Employment Law Update in Belgium: Q1 2026

Belgium employment law 2026 has entered a period of notable legislative activity, with several reforms taking effect or advancing through parliament in the first quarter. Employers operating in Belgium - whether domestic companies or foreign groups with Belgian subsidiaries - face updated obligations on working time, telework, pay transparency, and collective dismissal procedures. This guide summarises the most material developments, explains what has changed in practice, and identifies the compliance steps that HR and legal teams should prioritise.

The most structurally significant development of recent months is the transposition of the EU Pay Transparency Directive into Belgian law. The directive, which Belgium is required to implement progressively, introduces binding obligations on employers to disclose pay ranges in job postings, provide individual pay information on request, and report gender pay gap data to a competent authority. Belgian legislators have been working through the implementing legislation, and current drafts indicate that larger employers - those with more than 250 employees - will face the earliest reporting deadlines, while smaller employers will follow on a phased schedule.

Alongside pay transparency, the Belgian parliament has advanced amendments to the Act of 3 July 1978 on employment contracts. The recent amendments clarify the rules on trial periods, which Belgium had already largely abolished for blue-collar and white-collar workers, and introduce tighter requirements around the written confirmation of variable remuneration components. Employers who rely on bonus schemes, commission structures, or other variable pay must now ensure that the calculation methodology is documented in the employment contract or a separate written annex.

A further development concerns the Act of 26 March 1999 on the Belgian employment action plan, which has been updated to reflect new obligations around skills development and training. The current framework requires employers above a certain headcount threshold to allocate a minimum percentage of payroll to formal training. Recent regulatory guidance has clarified what qualifies as "formal training" for this purpose, excluding informal on-the-job coaching and requiring documented programmes with measurable outcomes.

Telework remains one of the most actively regulated areas of Belgian employment law. The framework established by collective bargaining agreement No. 149 (CBA 149), concluded within the National Labour Council, continues to govern structural telework arrangements. Recent guidance from the Federal Public Service Employment, Labour and Social Dialogue has clarified several ambiguities in CBA 149';s application, particularly around the right of employees to request telework and the employer';s obligation to respond in writing within a defined period.

Under the current framework, employers must provide a written, reasoned response to a telework request within a period of one month. A refusal must state specific operational or organisational grounds. In practice, many employers have been issuing generic refusals, which the Federal Public Service has indicated will not satisfy the written reasoning requirement. A common mistake is treating the telework request process as a formality rather than a substantive obligation with potential legal consequences if handled incorrectly.

The right to disconnect, introduced by CBA 149 and reinforced by subsequent guidance, also requires employers to have a documented policy on digital availability outside working hours. Employers who have not yet formalised this policy - or who have a policy that exists only on paper without practical implementation - face increasing scrutiny from labour inspectors. In practice, founders and HR managers of foreign-owned Belgian entities often underestimate this requirement, assuming that a group-wide policy drafted in another jurisdiction satisfies Belgian law. It does not: the policy must reflect Belgian-specific rules and be communicated to Belgian employees in a language they understand.

Flexible working time arrangements have also been updated. The Act of 5 March 2017 on workable and agile work introduced the annualised working time framework, and recent amendments have adjusted the maximum daily and weekly working time thresholds applicable under that framework. Employers using annualised hours must update their work regulations and, where applicable, their collective agreements at company level to reflect the revised thresholds.

The EU Pay Transparency Directive is the most consequential piece of employment legislation affecting Belgian employers in the near term. Belgium employment law 2026 will increasingly be shaped by how this directive is transposed and enforced. The directive requires employers to include salary ranges or minimum pay in job advertisements, prohibit pay secrecy clauses that prevent employees from discussing their own remuneration, and provide employees with information about average pay levels for comparable roles disaggregated by gender.

For Belgian employers, the practical implications are significant. Many existing employment contracts contain confidentiality clauses that cover remuneration. Under the incoming framework, such clauses will be unenforceable to the extent they prevent an employee from disclosing their own salary. Employers should audit existing contracts and template agreements now, rather than waiting for the implementing legislation to be fully enacted.

The gender pay gap reporting obligation will require employers to calculate and report the difference in average pay between male and female employees across defined job categories. The competent authority responsible for receiving and publishing these reports in Belgium is the Institute for the Equality of Women and Men, which already publishes sector-level data. The new framework will extend this to employer-level reporting for larger organisations.

A non-obvious requirement is that the pay transparency framework applies not only to base salary but to all components of remuneration, including bonuses, allowances, overtime pay, and benefits in kind. Employers who have structured variable pay in ways that are opaque or inconsistently applied across comparable roles will need to review and potentially restructure those arrangements before reporting obligations come into force.

Belgium';s collective dismissal framework, governed by the Act of 13 February 1998 (the Renault Act) and its implementing royal decrees, has seen procedural clarifications that affect how employers must conduct information and consultation with employee representatives. The Renault Act requires employers contemplating collective dismissal to notify both the competent regional employment authority and the works council or trade union delegation before any dismissal decisions are communicated to individual employees.

