How long does a PSE take? The full timeline of a French Plan de Sauvegarde de l'Emploi

When an employer announces a Plan de Sauvegarde de l'Emploi (PSE), the schedule that follows is not left to their discretion: the French Labour Code strictly frames each step, with durations that vary depending on the plan's size and the route chosen. For an employee in scope, understanding this timeline is essential — it dictates the time available to negotiate your individual situation, explore internal mobility, or prepare what comes next.

Order of magnitude: a small PSE via majority agreement can be completed in 2.5 to 3 months. A large unilateral PSE with contestation can stretch to 12 months or more before the first effective departures.

When does a PSE apply?

A PSE is mandatory when two cumulative conditions are met:

• The company employs at least 50 employees;
• The project plans the economic dismissal of at least 10 employees within a 30-day period.

Below these thresholds, the employer can proceed with economic dismissals without a PSE, but must follow a lighter procedure. (Code du travail, articles L1233-3 and L1233-61.)

Two routes: majority agreement or unilateral document

A PSE can take one of these two forms — a choice that strongly determines duration and the degree of administrative oversight.

1. PSE via majority collective agreement — the fast route

The employer negotiates the PSE content with representative trade unions. The agreement must be signed by unions that received at least 50% of the vote in the most recent CSE elections.

Advantages:

• Shorter DREETS deadline: 15 days for validation;
• Administrative review limited to procedural regularity and absence of fraud;
• Possible flexibility on consultation deadlines by agreement;
• Generally calmer social climate.

2. PSE via unilateral document — the long route

The employer drafts the PSE alone after consulting the CSE. The CSE issues an opinion but does not have a veto right. The PSE is then submitted to homologation by the DREETS.

Characteristics:

• Longer DREETS deadline: 21 days for homologation;
• Extended oversight: the DREETS additionally checks the sufficiency of measures against the means of the company and group, and the proportionality of accompanying measures;
• More possibilities for legal challenge before the administrative court;
• Typical case: Ford Blanquefort 2019 — the PSE was rejected once in January 2019 by Direccte, then validated in March after revision.

The official timetable

Step	Duration	Reference
R1: project announcement and 1st CSE meeting	Day 0	L1233-30
CSE consultation	2 to 4 months depending on size	L1233-30
DREETS notification	During or after consultation	L1233-57-3 / -4
DREETS validation (collective agreement)	15 days	L1233-57-4
DREETS homologation (unilateral document)	21 days	L1233-57-3
Individual dismissal notifications	After validation / homologation	L1233-39
Notice period or reclassement leave	1 to 12 months	L1233-71 et seq.

CSE consultation duration scales with plan size

Article L1233-30 of the Code du travail sets the maximum CSE consultation period based on the number of planned dismissals:

• 2 months if the project concerns fewer than 100 dismissals;
• 3 months if the project concerns 100 to 249 dismissals;
• 4 months if the project concerns at least 250 dismissals.

The clock starts from the date of the first CSE meeting ("R1"). At its end, the CSE is deemed consulted even if it hasn't issued an opinion. These deadlines can be extended or shortened by majority agreement.

DREETS deadlines — silence equals approval

Once the DREETS is notified through the digital portal (RUPCO / TéléPSE), it has:

• 15 days to validate a collective agreement (article L1233-57-4);
• 21 days to homologate a unilateral document (article L1233-57-3).

Beyond this deadline, silence equals approval — the PSE is considered validated or homologated. This is one of the rare French administrative procedures where administrative silence has a favourable effect for the employer.

Total estimate by plan size

PSE size	Agreement route (minimum)	Unilateral route (minimum)
< 100 dismissals	~2.5 months	~3 months
100 – 249 dismissals	~3.5 months	~4 months
≥ 250 dismissals	~4.5 months	~5 months

These estimates assume no CSE expert designation and no court challenge. In practice, large PSEs often take 6 to 12 months before effective departures.

What can extend the timeline

Several factors significantly prolong the process:

• CSE expert designation (article L1233-34) — the CSE can designate an independent expert firm. Consultation is suspended pending the report.
• Challenge before the administrative court — possible appeal against the DREETS decision within 2 months of notification. The court rules within 3 months.
• Voluntary / PDV component — if the PSE integrates a voluntary departure plan, the application phase typically extends 3 to 6 months after validation.
• Strong union mobilisation — extended strikes, blocked negotiations. Case examples: Whirlpool Amiens 2018 (one-month strike), Accor 2021 (PSE transformed into PDV after FO mobilisation).
• Reconfiguration after DREETS rejection — case Ford Blanquefort 2019: first Direccte rejection in January, validation only in March after revision.
• Retroactive annulment — case Sanofi Aventis R&D 2024: PSE validated in November 2024 then annulled by the Melun Administrative Court in April 2025 for a discriminatory selection-criteria grid.

What follows validation

Once the PSE is validated or homologated, the schedule remains structured:

Individual notification

The employer notifies each affected employee by registered letter with acknowledgement of receipt. Minimum delay between the preliminary meeting and notification: 7 working days (15 days for senior executives).

Notice period or alternative

Depending on the option offered to the employee:

• Standard notice period: 1 to 3 months depending on seniority and status (collective agreement).
• Reclassement leave: 4 to 12 months, reserved for companies with 1,000 or more employees. The employee remains under contract, paid 65 to 80% of salary (depending on the PSE), with access to an outplacement firm.
• CSP (Contrat de Sécurisation Professionnelle): alternative to notice for companies under 1,000 employees. Duration 12 months, allocation 75% of reference daily salary.

Effective departures

For a large PSE (cf. Sodexo 2024, 2,083 positions), effective departures often spread over 12 to 24 months from validation, in several waves.

For an employee in scope — what to remember

• If the announcement has just been made, count at least 3 months before individual notification.
• For a large plan (≥ 250 dismissals), count 5 to 6 months minimum.
• Before effective departure, add the notice period or reclassement leave (1 to 12 additional months).
• If you're in scope, this time is precious: it lets you negotiate your individual situation, explore internal mobility, or anticipate a professional project.

The OpenRecourse observatory today references 39 plans (PSE, PDV, RCC, GPEC) over the 2013 – 2026 period. Each entry includes a status (signed, in negotiation, annulled) and, when public, the precise timetable.
