9 Day Fortnight

>> HR Glossary/  General HR Terms / 9 Day Fortnight

What is a 9 day fortnight?

A 9 day fortnight is a flexible work arrangement where employees work a full-time schedule over nine days within a two-week period instead of the traditional ten days. 

This model allows for an extra day off every fortnight (two weeks), giving employees an extra day off without cutting down on productivity or pay.

How a 9 day fortnight works

In a 9 day fortnight, the total number of work hours remains consistent with a standard full-time schedule, but these hours are distributed over nine days instead of ten. Typically, this involves extending the workday slightly so employees can accumulate enough hours to take an additional day off every two weeks.

However, the 9-day fortnight can also be set up by simply reducing work hours without any drop in salary. Employees will keep their regular hours and get every other Friday (or another day of the week) off. This approach is less common but still boosts productivity in the same ways.

9 day fortnight vs. 4 day work week: The differences

9 day fortnight
4 day work week

Work schedule

Employees work for 9 days over a two-week period, usually taking every second Friday off.

Employees work for 4 days each week, typically having Fridays or Mondays off to get a long weekend.

Daily hours

Daily working hours are often extended to maintain full-time hours over 9 days. For example, an 8-hour day might become a 9-hour day.

Daily hours remain the same, with the total weekly work hours reduced to fit into 4 days.

Impact on pay

Typically does not affect pay as total hours worked remain the same.

May result in reduced pay unless the employer decides to maintain full-time pay for fewer working hours.

Cultural shift required

Necessitates minor adjustments as teams need to adapt to varying schedules bi-weekly.

Demanding shift since the entire organizational schedule compresses into fewer days.

The key differences between a 9 day fortnight and a 4 day work week.

Benefits of implementing a 9 day fortnight

  • Better work-life balance: By providing an extra day off every fortnight, employees can enjoy more personal time for family, hobbies, or rest, leading to better mental and physical health.
  • Increase in productivity: Some studies suggest that compressed work schedules can lead to increased productivity. Employees might work more efficiently to complete their tasks within the shortened work period, knowing they have an extended break coming up.
  • Talent attraction & retention: Offering a 9-day fortnight can make an organization more attractive to potential employees who value flexibility and work-life balance. 
  • Environmental benefits: With one less day of commuting every two weeks, there’s a reduction in carbon emissions and traffic congestion. This not only benefits the environment but can also reduce transportation costs and stress for employees.

HR tip

Switching to a 9 day fortnight can boost employee wellbeing, spike productivity, and improve work-life balance. It also makes your company more attractive to top talent by showing you value their time and life outside of work.

How do you calculate a 9 day fortnight?

Here’s how to calculate a 9 day fortnight, assuming a standard workweek of 40 hours.

  1. Total hours: First, determine the total number of hours an employee is supposed to work over the two-week period. For a standard 40-hour workweek, this would be 80 hours in two weeks.
  2. Daily hours: Then, divide the total hours by 9 days to find out how many hours the employee needs to work each day during the 9 day fortnight.
  3. Adjust schedule: The result will give you the number of hours the employee needs to work each day over the 9 days to maintain their full-time status and ensure all work hours are covered.

The formula

Daily hours =Total hours
9

For a standard 40-hour workweek, an employee would need to work approximately 8.89 hours, or 8 hours and 54 minutes each day over the 9 days of the fortnight, to meet their total required hours.

9 day fortnight example

Here’s an example of how a 9 day fortnight work schedule could be implemented, assuming an employee typically works from Monday to Friday, with weekends off, and aims to work a total of 80 hours over a two-week period:

Week 1Week 2
Monday: Work 8 hours 54 minutesMonday: Work 8 hours 54 minutes
Tuesday: Work 8 hours 54 minutesTuesday: Work 8 hours 54 minutes
Wednesday: Work 8 hours 54 minutesWednesday: Work 8 hours 54 minutes
Thursday: Work 8 hours 54 minutesThursday: Work 8 hours 54 minutes
Friday: Work 8 hours 54 minutesFriday: Off (This is the extra day off in the fortnight)
Case study: CharlieHR

CharlieHR, a company offering HR advice and software, trialled a 9-day fortnight for nine months. The results included:

  • a 24% decrease in work-related stress
  • a 14% increase in the team’s ability to disengage from work
  • an 11% increase in productivity
  • and 40% of hiring candidates cited the 9-day fortnight as a top reason for wanting to join the company.

The policy has now been rolled out as a permanent adjusted work week policy across the business.

How to implement a 9 day fortnight: Tips for HR

  1. Assess the suitability for your organization: Determine whether your business operations and employee roles are compatible with a compressed work schedule. Consider the potential impact on workload, client service, and whether tasks can be reorganized to fit the new schedule.
  2. Consult with stakeholders: Engage employees, managers, and unions in discussions to ensure the proposed schedule change is feasible and beneficial. Conducting surveys or meetings to gather input and address concerns can help gauge interest and identify potential challenges.
  3. Implement a trial period: Implement a pilot phase in select departments to help you identify potential hurdles and allow for adjustments before a full rollout. Collecting feedback to understand employee satisfaction and any impact on productivity.
  4. Develop a clear policy: Develop a comprehensive policy that details the implementation of the 9 day fortnight. This should cover working hours, handling of overtime, and scheduling days off. 
  5. Monitor and adjust: Establish performance metrics to evaluate the effect of the 9 day fortnight. This ongoing assessment will guide necessary adjustments to optimize the schedule.
