Since 1 January 2021, a British citizen who wants to take a job in France is treated as a third-country national. The Withdrawal Agreement protected Britons who were already resident and working in France before the end of the transition period, but anyone arriving afterwards starts from the same place as any other non-European applicant: no right to work arises from the passport alone, and no employment contract is valid unless the immigration paperwork supports it. In practice two locks guard the door to lawful employment. The first is the autorisation de travail, the work authorisation, which the employer must obtain before the employee starts. The second is the carte de séjour, the residence permit, which gives the worker the right to remain in France and, in most salaried cases, cannot be issued without that authorisation. This article explains both locks in order: who needs an authorisation and why, how employers apply and where applications fail, which residence card follows which contract, what happens when employment ends, and which remedies exist when the préfecture (the local arm of the State that decides on residence) says no. Readers who are still at the arrival stage should read this guide together with our arrival guide for British newcomers on French visas and residence cards, which covers the long-stay visa routes that bring most Britons to France in the first place.

I. Before the first day at work: the authorisation your employer must secure

A. Why a British citizen now needs an autorisation de travail, and what the employer risks without one

Before Brexit, a British worker moved to France under European movement rights and needed no permission to work. That regime ended with the transition period. Today the starting point is Article L5221-2 of the Labour Code, which provides: “Pour entrer en France en vue d’y exercer une profession salariée, l’étranger présente : 1° Les documents et visas exigés par les conventions internationales et les règlements en vigueur ; 2° Un contrat de travail visé par l’autorité administrative ou une autorisation de travail.” In plain terms, a foreign worker must show either an approved employment contract or a work authorisation, and a British newcomer has no shortcut around this rule. The rule bites even where the person already holds a residence document, because Article L5221-5 of the Labour Code adds: “Un étranger autorisé à séjourner en France ne peut exercer une activité professionnelle salariée en France sans avoir obtenu au préalable l’autorisation de travail mentionnée au 2° de l’ article L. 5221-2 .” Residence alone does not authorise salaried work; the prior authorisation is a separate condition, and starting work without it exposes both sides.

The duty sits squarely on the employer, not the employee. Article L5221-8 of the Labour Code states: “L’employeur s’assure auprès des administrations territorialement compétentes de l’existence du titre autorisant l’étranger à exercer une activité salariée en France, sauf si cet étranger est inscrit sur la liste des demandeurs d’emploi tenue par l’institution mentionnée à l’article L. 5312-1 .” A careful British candidate therefore helps the hiring company by arriving with a file that makes this verification easy: passport, visa, diplomas, employment contract draft and any prior residence documents, so the employer can apply on the ANEF platform (the Administration Numérique pour les Étrangers en France, the online portal for foreign-nationals procedures) without delay. Employers who skip the check face a double sanction. On the civil side, Article L8251-1 of the Labour Code lays down the blunt prohibition: “Nul ne peut, directement ou indirectement, embaucher, conserver à son service ou employer pour quelque durée que ce soit un étranger non muni du titre l’autorisant à exercer une activité salariée en France.” On the criminal side, Article L8256-2 of the Labour Code provides that “Le fait pour toute personne, directement ou par personne interposée, d’embaucher, de conserver à son service ou d’employer pour quelque durée que ce soit un étranger non muni du titre l’autorisant à exercer une activité salariée en France, en méconnaissance de l’article L. 8251-1 , est puni d’un emprisonnement de cinq ans et d’une amende de 30 000 euros.” Five years’ imprisonment and a 30,000 euro fine concentrate an employer’s mind, and they explain why French human-resources departments treat the authorisation as a condition of hiring rather than a formality.

