Employers Take Note! Limitation on Compensation for Transition Payment
On February 19, 2025, a bill was proposed that limits the compensation scheme for the transition payment in case of dismissal due to long-term disability to small employers. This proposal has significant implications for employers. The compensation scheme, originally intended to relieve employers, will now only be available to small employers. This article discusses the details and implications of this change. Limitation on Compensation for Transition Payment The compensation scheme for the transition payment was introduced to support employers in paying the transition payment after 104 weeks of illness. For many employers, it felt unjust to have to pay a transition payment after two years of continued salary payment. This often led to ‘dormant employment contracts’, where the employment contract was not terminated to avoid payment of the transition payment. With the new bill, the government aims to limit the compensation scheme to small employers. Small employers are defined as those who have been active for less than two years or have a wage bill of no more than 25 times the average taxable wage per employee. In 2025, this threshold was set at a wage bill of no more than € 990,000 per year. Implications for larger employers For medium-sized and large employers, this change means that they will have to pay the transition payment themselves in case of dismissal due to long-term disability. This can have significant financial consequences. The question arises whether employers are still obliged to terminate the employment contract if they are not compensated. The legislator leaves this to the judiciary, but it is likely that existing case law will be maintained. The change is expected to take effect on July 1, 2026. No transitional law is proposed, meaning the new rules will apply immediately. Employers will only be eligible for compensation if the 104-week waiting period ends before the law comes into effect. No specific arrangements have been made for special employers, such as social development companies.

Supreme Court and Self-Employed Workers: New Insights into External Entrepreneurship in Uber Ruling
On February 21, 2025, the Supreme Court ruled on the classification of employment relationships, specifically in the context of self-employed workers. As early as 2021, the Amsterdam District Court ruled that Uber drivers are employed under an employment contract, meaning that Uber must comply with the Taxi Transport Collective Labour Agreement (CAO). On appeal, the Amsterdam Court of Appeal asked preliminary questions to the Supreme Court regarding the role of the criteria ‘entrepreneurship’ in assessing the employment relationship. The Supreme Court has now provided answers to these questions. No hierarchy in criteria In the Deliveroo ruling, the Supreme Court ruled that the assessment of whether an agreement constitutes an employment contract depends on all the circumstances of the case. This includes the nature and duration of the work and the way the work and working hours are determined. In the Uber ruling, the Supreme Court clarified that there is no fixed hierarchy among these criteria. This means that all nine criteria must be equally weighed. For employers, this means that the classification of an employment relationship can be more complex, as every aspect of the working relationship must be assessed. This can lead to different outcomes, even if two workers perform the same work under the same conditions. Entrepreneurship: external aspects matter An important aspect emphasised by the Supreme Court is the entrepreneurship of the self-employed worker. The Supreme Court considers that the entrepreneurship criterium is not given more weight than the other criteria. This means that entrepreneurship can be decisive for the classification of the agreement. Not only does the general entrepreneurial situation of the worker in the relationship between the workers and the client play a role (internal entrepreneurship), but circumstances outside the relationship are also important (external entrepreneurship). In terms of external entrepreneurship, one might consider whether the worker is registered with the Chamber of Commerce, the number of clients the worker has outside the specific relationship, or the number of investments the worker makes for its own business. Retaining self-employed workers? Stimulate entrepreneurship! Employers are advised to encourage the external entrepreneurship of their self-employed workers. This can be done, for example, by encouraging them to take on assignments from multiple clients and ensuring that the worker clearly profiles themselves as an entrepreneur, for instance, with their own website.

Disclosure obligation of applicants with chronic physical complaints
When should an employee disclose information about chronic physical or psychological complaints during a job application? This was the subject of a recent ruling by the Court of Appeal in ‘s-Hertogenbosch. The disclosure of medical Information in the application procedure An applicant is not required to voluntarily provide medical information. This is only different if the applicant knows at the time of concluding the employment contract that their health condition would significantly and long-term hinder them in performing the job duties. Additionally, an employer may not ask questions about the health condition of a prospective employee, past sick leave, or any limitations during the application process, except in the context of a legally permitted medical examination. Ruling: the facts in the case before the Court of Appeal in ’s-Hertogenbosch The employee in this procedure had suffered from chronic psychological complaints (PTSD and an anxiety disorder) since 2011 following an unsuccessful surgery. The employee applied for a position as a security guard at a courthouse in October 2023 and did not disclose his medical situation during the application process, nor the fact that he was currently unfit for work as a security guard at the Department of Transport and Support (DV&O) of the Ministry of Justice and Security. The employee was hired and was declared fully recovered by the DV&O company doctor at that time. Shortly after starting at the courthouse, the employee fell ill. The employer requested the termination of the employment contract due to gross misconduct, arguing that the employee had failed to disclose his medical situation. The employer’s requests were denied in the first instance. Court’s judgment: no disclosure obligation for employee The Court of Appeal, like the subdistrict court, ruled that there were no grounds to terminate the employment contract. The court ruled that the disclosure obligation only exists if the illness or disability makes the applicant unfit for the position and the applicant knew or should have understood this. In this case, the employee had fallen ill several times at his previous employer, but this was not due to the specific job requirements, and the employee had always fully recovered. The position at the courthouse was less demanding than the position at DV&O, leading the employee to believe that his chronic illness would not be an issue. The employer argued that an applicant must also disclose their illness if the illness does not absolutely prevent the performance of essential job requirements, but the applicant will experience significant hindrances in fulfilling the role. The court dismissed this argument, as it would mean that every chronically ill person would have to disclose their chronic illness during a job application, which is contrary to the protection provided by the Dutch Equal Treatment Act on Grounds of Disability or Chronic Illness (Wgbh/cz). Practical tips As an employer, do not ask questions about the health condition, past sick leave, or any limitations of the applicant during the application process, unless it concerns a legally permitted medical examination. Additionally, ensure that the job requirements are detailed and are clearly stated in the job application and/or job profile. Discuss these requirements during the application process and ensure written documentation. If possible ask the former employer for references.

