Compliance with Labour Legislation: Employer's Obligations

Introduction: why social compliance is a strategic issue

Compliance with labour legislation is one of the absolute priorities for any business leader in France. Whether it is a small business with five employees or a group with several hundred collaborators, the employer's obligations cover a very wide spectrum: formalisation of contracts, mandatory notices, working hours, health protection, legal registers or even declarative obligations. Non-compliance with these rules exposes the company to criminal sanctions, labour court convictions and reputational damage. This article provides an exhaustive overview of employer obligations in force in 2026, incorporating recent developments from the Labour Ordinances, the Professional Future Act and European directives transposed into French law.

Obligations at recruitment: establishing the employment relationship on solid foundations

From the moment the first employee is hired, the employer must complete a precise set of formalities under penalty of contract nullity or recharacterisation of the employment relationship.

Prior Declaration to Employment (DPAE)

The DPAE must be transmitted to the URSSAF no later than 8 days before the employee's start date (article L. 1221-10 of the Labour Code). It triggers the employee's registration with Social Security, affiliation to occupational medicine and the opening of unemployment insurance rights. The absence of DPAE constitutes the offence of undeclared work (article L. 8221-5 of the Labour Code), punishable by 3 years' imprisonment and €45,000 fine for an individual.

Drafting and delivery of the employment contract

For any fixed-term contract (CDD), the contract must be provided to the employee within 2 working days following recruitment (article L. 1242-12). For permanent contracts (CDI), although the Labour Code does not impose written form for full-time jobs, European Directive 2019/1152 on transparent and predictable working conditions now requires the employer to provide a written document containing essential information (notice period, salary, applicable collective agreement, etc.) within 7 calendar days following the employee's start date.

Electronic signature for HR considerably simplifies this step: contracts can be generated, signed and archived in minutes, guaranteeing traceability and probative value compliant with the eIDAS regulation.

Pre-employment medical examination

Since the 2016 Labour Act (article L. 4624-1), the pre-employment medical examination was replaced by an information and prevention visit (VIP), to be carried out within 3 months of the start date (or before for high-risk positions). The employer must ensure affiliation to an inter-company or autonomous Occupational Health and Safety Service (SPST).

Obligations during execution of the employment contract

The employment relationship requires the employer to exercise constant vigilance on many operational and administrative fronts.

Compliance with maximum working hours and right to rest

The Labour Code sets strict limits:

• Legal duration: 35 hours per week (article L. 3121-27)

• Maximum daily duration: 10 hours (article L. 3121-18), increased to 12 hours by collective agreement

• Absolute maximum weekly duration: 48 hours in an isolated week, 44 hours on average over 12 consecutive weeks (article L. 3121-20)

• Daily rest: 11 consecutive hours (article L. 3131-1)

• Weekly rest: 35 consecutive hours (article L. 3132-2)

Since law no. 2016-1088, the right to disconnect also constitutes an obligation to negotiate in companies with 50 or more employees (article L. 2242-17).

Protection of health and safety at work

The obligation to ensure safety has evolved towards a reinforced best-efforts obligation since the Air France rulings of 2015 (Cass. soc., 25 Nov. 2015). The employer must:

• Assess occupational hazards and record them in the Single Document for Risk Assessment (DUERP), updated at least once a year (articles R. 4121-1 to R. 4121-4)

• Since the Occupational Health Act of 2 August 2021, the DUERP must be kept for 40 years and deposited on a national digital portal

• Train employees on identified hazards

• Implement the annual risk prevention programme for companies with at least 50 employees

Payroll management and social declarations

The provision of a payslip is mandatory at each salary payment (article L. 3243-2). Since 1 January 2019, the simplified payslip has been generalised. The Nominative Social Declaration (DSN) replaces almost all periodic social declarations and must be transmitted monthly on the scheduled date (generally the 5th or 15th of the following month).

For further information on the dematerialisation of HR flows, electronic signature in the enterprise provides a complete solution for secure document management.

