A foreign-owned business operating in Belgium terminated a senior employee after a restructuring exercise. Within weeks, a formal claim landed with the tribunal du travail (Labour Court of Belgium). The employer had followed its own internal procedures – but Belgian employment legislation sets strict requirements that differ significantly from other European systems. The gap between internal policy and local legal obligation created immediate exposure.
Belgian employment law governs termination through a combination of individual employment contract terms and binding collective agreement obligations. An employer who fails to comply with the correct dismissal notice period or termination procedure faces a damages claim that may substantially exceed the original severance calculation. The resolution path runs through conciliation, and if unresolved, through formal Labour Court proceedings that typically conclude within three to nine months.
This case study outlines the strategic approach taken, the key milestones encountered, and three transferable lessons for international businesses managing employment disputes in Belgium.
Client profile and the challenge
The client was a mid-sized technology company headquartered outside the EU. It employed around forty staff in Belgium under a mix of individual employment contracts and sector-level collective agreements. Following a strategic restructuring, one senior manager was dismissed.
The dismissed employee had ten years of continuous service. Under Belgian employment legislation, long-tenured employees are entitled to extended dismissal notice periods – or a payment in lieu. The company had calculated notice based on its internal global HR template, which did not account for the specific notice period formula applicable in Belgium.
The employee also argued that the termination procedure had not followed the applicable collective agreement, which imposed additional consultation steps for managerial roles within that sector. A claim was filed with the Labour Court alleging both wrongful dismissal and a failure to observe the correct notice period. Social security contribution questions arose in parallel, as the payment structure of the severance package triggered a reporting obligation that had not been addressed.
The client engaged Ferraz & Whitmore at the point when the claim had already been filed. Time to the first hearing was approximately six weeks. For a full overview of the Belgian employment law service context, see our dedicated page on employment law in Belgium.
Legal strategy: rationale and sequence
The first step was a rapid audit of the employment contract, the applicable collective agreement, and the termination letter. This audit identified two clear deficiencies: the notice period applied was shorter than the statutory minimum, and the procedural steps required by the sector-level collective agreement had not been observed.
Rather than contest the claim on its merits at the first hearing, the team pursued a structured conciliation approach. Belgian Labour Courts conduct a mandatory conciliation phase before proceeding to a substantive hearing. This phase typically lasts one to three sessions and is conducted before a panel that includes lay judges from employer and employee representative bodies.
The strategy combined two elements. First, the team prepared a realistic damages assessment based on the correct notice period formula under Belgian employment legislation. This reframing of the financial exposure gave the client a clear view of the likely range of outcomes at trial. Second, the team identified that the social security reporting issue could be resolved administratively, separate from the court proceedings. Addressing that issue early reduced the overall risk profile and removed a potential aggravating factor from the dispute.
The conciliation approach was preferred over full litigation for a specific reason. Belgian Labour Court proceedings at the full merits stage can take nine to eighteen months. The damages exposure was significant but bounded. Early resolution through conciliation would preserve the client's operational relationships in Belgium and avoid the management time cost of extended litigation.

Key milestones and complications
The first complication arose during the document review phase. The applicable collective agreement had been revised two years prior to the dismissal. The revised version contained a modified notice period formula for senior roles. The original employment contract had not been updated to reflect this change. This created an ambiguity about which formula controlled.
Belgian courts apply the principle that the most favourable provision governs when a collective agreement and an individual employment contract are in conflict. The revised collective agreement formula produced a longer required notice period. The team had to rebuild the damages calculation on this basis before the first conciliation session.
The second complication was the social security question. The severance payment had been structured partly as a lump sum and partly as a continuation of salary-equivalent benefits. Belgian social security legislation treats these differently for contribution purposes. The reporting obligation had a short corrective window. Acting within that window avoided a penalty surcharge that would otherwise have compounded the overall cost.
Conciliation proceeded over two sessions. The employee's representatives initially sought an amount significantly above the revised damages estimate. After the team presented a detailed calculation grounded in the correct notice period formula and the applicable collective agreement terms, the parties reached a settlement within the conciliation phase. The matter did not proceed to a full merits hearing. For practitioners managing comparable scenarios in adjacent jurisdictions, our case study on employment disputes in Portugal offers a useful comparative perspective.
Transferable lessons for cross-border employment matters
Lesson one: local employment contract terms must be checked against the current collective agreement, not just the version in force at the date of signing. Collective agreements in Belgium are revised periodically. An employment contract that was compliant at signing may fall short of the current standard years later. International employers who apply a static global HR template without periodic local review face this risk at every termination.
Lesson two: the social security dimension of a termination package is a separate compliance track that runs in parallel with the employment dispute. Missing the administrative window for corrective reporting converts a manageable compliance issue into an additional financial penalty. Both tracks must be identified and addressed simultaneously from the moment a dispute is anticipated.
Lesson three: early legal involvement. before the internal termination procedure is finalised. is the most effective risk control available to an international employer in Belgium. By the time a claim is filed. The procedural record is fixed. The termination letter, the notice calculation, and the steps taken under any applicable collective agreement cannot be changed. Errors in that record define the shape of the dispute. A pre-termination review by a lawyer with direct knowledge of Belgian employment law costs a fraction of the conciliation or litigation exposure it prevents.