Alcohol and drug testing in the workplace: is it safe?
Under the Dutch Working Conditions Act, employers are obliged to provide a safe working environment. In this context, employers sometimes implement a strict alcohol and drugs policy. But how far can that go? Can an employer test an employee for alcohol or drug use? The Limburg District Court recently ruled on this issue. What can employers do in this regard? Ruling Limburg District Court – 20 February 2025 The case concerned SIF Netherlands B.V., a manufacturer of foundations for offshore wind farms, which had introduced a zero-tolerance policy regarding alcohol and drug use. One of its employees, employed since 2008 and responsible for quality inspections, tested positive for cannabis during an unannounced saliva test on 25 September 2024. Several colleagues also reported red eyes and strange behaviour. While the employee admitted to having used cannabis the previous evening, he denied being under the influence while at work. Nevertheless, SIF sought permission to terminate the employment contract on the basis of serious culpable conduct (ground e), a disrupted employment relationship (ground g), or a combination of grounds (ground i). The court rejected the request for termination. Although the question of drug use was considered legitimate, the court ruled that the test did not establish that the employee had been under the influence during work hours. Moreover, the test had been conducted unlawfully, breaching the employee’s right to a private life and privacy. As a result, the test results were excluded. Moreover, the witness statements from colleagues were deemed insufficiently substantiated to justify termination. The Legal Landscape Employers have a legal duty to ensure a safe working environment. The question is under which circumstances they may take a specific measure to test for drugs and/or alcohol. There is ample case law involving employees appearing at work under the influence of drugs or alcohol, where disciplinary actions were upheld. Yet, this employer’s request for termination was not upheld. Why is that? Employment Law Consequences If an employer suspects an employee of being under the influence in a way deemed unacceptable, disciplinary measures may be taken. Although Dutch law does not list exhaustive employment-related sanctions, potential measures include a formal warning, suspension, wage withholding, a fine, or even dismissal (including summary dismissal). The challenge of evidence Any sanction must be justified and proportionate to the alleged misconduct. The employer bears the burden of proving both the conduct and the proportionality of the measure. Courts also assess whether the evidence was lawfully obtained. Unlawfully obtained evidence may be excluded. In the context of alcohol or drug testing, courts will weigh the interest in truth-finding against the employee’s right to a private life and privacy. The Right to private life The right to a private life, protected under Article 8 of the European Convention on Human Rights (ECHR), shields employees from unwarranted intrusions. Alcohol and drug testing constitutes an infringement of this right. Such an infringement is only permitted under strict conditions. The court will assess whether the infringement serves a legitimate goal and is suitable to achieve that goal (necessity criteria), whether the infringement is proportionate (proportionality criteria) and whether there is a less intrusive alternative (subsidiarity criteria). GDPR considerations When an employer processes personal data of a employee, the General Data Protection Regulation (GDPR) applies. The results of alcohol and/or drug testing constitute a special category of data. Processing of such data is in principle prohibited, unless one of the exceptions under the GDPR applies. According to the Dutch Data Protection Authority (AutoriteitvPersoonsgegevens or ‘AP’), processing such data requires a specific legal basis. Currently, such a basis exists only for certain sectors (e.g. aviation and maritime and public transport). Practical recommendations for employers Testing for alcohol or drugs in the workplace is legally complex. Employers should verify whether their sector has a statutory basis allowing testing. Its advisable to consider adopting a written zero-tolerance policy outlining potential disciplinary measures in the case of a breach, including (immediate) dismissal. If you suspect an employee is under the influence during working hours, take them aside privately with a witness present. Ask the employee directly whether alcohol or drug use is involved and stress that this is a safety matter. If you are reasonably convinced that substance use is at play, suspend the employee and send them home. Document the incident and the meeting as thoroughly as possible and confirm your findings to the employee in writing, inviting a response. The appropriate sanction will depend on the specific circumstances. Seek legal advice as soon as possible before initiating further steps.

