Workplace Investigations

As a general rule, sick leave does not prevent an investigation from progressing. Depending on the nature of the sickness, the employee can attend hearings and take part in the procedure. If the sickness prevents the employee from participating, the employer can put the process on hold temporarily.

If the employee under investigation goes off sick during the investigation, they will generally be treated as a regular employee on sick leave, meaning they are entitled to continued salary payment and that both employer and employee have a reintegration obligation. This entails regular consults with the company doctor to determine how recovery progresses and when the employee can return to work. If the employer suspects that the employee is merely calling in sick to delay the investigation and such suspicion is not confirmed by the company doctor, the employer can ask the Employees Insurance Agency (UWV) to give a second opinion. When it is determined that the employee is in fact fit for work, the employer can oblige the employee to return to work and cooperate with the investigation. If the employee fails to comply, the employer can – after due warning – suspend the employee's salary payment.

The employee’s participation in the investigation is vital for a fair assessment and to ensure that the employee has been allowed to defend himself or herself against the allegations. As such, every reasonable effort must be made by the employer to adjust the investigation process so that the employee can take part in the investigation. For example, if the employee goes off sick and thus cannot attend the investigation interviews or disciplinary hearings, the investigation should be carried out as much as possible without resorting to the employee in question, by initially exhausting the other available options (such as conducting interviews or disciplinary hearings with other available witnesses). However, if the employee’s absence takes longer than is reasonably expected or the matter at hand must be dealt with urgently, the employer may consider concluding the investigation and determining the next steps based on the information at hand. In such a case, it is recommended to explain in the investigation report the reasons why the employee could not take part in the investigation process (ie, why an interview or disciplinary hearing, etc, could not have been arranged with the employee) along with supporting documentation evidencing the employer’s efforts to involve the employee in the investigation process and the employee’s excuse for not participating interviews or disciplinary hearings.