Recent case law from the Belgian labour courts has reinforced the principle that the information and consultation procedure must be genuine and not merely formal. In several recent decisions, courts have found that employers who provided information to employee representatives only after the decision to restructure had been finalised - rather than at a stage when the outcome could still be influenced - had violated the Renault Act. The consequence is that dismissals carried out in breach of the procedure can be declared null and void, with significant financial exposure for the employer.

A practical scenario illustrates the risk. A foreign group decides at headquarters level to close a Belgian production facility. The Belgian management team is instructed to implement the closure and begins the Renault Act procedure. However, because the decision was made at group level before the Belgian consultation process began, the procedure is treated by the courts as a formality. The result is a finding of procedural non-compliance, leading to reinstatement claims or enhanced severance obligations.

A second scenario involves a Belgian employer that reduces headcount through a series of individual dismissals timed to fall below the collective dismissal threshold. Belgian law and recent regulatory guidance have made clear that artificially staggered dismissals designed to circumvent the collective dismissal threshold will be scrutinised. The relevant thresholds under the Renault Act depend on company size, and the calculation period is 60 days. Employers should take legal advice before structuring any significant headcount reduction.

The competent regional employment authorities - the Flemish Public Employment Service (VDAB), Actiris in Brussels, and FOREM in Wallonia - each have specific notification requirements and timelines. Employers operating across multiple Belgian regions must notify the relevant authority for each region in which affected employees work.

Belgian social security law is administered by the National Social Security Office (ONSS/RSZ), and recent developments have focused on two areas: the classification of workers and the treatment of cross-border remote workers.

Worker classification remains a persistent compliance risk. Belgian law, reinforced by the Programme Act of 27 December 2006 and subsequent amendments, establishes criteria for distinguishing employees from independent contractors. The criteria cover the employer';s authority to give instructions, control over working time, integration into the organisational structure, and economic dependence. Recent enforcement activity by the social inspection services has targeted sectors with high rates of platform-based work and project-based contracting.

A common mistake made by foreign companies entering Belgium is to engage Belgian-based individuals as independent contractors under a foreign services agreement, without assessing whether the relationship meets the Belgian criteria for employment. If the relationship is reclassified, the employer becomes liable for unpaid social security contributions, interest, and penalties, potentially going back several years.

Cross-border telework has created a specific social security complication for employers with employees who live in one country and work remotely for a Belgian employer. The EU social security coordination rules, set out in Regulation 883/2004, determine which country';s social security system applies. Recent guidance from the ONSS/RSZ and the multilateral framework agreement on cross-border telework have provided a mechanism for employees who work a significant portion of their time in their country of residence to remain affiliated to the Belgian system, but this requires a formal application and agreement between the relevant national authorities.

Many employers have not yet formalised these arrangements, leaving both the employer and the employee in an uncertain position regarding social security coverage. The administrative process is manageable but requires proactive engagement with the ONSS/RSZ and, where applicable, the social security authority in the employee';s country of residence.

What are the most immediate compliance obligations for Belgian employers under the pay transparency rules?

The most immediate step is to audit existing employment contracts and template agreements for pay secrecy clauses that would prevent employees from discussing their own remuneration. Such clauses will become unenforceable once the implementing legislation is in force. Employers should also begin collecting and organising pay data by job category and gender, since the reporting obligation will require this data to be available at short notice. Larger employers face earlier deadlines, but all employers above the minimum threshold should treat preparation as an ongoing process rather than a last-minute exercise. Taking legal advice on the specific Belgian implementing rules, which may go beyond the minimum requirements of the EU directive, is advisable at this stage.

How long does the collective dismissal consultation process take in Belgium, and what are the cost implications?

The Renault Act procedure involves a mandatory information and consultation period that typically runs for a minimum of 30 days, though in practice the process often extends to 60 days or longer when employee representatives request additional information or when negotiations over a social plan are complex. The cost implications include not only the severance payments required under Belgian law - which are calculated based on the employee';s remuneration and length of service under the unified statute introduced by the Act of 26 December 2013 - but also the costs of a social plan, outplacement services, and potential litigation if the procedure is challenged. Foreign employers frequently underestimate the total cost of a Belgian collective dismissal, particularly the obligation to fund outplacement support and the potential for enhanced severance if procedural requirements are not met.

Can a Belgian employer refuse a telework request, and on what grounds?

Yes, an employer can refuse a telework request, but the refusal must be in writing and must state specific operational or organisational grounds within one month of the request. Generic refusals citing "business needs" without further explanation are unlikely to satisfy the requirement. Acceptable grounds typically relate to the nature of the role, the need for physical presence for operational reasons, or the inability to provide the necessary technical infrastructure. An employer who fails to respond within the one-month period, or who provides an inadequate written response, risks a finding that the refusal was improper, which can expose the employer to claims before the labour courts. Employers should ensure that their HR teams are trained on the procedural requirements and that refusal decisions are reviewed by legal counsel before being communicated.

Belgium';s employment law landscape is evolving on multiple fronts simultaneously, with pay transparency, telework regulation, collective dismissal procedure, and social security compliance all requiring active attention from employers. The common thread across these developments is a shift toward greater procedural rigour and documentation: Belgian law increasingly requires not just that employers do the right thing, but that they can demonstrate it in writing. Employers who treat compliance as a documentation exercise rather than a substantive obligation will find themselves exposed when inspectors or courts look beyond the paperwork.
