Pregnancy and maternity leave

Women who are pregnant or have just given birth benefit from a certain number of advantages in the workplace, one of which is maternity leave. These advantages aim to protect the health of the women concerned and also allow them to devote themselves fully to their child after the birth.

Pregnant women have the right to:

  • protection against dismissal as from the beginning of the pregnancy;
  • special protection in terms of health and safety if they occupy a position involving specific risks;
  • protection againt risks related to night work;
  • exemption from work to allow them to attend their antenatal check-ups;
  • several weeks of leave before and after the birth;
  • a special organisation of their working hours if they are breastfeeding.

Who is concerned

Most of the administrative procedures related to pregnancy are mainly carried out by the pregnant woman working in Luxembourg as:

  • an employee;
  • a self-employed worker;
  • an apprentice.

The employer, for his part, must grant her certain rights and respect certain specific formalities before, during and after the maternity leave.

Women with the self-employed worker status in Luxembourg also benefit from maternity leave. They only have the obligation to inform the health insurance fund concerned.

How to proceed


When an employee is pregnant and has duly informed her employer, she benefits from a series of rights and special protection measures.


During a job interview, pregnant women are not required to inform their prospective employer of their pregnancy.

If the employer asks the question, they do not have to disclose their pregnancy. Pregnancy forms part of the private sphere.

If a pregnant woman is hired, maternity protection only applies from the moment she informs her employer of her condition.

Informing the employer and the health insurance fund of the pregnancy

Employees are protected during the full duration of the pregnancy, from the moment the employer has been informed of their condition.

Upon the employer's request or in case of a need for special protection (e.g.: hazardous work, night work, etc.), the employer can be given a medical certificate attesting to the pregnancy. In this case, the employee must submit the certificate:

  • either by registered letter with acknowledgment of receipt;
  • by giving it in person, in which case the employer must acknowledge receipt on the copy of the certificate;
  • by fax or email, provided the certificate is transmitted in a clean and legible format.

The employee must submit a recent medical certificate (issued 12 weeks before the expected date of delivery at the earliest) stating the expected date of delivery to the health insurance fund and her employer within 12 weeks of the expected date of delivery.

Trial period

Employers may not terminate the employee's contract during the trial period if they have been duly informed of the pregnancy.

If an employee on a permanent employment contract becomes pregnant during her trial period, the trial period is suspended from the day the employee submits a medical certificate to her employer confirming the pregnancy.

The remaining time of the trial period will start running at the end of the period of protection against dismissal (i.e. 12 weeks after the delivery).

In the case of a fixed-term employment contract, there is no suspension of the trial period or renewal of the fixed-term contract, which expires normally at the end of the term initially foreseen.

Protection of pregnant women against dismissal

Employers who have been duly informed of the pregnancy may not dismiss with notice an employee whose pregnancy has been confirmed by a medical practitioner. This ban on dismissal is valid throughout the duration of the pregnancy and for another 12 weeks after the birth.

If an employee is dismissed before her pregnancy has been confirmed by a medical practitioner, she has 8 days from the notification of dismissal to provide her employer with a medical certificate as proof of her pregnancy.

The employer must then annul the decision to dismiss with the employee's consent. If the employer refuses to annul the dismissal, the employee has 15 days following the termination of the contract to file a claim to the labour tribunal in order to demand that the dismissal be declared null and void.

In the event of cessation of business, the termination of employment is not declared null and void.

However, a pregnant employee's contract may be terminated in case of serious misconduct. Employers can request the employee's immediate suspension pending the decision of the labour tribunal, but they cannot send the actual letter of dismissal on their own initiative. They have to file a request with the labour tribunal in order to be authorised to terminate the employment contract. The tribunal will assess the gravity of the misconduct and decide whether or not to validate the immediate suspension and thus terminate the employee's employment contract.

In the event of an irregular dismissal without a suspension that occurred in the conditions stated above, the president of the tribunal will order the reinstatement of the salaried woman in the business.

If the dismissed pregnant woman has not requested the nullity of the dismissal within 15 days of the termination of the contract, she can take legal action and claim damages for wrongful dismissal.

Antenatal check-ups

The employer must grant the exemption from work without loss of remuneration to allow pregnant women to attend their antenatal check-ups.

