The AER CS (rematerialised employer attestation) is the document that will replace the AEM (Attestation Employeur Mensuelle, monthly employer attestation) of intermittents du spectacle. Its full name — attestation employeur rematérialisée cinéma spectacle — translates as “rematerialised employer attestation, cinema and live performance”. The difference from the AEM? It is no longer your employer who writes it, but France Travail (formerly Pôle emploi), from the DSN (nominative social declaration) the employer already declares.
The AER CS, in plain terms
Until now, after each shoot, your employer produced an AEM (monthly employer attestation) to declare your hours to France Travail. With the reform, they no longer send anything but their DSN (nominative social declaration), and it is France Travail that generates the attestation from that data. This document is called the AER CS, sometimes written “AE CS” (employer attestation, cinema and live performance).
Who produces it, and when you receive it
France Travail issues the AER CS, from the employer’s DSN. You receive it per employer and per month, like the AEM. For a contract running over several months, a single AER CS is issued at the end.
What it contains
The same information as the AEM, and as your payslip:
- the name of the structure employing you;
- the number of hours or cachets;
- the gross pay;
- the period worked.
Worth checking every time: these details must match your signed timesheet and your payslip. Because the source is now the DSN, a declaration error by the employer feeds straight into your rights.
AER CS vs AEM: what really changes
- Who writes it: the AEM came from the employer; the AER CS comes from France Travail.
- What it is based on: the AER CS is generated from the DSN, a single declaration that replaces the DSN + AEM pair.
- For your 507 hours: nothing changes in substance, you still need 507 hours over 12 months. Only the source of the proof changes.
And in practice, for you
The rollout is gradual: pilot since 2025, transition in 2026, generalisation targeted for early 2027. Depending on your employer, you therefore still receive AEMs, or already attestations produced from the DSN (sometimes marked “specimen” during the pilot phase). For the full timeline, the impact on the 507-hour counter and the pitfalls of the transition, see the guide: The end of the AEM: the DSN / AER CS reform.
On the tool side: Intermittor currently imports the AEM PDF to keep your 507-hour counter up to date, and will be updated to read the AER CS as soon as the format is in circulation. You import whichever document you receive, whether it is called AEM or AER CS, and the tracking carries on without changing any of your habits.
Frequently asked questions
AER CS or AE CS, what is the difference?
None: it is the same document, referred to by two acronyms. “AER CS” stands for attestation employeur rematérialisée cinéma spectacle — the rematerialised employer attestation, cinema and live performance — and you will also see “AE CS” (attestation employeur cinéma spectacle). Either way, it is the attestation produced by France Travail from the DSN that replaces the AEM.
Who produces the AER CS?
France Travail, from the DSN declared by your employer. That is the big difference from the AEM, which was written and sent by the employer themselves. You receive one AER CS per employer and per month.
Does the AER CS replace the AEM?
Yes, gradually. The rollout happens in waves, employer by employer: pilot since 2025, transition in 2026, generalisation targeted for early 2027. As long as your employer has not switched to the DSN, you keep receiving your usual AEMs.
What should you check on an AER CS?
The name of the structure employing you, the number of hours or cachets, the gross pay and the period worked. Cross-check against your signed timesheet and your payslip. Because the information comes from the DSN, a declaration error by the employer directly affects your rights: if a period is missing, contact the employer so they correct their declaration.
Key takeaways
- AER CS = AE CS: the attestation produced by France Travail from the DSN that replaces the AEM.
- Same content as an AEM (employer, hours or cachets, gross pay, period), to be checked in the same way.
- Your 507 hours do not change; only the source of the proof changes.
