Terminating employment in Luxembourg: notice, reasons and severance

Employment in Luxembourg cannot be ended at will, and nothing in a contract can make it so. A contrat à durée indéterminée (CDI, an open-ended contract) may be terminated by the employer only on real and serious grounds, motifs réels et sérieux, and only through a written process with fixed dates inside it. An employer used to two weeks’ notice, or to none, should expect months between the decision and the final payslip.

There are two families of grounds: reasons inherent in the person of the employee, covering aptitude, performance and conduct, and reasons based on the operating needs of the undertaking, meaning restructuring or economic difficulty. A dismissal resting on neither is exposed, and the reasons must be capable of being stated with precision, because the employee can compel the employer to state them.

Form carries as much weight as substance. A dismissal announced in a meeting and never confirmed in writing starts none of the clocks that follow, and an oral dismissal is abusive in itself. An employee who resigns is held to the same standard, in writing, with notice of their own.

Probation works differently. During a période d’essai (trial period) either side may end the contract on short notice calculated from the agreed length of the trial, and the first fortnight is closed to termination except for serious misconduct. Everything below concerns the ordinary contract once probation has passed; probation drafting sits in our guide to Luxembourg employment contracts.

Statutory notice on dismissal is two months for an employee with less than five years’ service, four months from five to under ten years, and six months at ten years or more, measured by seniority on the date notice is given. An employee who resigns gives half of each figure, so one, two or three months. These are floors in the Code du travail; a contract may improve on them but not cut them.

Then comes the detail foreign employers almost always miss. Notice does not run from the date of the letter. Posted before the 15th of the month, it begins on the 15th of that same month; posted on or after the 15th, it begins on the 1st of the following month. The postmark governs, not the date typed on the page and not the day the envelope lands, and the same rule applies to a resignation.

Real elapsed time from decision to last day is therefore the statutory notice plus up to a fortnight. A letter posted on 16 March to an employee with six years’ service starts a four-month notice on 1 April, and the employment ends on 31 July, four and a half months after the envelope went out. Salary, employer contributions and leave accrual run throughout, so build the exit budget on the longer period.

Once notice starts it is fixed, and illness or leave falling inside it does not extend it. An employer may release the employee from working the notice, but that shortens nothing for seniority or severance, and Luxembourg provides a statutory job-search leave during notice, so assume some paid absence.

A dismissal with notice is notified by registered letter, or handed over against the employee’s signature, in a language the employee actually understands. Luxembourg names no compulsory language; the standard is comprehension, so a letter to someone who works in English is written in English even though the declarations around it are made in French or German. The letter itself need not state the reasons.

Employers with 150 or more employees must hold a preliminary meeting, the entretien préalable, before any dismissal outside probation, whether with notice or with immediate effect. The employee is convened by registered letter with acknowledgement of receipt, stating the object, date, time and place of the meeting and the right to be assisted by a colleague or a trade union representative. The meeting is held no earlier than the second working day after the convocation goes out, and the dismissal letter follows between the day after the meeting and eight days after it. Skipping the procedure costs up to one month’s salary in compensation for procedural irregularity.

Below 150 employees there is no such obligation, which covers most single hires and small teams. A lower threshold does bite: an employer with 15 or more employees must notify the Comité de conjoncture, on the official form, of every dismissal on grounds not inherent in the person of the employee. Both thresholds attach to the employing undertaking, so an exit plan starts with which entity is counting heads.

An employee dismissed with notice may demand the reasons in writing, and the employer then has one month to answer. The request must reach the employer by registered letter within one month of the dismissal being notified, and it may be sent by a lawyer or a trade union official on the employee’s behalf. The employer replies within one month of receiving it, again by registered letter, setting out precise and concrete reasons.

Missing that reply is the most expensive administrative error in Luxembourg termination. Failure to answer in time makes the dismissal automatically abusive, whatever the merits of the decision, and the employee moves straight to damages. A reply offering a general formula such as loss of confidence, with no facts attached, is barely better, because the reasons must be concrete enough for a tribunal to test.

