monitor hours and ensure compliance.
Communicate clearly with employees
Change can be challenging, and employees may have concerns about longer workdays or how the schedule will impact their routines. Employers should:
Hold informational meetings to explain the 9/80 schedule and its benefits.
The 9/80 work schedule may seem like a magical solution to the often tricky puzzle of work-life balance. Indeed, it offers a raft of benefits including increased employee productivity, improved work-life balance, and the potential for reduced commute times.
However, like any significant change, it must be approached with careful consideration of legal compliance, employee preferences, and business operations.

Frequently Asked Questions
A 9/80 work schedule is designed for full-time employees working 80 hours over two weeks, so it may not be directly applicable to part-time employees. However, part-time employees can still benefit from flexible scheduling in workplaces that implement a 9/80 structure. Here’s how:
✔ Customisable Schedules – Employers can create alternative part-time versions of a 9/80 schedule based on employee needs. For example:
A part-time employee working 20-30 hours per week could follow a compressed schedule, such as three 10-hour shifts per week instead of five shorter shifts.
Some part-time employees could work a modified version of the 9/80 schedule, such as three 9-hour days and one 4-hour day per week.
✔ Payroll and Benefits Considerations – Part-time employees typically do not meet the 40-hour weekly threshold for overtime rules in the U.S. However, if a part-time employee works more than 40 hours in a single workweek, they may still be eligible for overtime pay.
✔ Impact on Work-Life Balance – Part-time employees may appreciate longer shifts with additional days off, but some may prefer shorter, more consistent shifts instead. Employers should offer flexible options that align with business needs and employee preferences.
✔ Company Policy and Role-Specific Adjustments – Not all roles can support compressed work schedules. Employers should evaluate job responsibilities and ensure part-time employees can maintain productivity without disrupting team workflows.
The 9/80 work schedule is popular in industries that benefit from increased efficiency, longer workdays, and fewer transition times between shifts. The most common industries that implement this schedule include:
Government and Public Sector: Many federal, state, and local government agencies use 9/80 schedules to increase efficiency while providing employees with flexibility and extended weekends.
Engineering and Construction: Engineering firms and construction companies use 9/80 schedules to maximise daylight hours and reduce daily setup and teardown times. Employees benefit from fewer commutes and longer focused work periods.
Manufacturing and Industrial Work: Some factories and production plants adopt 9/80 schedules to improve workflow efficiency and reduce shift transitions. Helps minimise downtime in production and allows better maintenance scheduling.
Aerospace and Defence: Many aerospace, defence, and high-tech manufacturing companies (such as NASA, Boeing, and Lockheed Martin) use a 9/80 schedule to support project-based work that requires extended hours. Employees get extra flexibility while maintaining strict project deadlines.
Technology and Software Development: Some tech companies adopt 9/80 schedules to provide engineers and developers with focused work periods. Helps reduce burnout while maintaining high levels of innovation and productivity.
Healthcare (Selective Roles): While traditional healthcare roles (e.g., nurses, doctors) follow shift-based models, some administrative healthcare employees benefit from a 9/80 workweek. Common for healthcare IT, research, and hospital administration roles.
