For employers, site managers and HR teams, this framework sets demanding rules: working time on construction sites, overtime with a reduced contingent, bad weather stoppages, travel allowances and annual modulation. Understanding these mechanisms is essential for building compliant schedules and anticipating labour costs.
The French construction agreements: a multi-text architecture
The first distinctive feature of the French construction sector is its conventional fragmentation. There is no single construction collective agreement covering all employees, but several separate texts depending on the professional category and the company’s headcount.
For workers, the fundamental distinction rests on the threshold of 10 employees: companies below this threshold apply IDCC 1596, while those exceeding it apply IDCC 1597. These two texts differ on pay classifications, short-distance travel allowances and certain working time arrangements. Supervisory and technical staff (ETAM) fall under IDCC 2609, which sets rules specific to their status. Managers are covered by IDCC 2420. Public works companies follow a separate industry branch with its own agreements.
| Category | Agreement | Key feature |
|---|---|---|
| Workers (up to 10 employees) | IDCC 1596 | Headcount threshold is decisive |
| Workers (more than 10 employees) | IDCC 1597 | Enhanced travel allowances |
| ETAM (supervisory and technical staff) | IDCC 2609 | Rules specific to this category |
| Managers | IDCC 2420 | Possibility of annual day-based arrangements |
Identifying the applicable text or texts is the first prerequisite for any compliant scheduling in the construction sector. A misidentification can lead to applying the wrong overtime rules or incorrect allowances.
Organising working time on construction sites
The statutory 35-hour working week applies in construction as in any other sector. In practice, organising working time on construction sites presents specific challenges linked to the inherent uncertainties of the sector: seasonal variations, weather conditions, contractual deadlines.
Working time modulation is widely used to absorb these activity fluctuations. This arrangement allows weekly hours to vary over a reference period of up to one year without triggering overtime at every weekly excess, provided the average duration stays within legal limits. Implementation requires a collective agreement at company or establishment level defining the reference period and the maximum permitted amplitudes.
Annualisation goes further, distributing the total working hours over the full year. High-activity weeks (end of project, urgent contractual deadlines) offset lighter weeks (winter, bad weather stoppages, lower-activity periods) without each weekly excess automatically generating overtime.
For site managers overseeing multiple teams or projects simultaneously, manual management of modulated schedules quickly becomes a source of errors. Skello, designed for field-based teams, makes it possible to build and monitor multi-team schedules while tracking individual time counters in real time, with configurable alerts before critical thresholds are reached.
Overtime: reduced contingent and premium rates
One of the major specificities of the French construction collective agreement for employers is the annual overtime contingent, set at 145 hours per employee. This threshold is significantly lower than the standard legal contingent of 220 hours that applies in most other sectors.
Beyond the contingent, each additional hour of overtime entitles the employee to mandatory compensatory rest, on top of the usual premium rates. Staff representative consultation is required where applicable.
The premium rates follow the standard legal framework:
- Hours between 36 and 43 per week: 25% premium
- Hours from the 44th hour onwards: 50% premium
Under modulated or annualised schemes, overtime is triggered beyond the reference period ceiling defined by agreement, not on a weekly basis. This configuration requires rigorous tracking of individual counters throughout the year to anticipate threshold breaches.
The reduced contingent specific to construction imposes particular vigilance during activity peaks. Scheduling software that displays each employee’s remaining contingent in real time helps avoid situations where the employer discovers too late that the contingent is exhausted, with all resulting obligations.
Bad weather stoppages: employer obligations
Bad weather stoppages are a defining feature of the construction sector. When weather conditions make work on site technically impossible or dangerous, the employer can decide to suspend activity while maintaining partial compensation for employees.
The scheme is funded through the CIBTP construction leave fund. To qualify for compensation, the employee must have worked at least 200 hours during the two months preceding the stoppage and be present at the time of the suspension decision. Compensation is set at 75% of the hourly wage, capped at 55 days per year (i.e. 495 hours), with a weekly allowance of 9 hours remaining at the employer’s direct expense.
From the employer’s perspective, the procedure requires a formal decision and prompt notification of the relevant bodies. The site must resume as soon as conditions allow. Team organisation for the restart must be planned in advance to avoid disruptions.
The impact of bad weather on schedules is difficult to anticipate, but precise tracking of hours lost is essential: during the recovery phase, catch-up activity often generates heavy weeks that can quickly exhaust the overtime contingent. Documenting each stoppage as it occurs also simplifies reimbursement requests with the CIBTP.