Obligations regarding notices and mandatory registers

Mandatory notices in the workplace

Any employer must display in its premises, in a location accessible to all employees, a set of mandatory information including:

• The contact details of the competent Labour Inspectorate

• Texts relating to professional equality between women and men

• Safety and fire prevention instructions

• The internal regulations (mandatory from 50 employees, article L. 1311-2)

• Provisions relating to moral and sexual harassment, including the contact details of the Ombudsman

• The applicable collective agreement (its title is sufficient, but the text must be accessible)

The Law no. 2023-1107 of 29 November 2023 implementing the national inter-professional agreement on value-sharing added new information obligations in companies with 11 to 49 employees concerning participation schemes.

Mandatory registers

The employer must maintain several registers, including:

• Unique personnel register (article L. 1221-13): lists in chronological order all employees, trainees and temporary workers; kept for 5 years after the date of departure

• Register of minor work accidents (article R. 441-3 of the Social Security Code): for employers who have obtained authorisation from the CPAM

• Safety register for periodic equipment verifications

• Register of employee representatives and minutes of CSE meetings (from 11 employees)

The dematerialised keeping of these registers is permitted provided integrity and accessibility guarantees are provided. The complete guide to electronic signature details the technical conditions required to ensure the legal value of digital documents.

Obligations relating to representative bodies and collective bargaining

The Social and Economic Committee (CSE)

Since the Macron Ordinances of 22 September 2017, the CSE merges the former employee representatives, works council and occupational health and safety committee. Its establishment is mandatory from 11 employees for 12 consecutive months (article L. 2311-2). Elections must be held every 4 years. Failure to establish the CSE exposes the employer to obstruction charges, punishable by 1 year's imprisonment and €7,500 fine (article L. 2317-1).

Mandatory annual negotiations (NAO)

In companies with union representatives, the employer is required to open negotiations annually on:

• Remuneration, working time and value-sharing (article L. 2242-1)

• Professional equality between women and men and quality of life and working conditions (QVCT, article L. 2242-17)

The obligation concerns the opening of negotiations, not the conclusion of an agreement. However, in the absence of an agreement on professional equality, the company may be penalised when applying for public contracts.

Professional equality index

Since the Professional Future Act of 5 September 2018, companies with at least 50 employees must calculate and publish annually before 1 March their gender equality index on their website and declare it on the Labour Ministry portal. A score below 75/100 requires setting improvement targets. A score below 85/100 triggers a penalty that can reach 1% of the payroll from 1 September 2022 (decree no. 2022-243).

To facilitate the management of all these documents and accelerate the signing of amendments related to NAO or company agreements, tools such as the AI contract generator by Certyneo allow producing compliant documents that are immediately signable.

Legal framework applicable to employer obligations

Employer obligations in labour law are based on a dense corpus of legislative and regulatory provisions, structured around several levels of standards.

Labour Code: primary source, it is structured into legislative (L.) and regulatory (R./D.) parts. Fundamental articles include:

• Art. L. 1221-10 (DPAE), L. 1242-12 (CDD delivery)

• Art. L. 3121-18 to L. 3121-27 (maximum working hours)

• Art. L. 3131-1, L. 3132-2 (daily and weekly rest)

• Art. R. 4121-1 to R. 4121-4 (DUERP)

• Art. L. 1311-2 (internal regulations), L. 1221-13 (personnel register)

• Art. L. 2311-2, L. 2317-1 (CSE and obstruction charges)

• Art. L. 2242-1, L. 2242-17 (NAO)

• Art. L. 8221-5 (undeclared work)

Law no. 2018-771 of 5 September 2018 called "Professional Future": establishes the professional equality index, reforms vocational training and apprenticeship.

Law no. 2021-1018 of 2 August 2021 to strengthen occupational health prevention: reforms SPST, extends DUERP retention period to 40 years, introduces prevention passport.