A Paris case shows how these rules play out inside a real employment dispute. An employee working part-time was dismissed after the prefect refused a new work authorisation covering full-time work, and the employer relied on Articles L8251-1 and L8256-2 to justify an immediate dismissal. The Court of Appeal of Paris, in a judgment of 18 November 2025 (RG 22/08923, official record here), examined what the employee was still allowed to do rather than what had been refused: “En conséquence, la cour retient que M. [V] pouvait continuer à travailler à temps partiel à titre accessoire jusqu’au 10 avril 2021 et que dès lors, son licenciement est dépourvu de cause réelle et sérieuse.” The dismissal lacked real and serious cause because the employee remained authorised to work part-time on an ancillary basis until the expiry of his receipt. The court added the decisive principle for every refusal file: “de sorte que le refus d’autorisation afférente à un travail à temps complet ne remet pas en cause ce récépissé.” A refusal aimed at one specific working pattern does not cancel a valid existing permission covering another. For a British worker, the lesson is practical: keep every récépissé (the official receipt issued while a residence application is examined, which often carries its own right to work with stated dates), check exactly what it allows, and never assume that one refusal wipes out everything.

B. How the employer applies for the authorisation, and the three reasons most British files fail

Since the 2021 reform, the employer files the request online through the ANEF portal, and the Dreets (the regional directorate for employment, formerly known as the Direccte) examines it before any residence card can follow. The file must show the identity and qualifications of the future employee, the reality of the post, the draft contract with pay and working time, and, for most posts, evidence that the position could not be filled on the local labour market. That last condition, known as the opposabilité de la situation de l’emploi (the rule that the state of the employment market can be held against the application), is the first great cause of refusal: where unemployment in the occupation and region is significant, the administration can refuse simply because a candidate already available in France could take the job, unless the post appears on a shortage list or the salary and qualification level take the file outside that test. Highly paid executive posts, intra-group transfers and researcher positions follow eased tracks, but an ordinary British applicant for a standard salaried post faces the full labour-market test.

The second cause of refusal is pay and qualification mismatch. The administration compares the offered salary with the statutory minimum wage (the Smic), with the collectively agreed minimum for the sector, and with the level corresponding to the diplomas produced. A British degree must be explained: an unexplained foreign diploma, a salary at the very floor of the pay scale for a post described as skilled, or a part-time contract whose hours look designed to fit a threshold rather than a genuine need all invite refusal. Candidates should attach sworn translations of diplomas, a clear job description, and evidence of how the salary was set. The third cause is file incoherence: a contract signed before the authorisation is granted, inconsistent dates between the visa and the intended start, a company with tax or social-security arrears, or accommodation and identity documents that do not match. None of these defects is fatal if caught early, because the employer can complete or correct the file, but each one costs weeks, and weeks matter when a visa window or a tenancy is running.

Timing discipline decides many cases. The authorisation must pre-date the start of work, yet employers often want the new hire to begin on Monday. A British worker who starts early, even with the employer’s blessing, works unlawfully and hands the prefecture a ready-made reason to refuse the later residence card. The safer sequence is written into the hiring letters used by careful companies: conditional offer, authorisation request, authorisation granted, then visa or residence application, then start date. Where the worker is already in France on another status, such as a student or visitor status, the change of status (changement de statut) follows the same logic and the worker must not start the new activity before the new permission arrives. Keep copies of every upload and every acknowledgment from the portal, because a later challenge to a refusal turns on proof of what was filed and when. The service-public.fr guidance pages and the gov.uk living-in-France guides both describe this employer-led sequence, and both confirm the same point: the British employee prepares the file, but the employer files it, and work starts only after the authorisation lands.

