Your French customer has reserved a Sunday shutdown and expects your technicians on site. The plant will be closed to the public, access has been arranged and the production manager has approved the timetable. None of those facts, by itself, authorises your employees to work on Sunday.
For a foreign contractor, the useful question is not simply whether the site may operate. It is whether the contractor’s own activity, the precise work performed and the place of work fall within a French route that permits weekly rest to be organised away from Sunday. That assessment should happen before travel, accommodation and production dependencies are locked in. A late error can force a crew change, a revised shutdown plan or an application that the authority has insufficient time to examine.
This guide concerns adult employees in the private sector, including employees posted temporarily to France. Transport, agriculture, young workers and profession-specific regimes require separate analysis. French rules on working time and rest form part of the protections applicable to posted employees under Article L.1262-4 of the Labour Code.
Start with three facts: activity, location and employer
A sound analysis follows three branches. First, identify the contractor’s actual business and the exact Sunday tasks. Second, locate the worksite by department, because Moselle, Bas-Rhin and Haut-Rhin have a distinct local regime. Third, identify which legal employer will assign each employee. The answer cannot be copied from the customer’s opening hours or from another contractor working beside you.
1. Does the exact activity benefit from a permanent exemption?
French law permits certain establishments whose operation or opening is required by production constraints, the nature of the activity or public needs to give weekly rest by rotation. The categories and, in some cases, the qualifying tasks are defined in Article R.3132-5, applying Article L.3132-12.
One entry is particularly relevant to industrial interventions: maintenance companies and services. It covers revision, upkeep, repair, assembly and dismantling work, including IT work, where the installations must be taken out of operation for technical reasons or where the work must be performed urgently. The wording is useful, but it is not a blanket “industrial shutdown” exemption. The contractor must be able to connect both its establishment category and the work actually assigned to the listed entry.
A new construction package, ordinary fit-out, commissioning task or convenient Sunday delivery should therefore not be relabelled as maintenance merely because it takes place while the customer’s plant is stopped. Check the applicable collective agreement as well: it may govern scheduling or compensation even where the Labour Code supplies a route for Sunday work.
There are also distinct routes for continuous work in industrial businesses and for relief shifts. Article L.3132-14 and Article L.3132-16 rely primarily on qualifying collective agreements; where the required agreement is absent, a separate application to the labour inspector may be available with supporting reasons and consultation material under Article R.3132-13. These arrangements concern a defined form of industrial organisation, not a one-off label for any Sunday project, and they are separate from the prefectural test below.
2. If there is no exemption of right, can the prefectural test be met?
Outside a usable permanent or other specific regime, Article L.3132-20 allows the prefect to authorise an alternative arrangement where simultaneous Sunday rest for all employees of an establishment would be detrimental to the public or would compromise the establishment’s normal operation. The evidence must address one of those statutory tests. A customer’s preference, a contractual milestone or the lower cost of a Sunday intervention may explain the commercial context, but does not automatically prove the legal test.
The authorisation can cover all or only certain periods of the year and may organise rest on another day for all staff, from Sunday noon to Monday noon, on Sunday afternoon with a full compensatory day by rotation every two weeks, or by rotation for all or part of the workforce. Under Article L.3132-21, its duration cannot exceed three years. That maximum is not an entitlement, an expected processing time or a guarantee that all dates requested will be accepted.
3. Is the worksite in Alsace-Moselle?
For work in Moselle, Bas-Rhin or Haut-Rhin, check the local regime before applying the ordinary national decision tree. Articles L.3134-1 to L.3134-16 establish a separate Sunday and public-holiday regime. It expressly addresses industrial establishments and building and civil-engineering worksites, and it includes its own exceptions for qualifying urgent, surveillance, cleaning and maintenance work.
The local maintenance wording and rest conditions must be tested against the actual intervention. Where an unforeseen need could otherwise cause disproportionate damage, a temporary local derogation may also be relevant. The correct local authority and procedure should be confirmed for the worksite; the ordinary Article L.3132-20 route and the rules used elsewhere in France should not be reused without that check.
The customer’s permission does not transfer to the contractor
A site owner may operate continuously, hold its own prefectural authorisation or employ staff under a permanent exemption. That position does not automatically cover an independent contractor’s employees. The French Labour Ministry’s instruction on international posting states that Sunday-work derogations are granted to foreign service providers in the same way as to employers established in France. The practical implication is that each service provider must identify and document its own legal basis.