Dismissal and compensation for performing ancillary activities during illness
Article 7:653a of the Civil Code dictates that an employer may not prohibit or restrict an employee from performing ancillary activities  unless there is an objective reason for doing so. How does this clause work in practice, specifically when an employee is sick?    The effect of the ancillary activities clause  Ancillary activities are activities that an employee performs outside of his work. In principle, ancillary activities are permitted. In practice, the clause often includes the condition that an employee may only perform ancillary activities with the prior consent of the employer.  The employer may only refuse such consent if he has an objective justification. Examples of such an objective justification included in the law are:  the health and safety of the employee;  the protection of confidentiality of company information;  the integrity of public services;  the avoidance of conflicts of interest; and  the violation of a legal requirement.   The employer does not have to include the objective reason in the employment contract but must provide it when invoking the agreed-upon clause.  Performing ancillary activities during illness  Suppose an employee is sick and the employer finds out that this employee is performing ancillary activities. How does a judge rule in such a situation? In a case before the District Court of The Hague, an employee of the municipality of Amsterdam reports in sick. This employee is receiving  benefits due to occupational disability of 80-100%.   In July 2022, this employee reports in sick for her reintegration work due to a corona infection. The employer submits a termination request to the Netherlands Employees Insurance Agency (UWV) due to  long-term disability, but it is rejected because recovery is considered possible within 26 weeks. In October 2023, the employer again applies for a dismissal permit, which is then rejected because it turns out that the employee has been performing similar work at the Municipality of Rotterdam. An integrity investigation follows which shows that the employee has been working 24 hours a week at the Municipality of Rotterdam , which she did not report as stated in the absence protocol and code of conduct of the Municipality of Amsterdam. The Subdistrict Court ruled that the employee had violated Section 8 of the Civil Servants Act, which constitutes a breach of contract. The employee should have reported her intention to enter the service of the Municipality of Rotterdam. The employee should also explicitly have  asked permission to do so, and should have reported this to the company doctor. What was reported by the company doctor cannot be interpreted in any other way than that there was (a degree of) intent on the part of the employee to mislead the company doctor and therefore also the municipality. The overpaid wages must be repaid by the employee (Section 7:629 (5) of the Dutch Civil Code). The employment contract is terminated, without awarding the transitional compensation.  Practical tips for employers  Although the inclusion an ancillary activities clause employee may be important, an employer can also take steps in the situation where no clause is agreed upon but the employee does perform ancillary activities  during illness. The employer has several options depending on the situation. The employer may have grounds to  dismiss the employee either by instant dismissal or through a termination  procedure in court. In the latter case, the employer can choose to terminate  the employment contract for breach of contract. The options are highly intertwined with the circumstances of the case; in some cases, the employer has to tolerate that the sick employee also performs work elsewhere.  Contact Would you like to know more about ancillary activities?

The employment law implications of downloading (sensitive) company information 
Most employment contracts include a confidentiality clause. Under such a clause, the employee is obliged to keep sensitive company information confidential. It may happen that an employee downloads confidential and sensitive data, for example on his private laptop or phone. This could have major consequences for the employee.  Case Law  In a recent case before the District Court of Gelderland, both a confidentiality clause and a penalty clause had been agreed upon in the employee’s employment contract. The employer had informed the employee that he was dissatisfied with the employee’s performance and intended to terminate the employment relationship. A few days after the employer presented the employee with a settlement agreement, the employer received a security alert from Microsoft due to suspicious activity on the employee’s account.   When questioning the employee regarding the suspicious activities, it appeared that the employee had downloaded company files on his private laptop. The employee feared being excluded from access to his work environment and therefore could not defend himself against the alleged underperformance at work. However, the employee had downloaded a significant amount of files including reports from the company physician and performance of other staff members subordinate to employee.  The judge ruled that downloading all of this company-sensitive information was culpable. The employee thereby seriously damaged the employer’s trust. However, the high bar of serious culpability was not met because, in the judge’s opinion, the employee did not act intentionally to harm the employer.   In a recent similar case before the Court of Appeal in The Hague, an employee had also downloaded confidential and sensitive company information for the purpose of his defense at the the Netherlands Employees Insurance Agency (UWV). In this case it was not established whether the employee had only downloaded information which he could use for the procedure or also other (confidential) documents. The immediate dismissal by the employer was upheld.  Practical tips for employers  As an employer, it is wise to check whether an employee has downloaded information in the context of a dismissal case. Because the verification should not violate the General data protection regulation (AVG), it is good to have a policy in place when certain information may be checked. Sending confidential information can constitute  a violation of the confidentiality clause. If the employment contract includes a penalty clause for this circumstance, the employer can impose a fine on the employee.  It is wise to design the confidentiality clause so that even sending company information to employees’ own accounts counts as a violation.  Can La Gro be of assistance?   Do you have a question about confidentiality and protecting company information?