II. After the green light: the residence card, and how to fight a refusal

A. Which salarié card follows which contract, and what losing your job really changes

Once the work authorisation is granted, the residence card follows the contract. Article L421-1 of the Ceseda (the Code on the entry and residence of foreign nationals, which gathers the immigration rules) states that a foreign worker on a permanent contract ‘se voit délivrer une carte de séjour temporaire portant la mention ” salarié ” d’une durée maximale d’un an’. The salarié temporary residence card therefore lasts up to one year and is tied to the open-ended employment relationship, while Article L421-3 of the Ceseda provides the mirror rule for fixed-term contracts and postings: the worker ‘se voit délivrer une carte de séjour temporaire portant la mention ” travailleur temporaire ” d’une durée maximale d’un an’, issued for the length of the contract or posting within the one-year ceiling and renewed for the same period. Both cards require the prior work authorisation described in Part I, so the two procedures form a chain: no authorisation, no card, and a broken link at either stage stops the whole process. British researchers, lecturers and doctoral staff use a different track, the multi-year talent-chercheur card, of which Article L421-14 of the Ceseda says: “Cette carte permet l’exercice d’une activité professionnelle salariée dans le cadre de la convention d’accueil ayant justifié la délivrance du titre de séjour.” The hosting agreement (convention d’accueil) signed with an approved research or higher-education body defines the permitted work, and salaried activity outside that agreement is not covered.

Renewal is where British workers most often stumble. A salarié card is renewed on proof of continued employment, pay slips, tax notices and, increasingly, evidence of integration and respect for republican principles. Involuntary unemployment does not automatically end residence: the Ceseda extends the card where the worker has involuntarily lost the job, and at the following renewal the prefecture decides on residence by reference to the unemployment insurance entitlements earned. Voluntary resignation without a new project, long gaps between contracts, or a move to self-employment without changing status are far more dangerous, because the card’s ground disappears and the renewal can be refused. Posted workers (salariés détachés) sent by a British employer to France face a parallel trap: their travailleur temporaire card follows the posting, and when the posting ends the card’s basis ends with it, so anyone who wants to stay must secure a new status before the expiry date rather than afterwards.

Deadlines govern everything after a dismissal or a contract’s end, and a Montpellier case is a warning worth reading twice. An employee dismissed in disputed circumstances brought his claims before the employment tribunal, saw them declared inadmissible as time-barred, appealed, obtained an appellate ruling that overturned the first judgment and declared his claims admissible, and then lost on the merits when the court ruled: “Déboute M. [V] [S] de l’intégralité de ses demandes” (Court of Appeal of Montpellier, 10 June 2026, RG 23/06374, official record here). The procedural history, which notes expressly “Vu l’arrêt avant dire droit mixte du 17 décembre 2025 ayant infirmé le jugement entrepris en toutes ses dispositions et déclaré les demandes de M. [V] [S] recevables”, shows a worker spending years fighting about whether his case could even be heard. The underlying time-bar rule is Article L1471-1 of the Labour Code: “Toute action portant sur la rupture du contrat de travail se prescrit par douze mois à compter de la notification de la rupture.” Twelve months from notification of the termination to challenge the dismissal: a British worker who waits, who hopes the prefecture will sort matters out first, or who returns to the United Kingdom to think, can come back to find the employment claim dead even where the residence fight is still alive. Run both clocks from day one, diary every expiry date, and treat the employment dispute and the immigration file as two fronts of the same case.

B. Refusal of the card, OQTF on the doormat, and the remedies that actually work

A refusal rarely arrives alone. The standard pattern is a refusal of the residence card accompanied, in the same envelope or shortly after, by an OQTF, an obligation to leave French territory, which orders departure within thirty days or, in voluntary-departure cases, sets the clock running immediately. The legal bridge between the two is Article L611-1 of the Ceseda, whose third ground covers exactly this situation: “L’étranger s’est vu refuser la délivrance d’un titre de séjour, le renouvellement du titre de séjour, du document provisoire délivré à l’occasion d’une demande de titre de séjour ou de l’autorisation provisoire de séjour qui lui avait été délivré ou s’est vu retirer un de ces documents ;” A refused British worker therefore faces removal mechanics as well as disappointed plans, and the response must address both documents together rather than appealing the refusal while ignoring the removal order, because the OQTF continues to run and can be enforced.