Protection of pregnant or breastfeeding women

Employers cannot request overtime work from pregnant or breastfeeding women if they do not wish to work overtime. Moreover, they benefit from special protection against hazardous jobs and night work.

Protection against work which is hazardous to health and safety

Employers must take measures to protect pregnant and breastfeeding women from risks related to hazardous work.

They have to inform all their female employees as well as the joint works committee, or, failing this, the staff delegation and, where applicable, the equal opportunities officer:

  • of the list of tasks that pregnant or breastfeeding women are not required to perform;
  • and of the measures taken to avoid:
    • any risks to the health and safety of these women;
    • any possible impact on the pregnancy or breastfeeding.
It should be noted that joint works committees (also "joint works councils") will cease to exist after the social elections which will take place after 1 August 2016. As from these elections, the tasks and duties assigned to joint works committees will be transferred to the staff delegation. The staff delegation will be set up in companies which employed at least 150 staff during the 12 months prior to the first day of the announcement of elections.

Until these elections, the joint works committees currently in place will continue to carry out their tasks.

These tasks are divided into 2 categories:

  • category 1 (activities that are likely to present a risk of exposure to certain agents, procedures or working conditions):
    • tasks such as lifting loads of over 5 kgs;
    • tasks involving a risk of falling or slipping;
    • tasks requiring the employee to constantly be in a crouched or bent position.
  • category 2 (activities which present a risk of exposure to certain agents or working conditions and put in danger the health and safety of employees):
    • tasks exposing the woman to chemicals such as lead;
    • tasks exposing the woman to biological agents such as toxoplasmosis or the rubella virus.

With regard to tasks in category 1, the employer must assess whether there is a risk to the employee's health and safety as well as possible repercussions on the pregnancy or breastfeeding. Where such risks have been detected by the employer, he must, in accordance with the occupational health practitioner's recommendation:

  • either provisionally change the working conditions or hours to eliminate the risk;
  • or, if it is technically or objectively impossible, transfer the employee to another workplace and maintain her current salary level;
  • or, if the transfer is technically or objectively impossible, exempt the employee from work during the whole period which is necessary to protect her health and safety.

With regard to tasks in category 2, the employer, together with the occupational health practitioner, must determine the activities which pose a threat to the health and safety of pregnant or breastfeeding women. If these activities exist within the company, the employer must, in accordance with the occupational health practitioner's recommendation:

  • either immediately transfer the employee to another position with the same salary as in her former position;
  • or, if this transfer is not possible, exempt the employee from work during the whole period necessary to protect her health or safety.

Should the employee be exempt from work, the employer can stop paying her salary. The employer submits the recommendation from the relevant occupational health practitioner to the health insurance fund which, in return, will pay the employee a financial compensation equivalent to her salary.

The following documents are required:
  • the original recommendation (pink sheet) from the occupational health practitioner;
  • a copy of the employer's request for advice;
  • a copy of the medical certificate stating the expected date of delivery for the National Health Fund (CNS).

Protection against night work

Pregnant or breastfeeding women may request exemption from night work (between 22.00 and 6.00) from their employer until their child's first birthday:

  • either by registered letter with acknowledgment of receipt;
  • or by having the employer sign a copy of the request as proof of receipt.

The employer must contact the occupational health practitioner within 8 days of receiving the request.

The occupational health practitioner will then determine whether the health and safety of the pregnant or breastfeeding woman are at risk and inform the employee and the employer of his decision within 15 days.

Employers are required to comply with the recommendations issued by the occupational health practitioner.

If the occupational health practitioner believes there is a risk, the employer must:

  • either transfer the employee to a day time position;
  • or, if this transfer is technically and/or objectively impossible, exempt the employee from work during the whole period which is necessary to protect her health and safety in agreement with the occupational health practitioner.

Should the employee be transferred to a day time position, the employer must continue to pay her the same salary as before. The employer forwards the approval from the relevant occupational health practitioner to the health insurance fund in order to be reimbursed the difference between the salary for day time work and the salary for the night work carried out by the employee before her pregnancy.

Should the employee be exempt from work, the employer stops paying her salary. He submits the approval from the relevant occupational health practitioner to the CNS who, in return, will pay the employee financial benefits equivalent to her salary.