The same caution applies to “mayor’s Sundays”. Article L.3132-26 concerns designated Sunday openings for retail establishments. It is not a general permission for construction or maintenance crews working on a closed industrial site. Geographic retail exemptions likewise should not be imported into an unrelated contractor analysis merely because the worksite is in a shopping or tourist area.
For multi-contractor shutdowns, the customer can still provide valuable evidence: why the installation must be unavailable, why the task cannot be performed during production, which operations depend on completion, and what alternatives were examined. This supports the contractor’s analysis; it does not replace the contractor’s employer decisions, employee arrangements or application where one is required.
Plan weekly rest around the Sunday intervention
Even where Sunday work has a valid basis, the rest schedule must remain lawful. Articles L.3132-1 to L.3132-3 prohibit employing the same person for more than six days in a week and require at least 24 consecutive hours of weekly rest, normally on Sunday. Those 24 hours are added to the minimum daily rest, which is normally 11 consecutive hours under Article L.3131-1.
In operational terms, a Sunday crew needs a traceable replacement-rest plan, not merely an authorisation label. Review each employee’s work before and after the intervention, travel that qualifies as working time, breaks, daily limits, weekly limits and any night-work rules triggered by the hours. A Sunday derogation does not also authorise excessive daily or weekly hours, reduce daily rest or establish night work.
Employee consent and compensation under Article L.3132-20
The prefectural route carries specific collective and individual safeguards. Under Article L.3132-25-3 I, the application must be supported by a collective agreement or, if no applicable collective agreement exists, by a unilateral employer decision adopted after consulting the Social and Economic Committee (CSE), where one exists, and approved by referendum among the employees concerned.
The collective agreement sets the compensation for employees deprived of Sunday rest and commitments concerning employment or certain disadvantaged groups or people with disabilities. The unilateral decision must also set compensation and those employment-related commitments. In that unilateral-decision route, each employee working on Sunday receives compensatory rest and pay at least equal to twice the remuneration normally due for equivalent working time.
This double-pay rule is specific to the no-agreement branch of the Article L.3132-20 route described above. French law does not impose one universal Sunday premium for every sector and every exemption. The applicable legal route, collective agreement, company agreement and employment contract must be checked before payroll instructions are issued.
For Article L.3132-20, Article L.3132-25-4 also limits Sunday work to volunteers who have given written agreement to their employer. Refusal cannot justify discrimination, misconduct or dismissal. Other Sunday-work regimes may have different employee-consent rules.
Prepare the grounds and supporting documents for the application
There is no single national checklist suitable for every department, activity and employer. Local filing channels and instructions can differ, as the procedural material published by DREETS Normandie illustrates. The statutory consultation process also makes last-minute requests risky, so obtain the current instructions from the competent authority for the place where the employees will work. Do not build the commercial schedule around a presumed filing lead time, silence rule or favourable decision.
A practical preparation file will usually address:
- the legal employer, signatory authority, business activity and applicable collective agreements;
- the exact French worksite, requested Sundays, crew size, working hours, breaks and replacement rest;
- a technical description of each Sunday task and the evidence supporting the proposed legal route;
- why simultaneous Sunday rest would harm the public or normal operation, if Article L.3132-20 is used, including alternatives considered;
- the applicable collective agreement or the employer decision, CSE material and referendum evidence required for the no-agreement route;
- written employee agreement where the chosen route requires it, plus the compensation and payroll treatment;
- a working-time schedule showing compliance before, during and after the intervention.
This is a preparation framework, not a universal statutory list. A request covering several employers, worksites or departments may require separate analyses and filings. Existing decisions should be read for their employer, establishment, activity, workforce, dates and conditions before anyone assumes that they cover a new intervention.
An illustrative shutdown: the same Sunday can produce two different answers
Assume a foreign machinery company plans to send eight adult technicians to a French factory on Sunday from 06:00 to 16:00. The customer will stop the line because the work cannot be performed while it is live. This is an illustration, not a precedent or a conclusion for a real client file.
If the contractor is a maintenance company and the documented tasks are revision, repair, assembly or dismantling that technically require the line to be out of operation, the R.3132-5 entry may provide the relevant basis for weekly rest by rotation. The employer would still verify its collective rules, employee schedules and all rest and working-time limits.
If the assignment is instead an expansion project that could be scheduled on a weekday, the same customer shutdown does not make it qualifying maintenance. The employer may need to test Article L.3132-20, assemble evidence on normal operation, put the required collective or unilateral arrangement in place, obtain written volunteers and await the decision before committing the Sunday crew. If the factory is in Moselle, Bas-Rhin or Haut-Rhin, the local regime changes the legal analysis again.