Note that the two months stack: the employee has a month to ask and the employer a month to answer, so a request can land well after the notice period has started running. For a dismissal with immediate effect the position is different, because the reasons must already be set out precisely in the dismissal letter.

Severance in Luxembourg, the indemnité de départ, starts only at five years’ service, and nothing is due below that. It is payable on dismissal with notice, never on resignation and never where the dismissal is for serious misconduct. Seniority is assessed at the expiry of the notice period, even where the employee was released from working it, so someone at four years and nine months on the date of the letter can still cross the threshold before the contract ends.

• Less than 5 years: no severance
• 5 to under 10 years: 1 month’s salary
• 10 to under 15 years: 2 months’ salary
• 15 to under 20 years: 3 months’ salary
• 20 to under 25 years: 6 months’ salary
• 25 to under 30 years: 9 months’ salary
• 30 years and above: 12 months’ salary

The payment is calculated on the average gross salary of the twelve months preceding the dismissal and falls due at the end of the notice period. An employer cannot shrink it with short notice, because seniority is then assessed as though the legal notice had been given. Employers with fewer than 20 employees may elect to extend the notice period instead of paying, on a scale running from five months in place of one month’s severance up to eighteen months at thirty years.

On tax, be careful with what you read. The indemnité de départ is treated favourably for income tax, but the exemption is subject to statutory limits and is not unlimited. Confirm the position for the specific payment with the Administration des contributions directes (ACD) before promising a net figure.

Dismissal for faute grave ends the contract immediately, with no notice and no severance, and the test is demanding. The fault must be grave enough to make it immediately and definitively impossible to maintain the working relationship, judged against the employee’s record, training and circumstances. The employer has one month from the day it learned of the facts to act, and the letter must set out those facts precisely: vague wording is fatal and cannot be repaired later. Pending the decision the employer may suspend the employee, a mise à pied, on full salary and benefits.

Some employees cannot be dismissed at all for a period, and sick leave is the one that catches employers out. An employee on certified incapacity is protected for up to 26 weeks from the onset: the employer may not serve notice, may not dismiss for serious misconduct, and may not even convene the employee to a preliminary meeting. The protection depends on the employee having met the notification and certificate duties, and does not apply where the dismissal was notified before the employer knew of the incapacity. The detail sits in our guide to Luxembourg sick leave rules.

Pregnancy, maternity and parental leave carry protections of their own, and a dismissal in breach is null rather than merely abusive, which opens the door to reinstatement. Staff delegates are protected throughout their mandate and for six months after it, and for them even the convocation to a preliminary meeting is void. Check status before choosing a date.

An employee who considers the dismissal abusive has three months to bring a claim before the Tribunal du travail. The period runs from the earliest of four events: notification of an immediate dismissal, notification where no reasons were requested, receipt of the employer’s written reasons, or the date by which the employer should have replied. A written claim sent to the employer interrupts it and opens a fresh period of a year, so a file is not safely closed on the three-month anniversary.

Where a dismissal is held abusive the tribunal awards damages: material loss, being earnings lost over a reference period the tribunal fixes, less unemployment benefit received and conditional on the employee showing genuine efforts to find work, and moral damages for the distress of losing the job. Reinstatement is not the ordinary remedy and belongs to the cases where a dismissal is null. The contrast with at-will practice is in our note on US and Luxembourg termination rules.

Through an exit, an Employer of Record runs the employer-side mechanics while the client makes the commercial decision. Employer of Record Luxembourg is registered to employ in Luxembourg and is the legal employer, so the letter is drafted in a language the employee understands, posted by registered mail against the rule of the 15th, the reply window is diarised, and any Comité de conjoncture notification is filed.

The closing work is payroll and paperwork. Final pay covers salary to the end of the notice period, untaken annual leave and the indemnité de départ where seniority reaches five years, with contributions settled on each. An exit declaration closes the record at the Centre commun de la sécurité sociale (CCSS). Costing an exit before the hire beats costing it after the decision, so send us the seniority and the salary.