Law no. 2023-1107 of 29 November 2023 implementing the national inter-professional agreement on value-sharing: extends information obligations to companies with 11 to 49 employees.

European Directive 2019/1152 on transparent and predictable working conditions: transposed into French law by decree no. 2022-1173 of 24 August 2022, it requires the provision of written information within 7 days following recruitment.

GDPR Regulation no. 2016/679: the processing of employees' personal data (payroll data, time tracking, monitoring) requires a legal basis (contract execution, legal obligation), employee information (articles 13-14 GDPR) and retention period proportionate to the purpose. The processing register is mandatory. CNIL published specific recommendations on cybersurveillance of employees (deliberation no. 2023-010).

Dematerialisation and electronic signature: the dematerialised provision of payslips (article L. 3243-2) and electronic signature of contracts are governed by eIDAS Regulation no. 910/2014 and the Civil Code articles 1366 (electronic writing has the same probative force as paper writing) and 1367 (electronic signature consists of using a reliable identification process). For employment contracts, an advanced or qualified electronic signature (ETSI EN 319 132 and EN 319 411 standards) is recommended to guarantee maximum probative value in case of employment tribunal proceedings.

Risk of sanctions: apart from the fines and imprisonment mentioned above, the employer faces URSSAF adjustment, condemnation to employment tribunal damages, contract termination nullity, and in serious cases, administrative closure of the establishment.

Usage scenarios: social compliance in practice

Scenario 1 — An 80-employee industrial SME facing URSSAF inspection

An SME in the metalworking sector employing 80 employees is subject to URSSAF inspection covering 3 fiscal years. The inspector finds that 12 fixed-term contracts were provided to employees with an average delay of 6 working days after the start date, exceeding the legal 2-day deadline. In the absence of delivery proof (no receipt signature, no timestamp), the contracts are recharacterised as permanent, generating a social contribution adjustment of €35,000, plus late payment penalties. After this audit, the SME deploys an electronic signature solution allowing contracts to be generated, sent and archived with time-stamped proof of delivery. In the following fiscal year, 100% of fixed-term contracts are provided within legal deadlines, with the company having proof that can be produced in case of future inspection. The administrative gain is estimated at approximately 3 hours per recruitment.

Scenario 2 — An ETI professional services company needing to publish its equality index

A consulting company with 220 employees, 55% of whom are women, must publish its equality index before 1 March each year. For the previous fiscal year, its score reached 72/100, below the 75/100 threshold. The company has 3 years to reach this threshold or face a penalty of up to 1% of the annual payroll (approximately €180,000 for a payroll of €18M). In response, it negotiates with its union representatives a professional equality agreement, formalised and signed electronically. The agreement is deposited on the TéléAccords platform of the Labour Ministry. Dematerialised signature reduces the time to finalise the agreement from 3 weeks to 4 days, while guaranteeing traceability of each union representative's signature.

Scenario 3 — A franchise network managing several dozen establishments

A quick-service restaurant network comprising around thirty establishments employs an average of 15 employees per site, with high seasonal turnover. Each seasonal opening generates several dozen contracts to sign within days. Paper management mobilised two full-time administrative staff solely for collection, printing and archiving of contracts. By adopting a electronic signature platform for HR integrated with the existing HRIS, the network reduces the average contract signing time from 4.5 days to less than 6 hours. The rate of contracts provided outside legal deadlines drops from 22% to less than 1%. Automatic archiving guarantees immediate document availability in case of Labour Inspectorate inspection, reducing the time needed to prepare for an inspection by approximately 70%.

Conclusion

Compliance with labour legislation is a complex, multidimensional discipline in constant evolution. From recruitment obligations to management of representative bodies, through occupational health and payroll compliance, each breach exposes the employer to significant financial, criminal and reputational risks. In 2026, the dematerialisation of HR processes — driven by eIDAS-compliant electronic signature — is one of the most effective levers for combining operational agility with document compliance.
