The afspiegelingsbeginsel in Dutch redundancy law
When an employer dismisses employees for economic reasons (bedrijfseconomische redenen), the order in which employees are selected for redundancy must follow the statutory reflection principle (afspiegelingsbeginsel), regulated in Article 11 of the Dismissal Regulations (Ontslagregeling). The afspiegelingsbeginsel requires that the age composition of the remaining workforce within each job category (categorie uitwisselbare functies) proportionally mirrors the age composition before the redundancy.
For this purpose, employees within a job category are divided into five age bands: 15-24, 25-34, 35-44, 45-54, and 55 and over. Within each age band, the employee with the shortest service (ancienniteitsvolgorde) is selected for dismissal first - the so-called LIFO principle within the age band. The employer cannot deviate from this method without UWV permission or a basis in a collective labour agreement.
Interchangeable functions under Dutch redundancy law
The starting point is the identification of interchangeable functions (uitwisselbare functies): positions that are comparable in terms of content, required competencies, and employment conditions. Employees who hold interchangeable functions form a selection pool. A common employer error is defining job categories too narrowly or too broadly, which can result in an incorrect selection order. The UWV scrutinises the employer's categorisation carefully when assessing the dismissal application (ontslagaanvraag).
Exceptions and alternatives
Certain employees are exempt from the afspiegelingsbeginsel and cannot be selected for redundancy regardless of the principle: employees on sick leave (zieke werknemers) during the first two years of illness, employees with special dismissal protection (pregnant employees, works council members), and employees who are indispensable to the organisation (onmisbaarheidsvereiste) - though this exception is rarely granted by the UWV in practice.
The social plan (sociaal plan) agreed between the employer and trade unions or works council may contain alternative selection criteria, subject to UWV approval. The social plan may also provide for seniority-based selection or voluntary departure schemes (vrijwillige vertrekregeling) as alternatives to the standard afspiegelingsbeginsel.
Before applying the afspiegelingsbeginsel, the employer must first dismiss any employees on temporary contracts and employees who have exceeded the AOW pensionable age, and must exclude from the selection those protected by a dismissal prohibition. The employer may additionally deviate from the standard afspiegelingsbeginsel for at most 10 per cent of the workers to be dismissed, on the ground that specific employees are functioning above average or are expected to do so - but this exception is subject to strict requirements under Article 16 of the Dismissal Regulations and is rarely approved by the UWV in practice. The afspiegelingsbeginsel replaced the previous last-in-first-out (LIFO) rule in 2006 specifically because the LIFO approach had led to workforces dominated by senior workers and disadvantaged younger employees and new entrants, raising concerns about potential age discrimination.
