Forms of Employment Contract Termination in Luxembourg

1. Overview — the termination methods

The following table provides a concise overview of the four main ways of terminating an open-ended employment contract (CDI):

These four methods are supplemented by specific rules for fixed-term contracts (early termination), the probationary period and automatic termination, covered in section 6.

2. Dismissal with notice — CDI (Art. L.124-3)

The employer may terminate an open-ended contract by giving notice calculated according to the employee's seniority within the company. Notification must be made by registered letter, which takes effect from the third working day following the date of dispatch (Art. L.124-3).

Waiver of notice period (Art. L.124-9)

The employer may decide to release the employee from the obligation to work during the notice period. This waiver does not alter the end date of the contract or the employee's rights: the employee continues to receive full salary, benefits and accrued leave until the end of the notice period. The waiver is granted unilaterally by the employer; no agreement from the employee is required.

3. Dismissal for serious misconduct (Art. L.124-10)

Dismissal for serious misconduct allows the employer to terminate the contract without notice and without severance pay, where the employee's behaviour or actions make it immediately and definitively impossible to maintain the employment relationship. This route is reserved for the most serious situations; it cannot be used routinely to bypass the ordinary dismissal procedure.

Formal requirements

Notification of dismissal for serious misconduct must be made by registered letter setting out the precise facts complained of (Art. L.124-10). The statement of facts is a condition of validity: a vague letter or one that merely mentions "serious misconduct" without detail exposes the employer to reclassification of the termination as wrongful dismissal.

What the law expressly excludes

A medically confirmed incapacity for work does not constitute serious misconduct (Art. L.124-10). An employee declared unfit by the occupational health physician cannot therefore be dismissed for serious misconduct solely on account of that incapacity: the vocational reclassification procedure must be initiated instead.

4. Employee resignation (Art. L.124-4)

An employee may terminate an open-ended contract at any time by notifying the employer by registered letter (Art. L.124-4). Resignation is a unilateral act: it is not subject to any substantive condition and does not require the employer's agreement.

Notice period applicable to the employee

A resigning employee must observe a notice period equal to half the period the employer would have to give in the event of dismissal, calculated on the same seniority basis:

• seniority of less than 5 years: notice of 1 month;
• seniority between 5 and less than 10 years: notice of 2 months;
• seniority of 10 years and over: notice of 3 months.

5. Mutual termination agreement (Art. L.124-13)

The employer and the employee may agree together to end their employment relationship, whether the contract is fixed-term or open-ended. Mutual termination offers flexibility that the other termination methods do not allow: the parties freely determine the end date, the financial arrangements and the departure conditions.

Conditions for validity

To be valid, the termination agreement must be recorded in writing, drawn up in two original copies and signed by both parties (Art. L.124-13). The absence of a written document renders the agreement unenforceable: the termination would then be analysed as a dismissal or a resignation depending on the circumstances.

Mutual termination does not in principle give entitlement to unemployment benefits in Luxembourg, unless the agreement expressly includes financial clauses enabling the employee to assert their rights. This point must be clearly addressed during negotiations.

6. Special cases — fixed-term contracts, probationary period and automatic termination

Early termination of a fixed-term contract (Art. L.122-13)

A fixed-term contract cannot in principle be terminated before its end date. Only serious misconduct — within the meaning of Art. L.124-10 — or mutual agreement between the parties allows a fixed-term contract to be terminated early (Art. L.122-13).

If the employer terminates the fixed-term contract without serious misconduct, they may be ordered to pay damages corresponding to the salaries that would have been due until the end of the contract, up to a ceiling equivalent to the statutory notice periods. Conversely, if it is the employee who terminates without serious misconduct, they may be required to compensate the employer for the resulting loss.

Termination during the probationary period (Art. L.121-5)

During the probationary period, either party may end the contract under simplified rules. However, the contract cannot be terminated unilaterally during the minimum two-week period, except for serious misconduct (Art. L.121-5). After this protected period, termination may occur with a reduced notice period, the length of which is set by law depending on the total agreed duration of the probationary period.

Automatic termination (Art. L.125-1)

The employment contract terminates automatically, without the parties having to complete any specific formality, in two situations provided by law:

• the death of the employee;
• the cessation of the employer's business as a result of the employer's death, physical incapacity or declaration of bankruptcy (Art. L.125-1).