Travel and displacement: what counts as working time
The issue of travel time recurs constantly in construction, where employees work on geographically dispersed sites, sometimes far from their home or regular depot. The regulatory framework distinguishes several situations with very different consequences.
Home-to-site travel does not constitute effective working time. Instead, employees receive displacement allowances (short-distance or long-distance allowances depending on distance and duration), calculated on scales defined by geographic zones and regularly updated. These hours are not counted as working time.
Travel between two sites during the same working day is treated as effective working time. If this travel causes the employee to exceed weekly thresholds, overtime is generated. The same applies to mandatory stops at the depot before reaching the site: the time spent travelling from the depot to the site is generally classified as effective working time depending on how the work is organised.
Misclassification of travel times can lead to significant back-pay claims during a labour inspectorate audit. The risk is particularly significant for teams that move between several sites in a single day or routinely pass through a central depot.
Mandatory rest periods and maximum working hours
Statutory maximum working hour limits apply to construction employees without any sector-specific derogation:
- Daily rest: minimum 11 consecutive hours between two working days
- Weekly rest: minimum 35 consecutive hours
- Maximum daily duration: 10 hours, unless a derogation is granted by collective agreement or the labour inspectorate
- Maximum weekly hours: 48 hours in any single week, 44 hours on average over 12 consecutive weeks
On sites under pressure (imminent handover, tight contractual deadlines), these limits are often close to being reached. Schedules must incorporate these constraints from the planning phase to avoid violations. Building weeks that respect maximum limits upfront prevents emergency situations and reduces the risk of labour disputes.
Digital tools for compliant construction scheduling
Managing working time in construction involves multiple simultaneous constraints: multiple agreements depending on employee status, an overtime contingent reduced to 145 hours, unforeseeable bad weather stoppages, travel time to classify, and modulation to track across the whole year. Building schedules manually in this context exposes companies to costly errors during inspections.
Skello, designed for field-based teams, addresses these constraints directly: multi-team schedule building and distribution, individual overtime counter tracking, alerts before contingent thresholds are reached, and automated payroll export. These features are especially useful for site managers overseeing teams across multiple sites with different employment statuses.
For construction companies recruiting and training their workers and site supervisors, Empowill offers talent management and training tracking modules, particularly useful for managing mandatory certifications (working at height, CACES, electrical qualifications).
Other sectors subject to demanding collective agreements face comparable challenges. The restaurant collective agreement requires precise management of atypical hours and night work. The fast-food collective agreement presents similar scheduling constraints for rotating teams. The metallurgy collective agreement shares the challenges of modulation and multi-site teams. The time tracking software guide 2026 provides an overview of tools available to automate this monitoring and reduce non-compliance risk.
Frequently asked questions
Does the French construction collective agreement apply to all construction companies?
No. The French construction sector is covered by several separate agreements depending on employee category and company size. Workers in companies with more than 10 employees fall under IDCC 1597, while those in companies with up to 10 employees fall under IDCC 1596. Supervisory and technical staff (ETAM) are covered by IDCC 2609, and managers by IDCC 2420. Public works companies follow their own separate agreements. Identifying the correct text is a prerequisite for any compliant schedule management.
What is the annual overtime contingent in the French construction sector?
The annual overtime contingent in the French construction sector is set at 145 hours per employee, compared to 220 hours in most other sectors. This lower threshold requires careful monitoring of individual time counters, especially during peak activity periods or when multiple projects overlap.
What happens to employees during a bad weather stoppage on a French construction site?
During a bad weather stoppage, eligible employees receive compensation equal to 75% of their hourly wage, partly funded through the CIBTP construction leave fund. To qualify, the employee must have worked at least 200 hours over the two preceding months and be present at the time of the stoppage. Compensable stoppages are capped at 55 days per year, with a weekly allowance remaining at the employer's expense.
Is commuting time from home to the construction site considered working time?
No. In the French construction sector, home-to-site travel is not considered effective working time. Instead, employees receive travel allowances (short or long-distance displacement allowances depending on the distance). However, travel between two sites during the same working day, or mandatory stops at the depot before reaching the site, are generally considered effective working time and must be recorded as such.
How can a construction company implement flexible working time arrangements in France?
Implementing modulated working time in France requires a collective agreement at company or establishment level. This agreement must specify the reference period, minimum and maximum weekly hours, counting methods and the conditions under which overtime is triggered at the end of the reference period. Without such an agreement, only the standard weekly regime applies, with overtime triggered from the 36th hour.
