Annualising Working Hours in France: How It Works and How to Manage It Well

In some businesses, activity doesn't follow a steady rhythm throughout the year. Busy periods alternate with quieter ones, and organising work on a week-by-week basis quickly becomes restrictive. It's precisely to address this reality that French labour law introduced the annualisation of working hours.

But what does this mean in practice for employers? What rules need to be followed? And how do you manage hour tracking without drowning in paperwork? This guide gives you the essential answers.

What is the annualisation of working hours?

The annualisation of working hours is an organisational model that allows working hours to be spread across the full year, rather than fixed week by week. Instead of requiring 35 hours every single week, employers can schedule busier weeks during peak periods and lighter weeks during quieter ones, as long as the annual total is respected.

This arrangement is governed by the French Labour Code, notably since the Aubry laws on the reduction of working time (1998 and 2000), and must be established through a company or sector-level collective agreement.

Calculating annualised working hours: the basics

The reference number of annual working hours in France

In France, the reference number of annual working hours for a full-time employee is set at 1,607 hours. This figure is calculated as follows:

• 365 days in the year

• Minus 104 days of weekly rest (52 weeks x 2 days)

• Minus 25 days of statutory paid leave

• Minus an average of 8 public holidays

• Giving approximately 228 working days x 7 hours = 1,596 hours, rounded up to 1,607 hours to include the solidarity day

This threshold of 1,607 hours is the reference point for all annualised working hour calculations in France. Any hours worked beyond this total at the end of the reference period count as overtime.

Variable schedules, fixed total

Under the annualisation model, an employee might work 45 hours one week and 25 hours the next. What matters is that the cumulative total over the year stays within the agreed limits. Employers must inform employees of their schedules with sufficient advance notice, as defined by the collective agreement.

Which businesses can use it?

Annualising working hours is particularly well suited to sectors where activity varies significantly with the seasons or economic cycles:

• Retail and distribution: end-of-year customer peaks, sales periods

• Hospitality and catering: tourist seasons, events

• Construction and civil engineering: weather constraints and project cycles

• Agriculture: harvests and periods of intensive activity

• Health and personal services: fluctuating workloads throughout the year

For growing SMEs, this model also offers real flexibility to absorb activity variations without systematically resorting to costly overtime or temporary hires.

Legal obligations to be aware of

Annualising working hours is not something you can introduce informally. Here are the key points to know.

A collective agreement is mandatory Annualisation must be established through a company or sector-level agreement. Without this agreement, employers cannot apply the model unilaterally.

Individual hour tracking is required Each employee covered by the arrangement must have their hours tracked precisely, week by week. This tracking must be accessible and auditable, in line with the requirements set out by the Court of Justice of the EU in 2019.

Overtime is calculated at the end of the reference period Hours exceeding 1,607 over the year count as overtime. They give entitlement to a salary supplement or compensatory rest, depending on what the collective agreement provides.

Advance notice for schedule changes Employees must be informed of their schedules in advance. The notice period varies by agreement, but is generally a minimum of 7 days.

The practical challenges of annualisation

On paper, annualisation is a balanced model. In practice, managing it can quickly become complex.

Tracking individual hour balances Each employee has a running hour balance that changes throughout the year. Knowing in real time where each team member stands relative to their annual ceiling requires rigorous, continuous tracking.

Planning busy and quiet periods Anticipating staffing needs across the full year, adjusting schedules as things change and respecting advance notice requirements: it's a balancing act that few managers can handle effectively with a simple spreadsheet.

Managing absences Annual leave, sick leave and unplanned absences all affect the running hour balance. Knowing how to factor these in without creating errors at year-end is essential.

Communicating with employees An employee who doesn't understand their hour balance or doesn't know how many hours they still need to work will be less engaged and more likely to raise disputes. Transparency is key.

How to manage annualisation effectively day to day

To make annualisation an asset rather than a source of complications, here are the best practices to adopt.

1. Put a digital hour tracking system in place A digital time tracking tool automatically records each employee's hours and updates balances in real time. No more spreadsheets patched together at the end of the month.

2. Plan busy and quiet periods in advance Use a scheduling tool to visualise the workload across the year and distribute hours coherently from the start of the reference period.

3. Monitor individual balances continuously Don't wait until the end of the year to discover an overshoot. Regular monitoring allows you to adjust schedules before the situation becomes a problem.

4. Inform and involve your employees Give each employee access to their own hour balance. An informed employee is a reassured employee, and it reduces the risk of disputes at the end of the period.

5. Document and archive Keep all hour records and schedules for the legally required period. In the event of an inspection or dispute, traceability is your best protection.

In summary

Annualising working hours is a useful model for businesses whose activity fluctuates with the seasons. It offers real flexibility, provided it is implemented within the correct legal framework and managed rigorously day to day. The annual working hours reference of 1,607 hours is the central benchmark around which the entire model is organised in France.

The key to successful annualisation is tracking. The more precise and accessible it is, the fewer errors, disputes and administrative burdens it generates.
