The 9/80 Work Schedule Explained

What is a 9/80 work schedule ? 

Under a 9/80 work schedule, employees work 80 hours over 9 days instead of 10. Employees benefit by earning an extra day off every two weeks, while employers must more carefully manage coverage, team attendance, overtime, and scheduling.

How does the 9/80 work schedule work?

The basic idea is simple: employees work longer days so they can complete 80 scheduled hours across 9 working days instead of 10. 

One common example looks like this:  

The 44- and 36-hour totals refer to a calendar week. An employer may divide scheduled work hours differently for overtime purposes within their defined workweek. 

How the 9/80 schedule fits into a workweek 

A 9/80 schedule does not show a consistent number of working hours each week. One week may show 44 hours of work, while the following week may show only 36 hours. The employer can define additional details about the workweek to determine how much of the 8 hours worked on Friday remains in the first workweek. For example, a workweek could run from Friday at noon to Friday at noon the following week.

In this case, the first workweek would be 40 hours, consisting of 4 hours of work on Friday, plus 9 hours of work on Monday, Tuesday, Wednesday, and Thursday. The second workweek would be 40 hours, consisting of 9 hours each day from Monday through Thursday and 4 hours on Friday morning.

A 9/80 schedule does not remove the requirement to pay overtime when an employee works more than 40 hours in a workweek. Managers can use an employee overtime hours tracker to monitor overtime hours. 

The U.S. Department of Labor explains that hours generally cannot be averaged across two or more weeks when determining overtime.

The scheduled Friday off alternates every other week, creating a three-day weekend in the week when Friday is off. 

This is one example of a compressed work schedule. The U.S. Office of Personnel Management defines compressed work schedules as alternative work schedules in which employees work a fixed number of hours in fewer days compared to the typical workweek. U.S. Office of Personnel Management: Alternative Work Schedules

There are several variations of a 9/80 schedule, and the additional day off does not have to be on a Friday.

For each employee, document scheduled days and hours, start and end times, regular days off with any recurring patterns, holidays, paid time off, and schedule change rules.

The 9/80 work schedule and flexible working hours

Flexible working hours allow employees to adjust when they start and finish work within limits set by the employer. A compressed work schedule uses fixed patterns, but the work hours are distributed across fewer days. A 9/80 work schedule is a compressed work schedule, but not a flexible work schedule, because the workdays and hours are fixed.

What are the benefits of a 9/80 work schedule?

The 9/80 work schedule can benefit both employees and managers, provided the organization can commit to longer workdays and predictable coverage.

1. Extra Scheduled Day Off

Every two weeks, one additional day is designated as a scheduled day off. Employees may use this day to attend personal appointments, run errands, meet family obligations, and rest.

2. Predictable Recurring Schedule

Because the schedule repeats, employees know in advance when they have a day off. 

3. Coverage Can Be Staggered

Managers can configure individual employee or team days off on a rotating basis to ensure continuous coverage. For example, one group could be off on Monday and another on Friday. This gives the business greater flexibility for day-to-day coverage.

4. Easier Planning When Workload Is Predictable

A 9/80 schedule generally works well when workload demands, staffing requirements, and deadlines are consistent. Managers can plan around the availability of employees on regular schedules rather than adjusting coverage from week to week.

What are the challenges of a 9/80 work schedule?

A 9/80 schedule will not work for every business. 

Longer Workdays

Employees work longer days to complete their hours. This can be challenging for employees and roles that require sustained concentration or physical effort.

Overtime and Workweek Considerations

In California, there are additional rules for a 9/80 schedule. In most cases, California requires daily overtime pay for nonexempt workers who work more than eight hours in a workday. For a nine-hour workday, overtime pay is governed by an approved alternative workweek schedule. Under California Labor Code Section 511, an employer can establish an alternative workweek schedule if at least two-thirds of the affected workers approve it by secret ballot. The employer must provide a proposal upon request and send the election results to the California Division of Labor Standards Enforcement. Employers can also review overtime pay laws by state when evaluating overtime requirements. 

Because legal requirements for wage and hour laws vary by jurisdiction and employee classification, businesses are advised to consult a qualified HR or legal specialist before implementing a 9/80 work schedule.

More Complex Scheduling 

A 9/80 system adds complexity to managers’ responsibilities for scheduling workdays, start and end times, employee availability, and team coverage .It becomes even more complicated when employees have different scheduled days off. 

