There is no general exclusion based on the size of the enterprise. However, the LC provides for exemptions from some procedural requirement for enterprises employing less than 11 workers in particular with respect to sanctions in the event of non compliance with dismissal (procedural and substantive)requirements. See art. 1235-5 LC and art. 1235-14 LC (on collective dismissal).
In addition, employees' representatives ("délégués du personnel") who shall be consulted in the event of collective dismissal must be elected only in companies employing at least 11 workers.

The employment relationship of those categories is governed by public law regulations.

The figure refers to the percentage of employee of total number of employee with a contract of limited duration (= temporary job).
Eurostat data are based on the following definition:
"A job may be considered temporary if employer and employee agree that its end is determined by objective conditions such as a specific date, the completion of a task or the return of another employee who has been temporarily replaced (usually stated in a work contract of limited duration). Typical cases are: (a) persons with seasonal employment; (b) persons engaged by an agency or employment exchange and hired to a third party to perform a specific task (unless there is a written work contract of unlimited duration); (c) persons with specific training contracts."

For failure to adopt a mandatory social plan, compensation awarded by the judge cannot be less than the last 12 month's wages (art. L1235-11 LC).

(In addition, depending on the size of the company, the following measures can be mandatory: "reclassification leave" (congé de reclassement), "individual reclassification programme" (convention de reclassement personnalisée), "revitilization of the labour market area" (revitalisation des bassins d'emploi): art. 1233-65 to L 1233-90 LC).

Art. L 1234-9 LC: right to severance pay after a tenure of at least 1 year without interruption, except in case of serious misconduct.
The calculation modalities are determined by art. R 1234-2 LC:
The statutory minimum is 1/5 of monthly wages per year of service.
For employees with more than 10 years of service, 2/15 of the monthly wages multiplied by the number of years of service beyond 10 years should be added.

Ex:
Tenure of 1 year: 1/5 x 1 = 0.2
Tenure of 20 years: (1/5 x 20) + (2/15 x 10) = 5.33

No specific redundancy payment. Severance pay covers economic (individual and collective) dismissals (Art. L 1234-9 LC).

See art. L 1235-3 LC.

In addition, when the dismissal is justified by a serious and genuine cause but the employer fails to observe the prescribed procedure for individual dismissals, compensation awarded by the judge cannot exceed one month's wages (art. L 1235-2 LC).

Art. L 1235-3 LC :
The judge can prescribe reinstatement in case of absence of a serious and genuine cause.