The first response is administrative and fast: a recours gracieux (a request asking the prefect to reconsider) or a recours hiérarchique (the same request addressed to the Minister of the Interior), filed within the short time limit printed on the decision, asking for withdrawal of the refusal on specified grounds. These remedies cost nothing, keep dialogue open, and sometimes succeed where the refusal rested on a missing document or a misunderstanding about the contract. Their weakness is that the administration is never obliged to answer, and silence maintained for two months counts as an implied rejection, so the worker must prepare the court case in parallel rather than waiting hopefully. The second response is judicial: an action for excess of power (recours pour excès de pouvoir) before the administrative court (tribunal administratif) seeking annulment of the refusal and, where one was issued, of the OQTF, combined where removal threatens with an urgent application to suspend enforcement. British applicants should know that the judge reviews the file as it stood on the day of the decision: documents produced for the first time before the court carry less weight than a complete administrative file, which is why the advice in Part I about keeping every upload and acknowledgment matters so much at this stage.

Three arguments win these cases more often than any others. The first is legal error on the applicable status: the prefecture applies the labour-market test to a post that is exempt, demands an authorisation the worker’s current receipt already supplies, or treats a student receipt authorising ancillary part-time work as if it authorised nothing, the exact mistake corrected in the Paris judgment quoted above. The second is manifest error of assessment: the file plainly shows the salary, qualifications and genuine post, and no reasonable reading supports refusal. Evidence here means payslips, the signed contract, the shortage-list extract for the occupation, the sworn translation of the British diploma with its comparability statement, and proof of the company’s compliance with tax and social-security duties. The third is disproportionate interference with private and family life: a Briton settled for years, with a partner, children in French schools, a tenancy and tax history in France, can argue that refusal destroys an established life for a correctable defect. This argument needs documents, not adjectives: school certificates, tax notices, rental receipts, and proof of the length of residence. An argument raised without its papers is a wish; the same argument with a dated bundle is a case.

Dismissal cases add an employment-law front that must be fought before the conseil de prud’hommes, the employment tribunal that hears individual disputes between employers and employees. Where the employer dismisses because the authorisation was refused, the tribunal asks whether the dismissal had real and serious cause on the evidence as it stood, including any surviving permission such as the receipt discussed in the Paris case. A dismissal without such cause opens compensation under the statutory scale: the Paris court applied Articles L1235-3 and L1235-4, awarding damages for the abusive break and ordering reimbursement of unemployment benefits, after recalling that reintegration with preserved benefits may be proposed where neither party refuses it. Where the dismissal was lawful because no permission of any kind survived, the worker’s energy belongs to the immigration challenge rather than the employment claim, and the twelve-month clock of Article L1471-1 still runs in the background. Either way, the British worker should leave France with three folders complete: the immigration file with every decision and receipt, the employment file with contract, payslips and dismissal letter, and a dated diary of every deadline. Cases are won by workers who can prove what happened and when; they are lost by workers who remember roughly.

Conclusion

Working lawfully in France after Brexit as a British citizen means satisfying two authorities in sequence: the employment administration, which grants the work authorisation on the employer’s application, and the prefecture, which issues the residence card on the strength of that authorisation. The prohibitions are severe, with imprisonment and heavy fines for employers who use unauthorised foreign labour, yet the system is navigable where the file is prepared honestly and filed in the right order. The Paris case law shows that a targeted refusal does not destroy every surviving permission, the Montpellier litigation shows that limitation periods punish delay on the employment front, and the Ceseda shows that each card follows its contract and each refusal can carry a removal order that must be challenged alongside it. A British candidate who understands the labour-market test, prices the post at a defensible salary, keeps every receipt and acknowledgment, diaries the twelve-month dismissal clock and the removal-order deadlines, and answers a refusal with administrative reconsideration and court action together gives himself or herself the strongest possible position. The door is narrower than it was before Brexit, but it opens for files that are complete, coherent and fought on time.
