Which modifications require an amendment?

Any modification of an essential element of the employment contract: salary (decrease or increase), working time (part-time ↔ full-time), role (position change with qualification impact), work location (outside the geographic area without mobility clause), classification, non-compete clause. Minor changes (schedule reorganisation without duration change) do NOT require an amendment.

Which signature level: SES, AES or QES?

Advanced signature (AES) is the recommended standard for an amendment. It provides presumption of reliability (art. 1367 CCiv), identity verification by SMS OTP and qualified timestamp — elements required for labour-court contestation. SES is undersized. QES is reserved for very high-stakes changes (business transfer, art. L1224-1 transfer).

Can the employee refuse to sign the amendment?

Yes — the employee has an absolute right to refuse a contract modification. This refusal is NOT misconduct. Consequences: the employer must either abandon the modification or initiate an economic termination (if the modification is economically justified) — the termination is then imputable to the employer. For « personal grounds » modifications, refusal makes the modification impossible.

Is a reflection period required between proposal and signature?

For an economic-grounds modification (art. L1222-6 French Labour Code), the employer must notify the employee by registered mail and grant a 1-month period (15 days in receivership/liquidation). Employee silence equals acceptance. For personal-grounds modifications, no legal period — practice recommends 8 days minimum.

Is CSE (works council) opinion required for an amendment?

No, not for an individual amendment. The CSE is only informed/consulted for collective modifications (restructuring, redundancy plan). For an amendment affecting a single employee, no CSE consultation is required.

How long should an employment amendment be kept?

5 years minimum from contract end (art. L1471-1 French Labour Code, statute of limitations for contract execution action). In practice, 10 years recommended to cover termination and retirement disputes. Certyneo automatically archives 10 years, free of charge.

Is an electronically signed amendment enforceable in labour court?

Yes, without restriction. The eIDAS proof PDF (employee identity, qualified timestamp, SMS OTP) constitutes irrefutable evidence of signature, enforceable before the Labour Court. The French Supreme Court (Cass. soc. 5 June 2019) validated this evidence.

What is a permanent-contract amendment?

The amendment is a legal act that modifies an existing employment contract: position change, salary, working time, work location, mobility or non-compete clause addition. French case law (Cass. soc. 18 December 1990, then confirmed by Cass. soc. 10 July 1996) requires written employee consent for any modification of an essential element of the employment contract. Without a signed amendment, the modification cannot be imposed — it constitutes legitimate grounds for termination on the employer's account. No specific formalism beyond signature of both parties is required.

Why sign a permanent-contract amendment electronically?

Identical legal value

Art. 1366 of the French Civil Code grants electronic writing the same probative force as paper. The French Supreme Court (Cass. soc. 5 June 2019) validated electronic signature for HR acts. No text mandates manuscript signature for an amendment.

Employee consent timestamped

The eIDAS audit trail attests to the EXACT signature date by the employee — critical evidence in case of subsequent dispute. No more debate on the modification effective date: the qualified timestamp is enforceable in labour court.

Secure employer → employee workflow

The employer prepares the amendment + sends it to the employee via secure link. The employee signs from their phone after SMS OTP identity verification. No risk of « proxy signature » by another employee.

5-year archive + HR integration

The French Labour Code (art. L1471-1) mandates 5-year retention for acts related to the contract. Our 10-year archive amply covers this. HRIS integration possible (Lucca, PayFit, Eurécia) to attach the amendment to the employee file.