Maternity leave

Conditions for the granting and amount of financial maternity benefits

In order to be granted maternity benefits during maternity leave, the employee or self-employed worker must have been affiliated with the mandatory sickness and maternity insurance fund for at least 6 months during the 12 months prior to the maternity leave.

Maternity benefits are paid by the health insurance fund during antenatal and postnatal leave. In principle, maternity benefits amount to:

  • for a salaried worker:
    • the highest salary received during the 3 months prior to the maternity leave;
    • where applicable, the average amount of complementary and accessory benefits received during the 12 months preceding the month prior to the start of the maternity leave;
  • for a self-employed worker: the contribution base in force at the time the maternity leave is taken.

Financial maternity benefits cannot be:

Financial maternity benefits cannot be cumulated with sickness benefits nor any other professional income.

Antenatal leave

Maternity leave starts 8 weeks before the expected date of delivery.

If the birth occurs before the expected date of delivery, the days of antenatal leave not taken are added to the postnatal leave (however, the total duration of maternity leave may not exceed 20 weeks).

If the birth occurs after the expected date of delivery, the antenatal leave is extended until the effective date of birth, without reducing the duration of the postnatal leave, which remains 8 weeks.

An antenatal maternity leave calculation form is available on the CNS website.

Postnatal leave

Maternity leave continues for 12 weeks after the actual date of delivery.

The employer's signature on the copies of the certificate are valid as proof of receipt.

For example:

The expected date of delivery is 4 May, but the actual delivery takes place on 2 May, i.e. 2 days before the due date:

  • the medical certificate stating the expected date of delivery can be issued as from 8 February, i.e. within the 12 last weeks of pregnancy;
  • antenatal leave starts on 9 March, i.e. 8 weeks (56 calendar days) before the expected date of delivery;
  • postnatal leave ends on 26 July, i.e. 84 calendar days from the actual date of delivery + 2 days deferred from antenatal leave.

The father will be granted 2 days (or more, depending on the statutes/collective agreement in force in the company) of extraordinary leave for reasons of childbirth.

Impact of the leave on the working relationship

Maternity leave is considered as an effective period of work.

Therefore, the employer must:

  • take maternity leave into consideration when calculating the days of annual leave. The days of annual leave not taken by the employee before to the start of the maternity leave can be deferred within the legal deadlines (until 31 March of the following year);
  • take into account the period of maternity leave when calculating seniority and related rights;
  • keep the employee's position open while she is on maternity leave, or keep open an equivalent position corresponding to her qualifications and with a salary at least equivalent to her previous one;
  • maintain the advantages acquired by the employee prior to her maternity leave;
  • allow her to benefit from any improvements in working conditions introduced during her maternity leave.

During maternity leave, the employer must not deregister his employee from the Joint Social Security Centre (Centre commun de la sécurité sociale - CCSS).

But the employer has to:

  • suspend salary payments throughout the period of leave. The salary slips and declarations to the CCSS should therefore show a salary of zero (EUR 0). Benefits in kind (company car, lunch vouchers, etc.) can also be suspended during maternity leave;
  • declare the absence of the employee to the CCSS in the monthly sick leave declarations.

The health insurance fund collects the information required from the CNS in order to pay out the maternity benefits due.

Return to work

Breastfeeding breaks

Any employee returning to work after the maternity leave must be granted breastfeeding breaks by the employer upon request.

The breaks for breastfeeding can be taken as follows:

  • either in 2 periods of 45 minutes, one at the beginning and one at the end of the employee's normal working day;
  • or in a single 90-minute period when:
    • the working day is interrupted by a one-hour break only, and/or;
    • the woman cannot breastfeed her child at a location close to the workplace.

Breastfeeding breaks must be considered as working time and paid accordingly.

The employer can ask the breastfeeding employee to provide a medical certificate as proof of breastfeeding.

Parental leave

At the end of the maternity leave, both parents are entitled to a part-time or full-time parental leave.

Termination of the working relationship

Resignation of the employee

If the employee does not wish to return to work at the end of her maternity leave in order to be with her child, she can resign without notice without having to pay a termination fee for not respecting a notice period

Moreover, she may assert her right to priority for re-employment for a period of one year.

Resignation without notice is only possible in the event where the employee decides to give up her job in order to fully and exclusively devote herself to the education of the child.

Resignation without notice is not possible for women who simply wish to change employer at the end of their maternity leave.
