A close relative hospitalized in an emergency, a feverish child to look after, a sudden death in the family: these situations do not give warning. When they occur, the employee must react quickly, inform their employer, and provide proof.
The difficulty is that the Labor Code and collective agreements do not treat all these cases in the same way. Knowing which leave to invoke, what document to produce, and within what timeframe changes the situation between a protected absence and an unjustified absence.
The concrete risks for an employee in case of unjustified absence
Before discussing procedures, it is important to understand the stakes. An absence not covered by a valid justification can lead to a salary deduction from the very first day. The employer does not need to wait several days to take action.
If the absence continues without news, disciplinary procedures may be initiated. Depending on the applicable collective agreement, three days of unjustified absence may sometimes justify a dismissal for serious misconduct. The employee then loses their notice pay.
This risk explains why the speed of notification is as important as the reason itself. Even in an emergency, a simple call or SMS to their supervisor on the same day already partially protects the employee. The formal justification can follow in the coming days, but the first alert should not wait.
Understanding the procedures related to an absence for compelling family reasons allows for anticipating these situations before they escalate.
Leave for family reasons: distinguishing the provisions according to the situation
You may have noticed that the terms “family leave,” “leave for family events,” and “leave for compelling reasons” are often confused? This ambiguity creates real errors in requests made to the employer.
Leave for family events (short leave)
This provision covers predictable or identifiable events: marriage, civil partnership, death of a close relative, birth or adoption of a child. The duration varies according to the relationship and the event. The death of a spouse or child grants a longer right than the death of an uncle.
The employee retains their salary during this absence. The expected justification is an official document: death certificate, birth certificate, marriage certificate.
Leave for compelling reasons
This leave responds to the unexpected: sudden illness of a child, accident of a relative, serious damage to the home making the employee’s presence essential. The main characteristic is urgency, which makes absence from work unavoidable.
In Belgium, this leave is capped at ten days per year for full-time employees. These days are generally unpaid, unless a more favorable provision is provided by the collective agreement or a company agreement.
In France, the Labor Code does not provide for a specific leave called “compelling reasons” with a defined quota of days. The employee relies on leave for family events, parental leave (in case of a child’s serious illness), or standard paid leave days.
Accepted justifications by the employer: what really works
The type of document to be provided directly depends on the reason invoked. Here are the most common justifications and their scope:
- Medical certificate: mandatory in case of a sick child or hospitalization of a relative. It must mention the necessity of the parent’s or accompanying person’s presence, not just the patient’s diagnosis.
- Death certificate or obituary notice: for leave related to a death, this is the most direct document. The employer may also accept a certificate from the town hall.
- Affidavit: in certain emergency situations (water damage, domestic disaster), the employer may accept a written statement from the employee, later supplemented by a report or an intervention invoice.
- Court or administrative summons: if the absence is related to a legal obligation concerning a family member (guardianship hearing, appearance), the summons itself serves as justification.
A often overlooked point: the justification must be submitted within the timeframe set by the internal regulations. Some companies require submission within 48 hours. Exceeding this deadline, even with a legitimate reason, can reclassify the absence as unjustified on the payslip.
Notifying the employer: the right method at the right time
Oral notification (phone, SMS) on the same day is the priority. The formal written notice should follow, ideally within 24 hours. Why this order? Because the employer needs to be able to reorganize work, and case law takes the notification period into account to assess the employee’s good faith.
An email sent to the hierarchical supervisor and copied to the human resources department constitutes the best written record. Include three elements:
- The reason for the absence (without going into confidential medical details).
- The estimated duration, even if approximate.
- The attached justification or the date it will be provided.
Never transmit detailed medical data to your employer. A medical certificate stating the necessity of your presence with a relative is sufficient. The exact diagnosis is subject to medical confidentiality.
Collective agreement and company agreement: check before requesting
The Labor Code sets a minimal baseline, but the applicable collective agreement in your sector may provide more favorable conditions. Some company agreements add extra days for a sick child or maintain salary during a leave that is normally unpaid.
Where to find this information? The reference document is the collective agreement mentioned on your payslip. The HR department can also guide you. Checking this point before making your request avoids underestimating your rights or, conversely, requesting a leave that does not exist in your sector.
An employee informed of their collective agreement makes a more precise request, which will be processed more quickly by the employer. Approximation in the request lengthens response times and creates misunderstandings.
Recent trends show that fathers are increasingly taking family-related leave. In Belgium, data reported in May 2026 indicates a rise in parental leave taken by fathers, with several hundred additional requests compared to the previous year, and a slight decrease among mothers. This evolution makes requests for family absence more socially accepted, regardless of which parent makes them.
Anticipating a family absence remains inherently difficult. Knowing the available provisions, preparing standard justifications, and knowing whom to contact in case of emergency transforms a stressful situation into a managed process. The most useful reflex remains to review one’s collective agreement before needing it.
