Special Protection Against Dismissal in Luxembourg

1. Protection of staff delegates: an absolute prohibition

Full and alternate members of staff delegations, together with the health and safety delegate, benefit from a public-policy protection throughout the duration of their mandate. The employer may neither notify them of a dismissal nor summon them to a pre-dismissal interview — and this prohibition applies even in cases of serious misconduct (Art. L.415-10).

Any act in breach of this prohibition is struck with absolute nullity. An employer who disregards it incurs civil and criminal liability. The protection is designed to guarantee the independence of staff representatives in the exercise of their mandate, shielding them from any pressure or disguised retaliatory dismissal.

2. Serious misconduct by a delegate: precautionary suspension

Where a staff delegate commits serious misconduct justifying immediate exclusion from the workplace, the employer has one strictly regulated alternative: they may notify a precautionary suspension. The delegate is then removed from the workplace, but their salary is maintained in full for three months (Art. L.415-10).

During that period, the employer must refer the matter to the competent labour court in order to obtain authorisation to proceed with the dismissal. It is the judge — not the employer alone — who assesses whether the serious misconduct is sufficiently established to justify termination. Without a favourable court ruling, the delegate cannot be dismissed.

3. Extension of protection: former delegates and candidates

Protection does not lapse when the mandate ends. Former delegates enjoy identical protection for the six months following the expiry of their mandate. This extension is designed to prevent deferred retaliatory dismissals, served as soon as the mandate ends in an attempt to circumvent the in-mandate protection (Art. L.415-11).

Candidates in staff delegation elections are also protected: protection takes effect from the date the candidacy is officially submitted and continues for the three months following the close of the election (Art. L.415-11).

4. Protection of pregnant employees and new mothers

The employer may not notify either the termination of the contract or the summons to a pre-dismissal interview during two cumulative periods (Art. L.337-1):

During a medically confirmed pregnancy — as soon as the pregnancy is established by medical certificate, the protection takes effect, regardless of whether the employer has been informed beforehand. In practice, the employee has every interest in informing their employer as early as possible in order to make the protection enforceable against them.

During the twelve weeks following delivery — the protection continues automatically after the birth, irrespective of the length of maternity leave actually taken.

Any dismissal or summons notified in breach of this protection is void and of no effect. The employee may apply to the labour court president sitting in urgent proceedings for it to be set aside, within an urgent deadline of fifteen days from notification of the termination.

Exception: serious misconduct and precautionary suspension

In the event of serious misconduct, the employer may impose an immediate precautionary suspension on the pregnant employee pending the decision of the labour court (Art. L.337-1). The mechanism mirrors that applicable to staff delegates: it is the judge who authorises or refuses the dismissal, and the employee retains their salary throughout the proceedings.

5. Protection of employees undergoing professional redeployment

For employers with at least twenty-five employees, a professional redeployment obligation arises when an employee is found incapable of occupying their last position (Art. L.551-2). Throughout the redeployment procedure and beyond, the employee enjoys enhanced protection against dismissal.

Any dismissal and any summons to a pre-dismissal interview notified from the time the Joint Commission is seised — the bipartite body responsible for ruling on redeployment — until the expiry of the twelfth month following the mandatory redeployment decision are struck with absolute nullity. This double boundary (start of proceedings + 12 months after the decision) gives the employee the time needed to actually take up the redeployment post.

Two exceptions limit this protection. It does not apply to the natural expiry of a fixed-term contract: the protection does not convert a fixed-term contract into an open-ended one. Nor does it apply to a termination for serious misconduct attributable to the employee — provided, however, that the employer follows the judicial route in the same manner as for staff delegates (Art. L.551-2).

6. Other protections, remedies and urgent deadlines

Incapacity to work due to illness or accident

The employer may not notify either the termination of the employment contract or the summons to a pre-dismissal interview during a period of incapacity to work of a maximum of twenty-six weeks running from the onset of that incapacity (Art. L.121-6). This protection is conditional: the employee must have notified the employer of their incapacity and provided a medical certificate within the statutory deadlines. Without that, the protection cannot be relied upon.

Prohibition of retaliation

An employer is prohibited from notifying the termination of an employment contract or a summons to a pre-dismissal interview by way of retaliation following a complaint or legal action brought by the employee to enforce their rights under the Labour Code (Art. L.010-2). This protection applies to all employees regardless of status or length of service, and covers in particular reports made to the Labour and Mines Inspectorate.

Remedies in the event of nullity: retention and reinstatement

Where a dismissal is declared void by reason of a special protection regime, the employee may apply to the president of the labour court sitting in urgent proceedings to obtain (Art. L.124-12): either retention in the business during the proceedings, or reinstatement if the void dismissal has already taken practical effect. These remedies are distinct from mere compensation for unfair dismissal: nullity opens a right to the continuation of the employment relationship, not merely to damages.