Potential for Less Collaboration

Employees with different scheduled days off work together less often. This affects meetings, handoffs, and projects that rely on collaboration.

Managers may need to schedule the same day off or arrange meetings with employees who have different scheduled days off.

How can managers implement a 9/80 work schedule?

A successful 9/80 schedule relies on effective organization.

1. Define the Work Pattern

A work pattern should define:

• Workdays
• Start and end times
• Regular day off (RDO)
• Pattern repetition
• Employees assigned to the pattern

A work pattern should be simple enough for employees and managers to understand and follow.  

2. Track Working Hours and Attendance

Monitor employee attendance and actual hours worked to determine whether the 9/80 work schedule has been followed. By tracking attendance, a manager can identify any issues with the schedule that may affect coverage or working hours.

3. Analyze the Results

Review attendance and hours worked after implementation. This will show how well employees are following the planned schedule and how effective the 9/80 schedule has been for the team and the organization.

How webWork supports a 9/80 work schedule

A 9/80 schedule relies on managers to track planned attendance. Scheduling and time management platforms can help managers identify patterns of recurring work and compare scheduled hours with actual work hours.

With Employee Scheduling Software, managers can create recurring shifts, set working days and times, view employee availability, and manage time off.

Using this data, managers can determine how closely employees’ attendance adheres to the planned 9/80 schedule and pinpoint areas for possible adjustment.

How 9/80 compares with other compressed schedules 

A 9/80 schedule is one of many arrangements businesses may use to organize work hours. The best option can vary based on business hours and the need for coverage, collaboration, and the nature of the work employees perform.

9/80 Work Schedule 

A 9/80 schedule gives each employee 80 hours of work over a two-week period and provides an additional day off. If that day off falls on a Friday, the employee gets a three-day weekend.

4/10 Work Schedule

A 4/10 schedule consists of four 10-hour workdays, followed by three rest days each week. This differs from a 9/80 schedule, in which 80 work hours  are spread across nine workdays over two weeks. In a 4/10 schedule, a 40-hour workweek is compressed into four workdays.

2-2-3 Schedule

A 2-2-3 schedule generally consists of two days of work, two days off, and three days of work, with this pattern reversing for the remainder of the cycle. A 2-2-3 schedule can be useful for teams that require extended or uninterrupted coverage.

DuPont Schedule

The DuPont schedule’s longer cycles are based on 12-hour work and rest periods that alternate between day and night shifts. This schedule can be useful for businesses that require 24/7 coverage.

The decision must consider operational hours, minimum staffing requirements, employee interdependence, unequal workloads, and collaboration among staff members.

For teams that operate around the clock, see our guide to 24/7 shift schedules.

Questions to Ask Before Implementing a 9/80 Schedule

Before implementation, assess workload, coverage, and collaboration requirements. The following questions can help assess whether the schedule is a good fit: 

• Will longer working days help employees complete their tasks?
• Which jobs require continuous coverage?
• Should employees have the same day off, or should days off be staggered?
• What effects will the schedule have on meetings and collaboration?
• What will happen to holidays and PTO?
• What will happen with overtime and the 40-hour workweek?
• What will happen to scheduled and actual work hours?

Final Thoughts

The 9/80 work schedule provides employees with one extra day off every two weeks. During each two‑week period, employees are expected to work 80 hours over 9 days. The schedule can benefit both the employee and the employer when the tasks to be completed, staff coverage, overtime, and collaboration requirements all remain within reasonable limits. Employees gain a predictable additional day off, while employers can structure coverage around the work schedule. However, factors such as workload, staffing coverage, overtime,and collaboration determine whether a schedule like 9/80 is appropriate. The 9/80 work schedule is not flexible, and the schedule must support business coverage. If the schedule creates overtime problems or collaboration issues, it is not the best option. Before adopting a 9/80 work schedule, employers need to define the workweek, establish the work pattern, determine scheduled hours and days, and monitor how employees spend their time.

Who uses 9/80 schedules?

Aerospace and defense companies, engineering firms, government contractors, and municipalities often use a 9/80 work schedule. These organizations generally have predictable workloads and planned staffing needs. This type of schedule can work well when staffing needs and workloads are predictable. 

Frequently Asked Questions 

Does a 9/80 schedule cause overtime?

Not directly. Overtime depends on the hours worked during the defined workweek and applicable wage and hour laws. 

Does the extra day off have to be a Friday?
Friday as a day off is fairly common. That said, the employer may choose a different day that better suits the needs of its operations.
