A strike has begun today affecting regional transport throughout the Netherlands, causing expected delays and cancellations of services. The full extent of the disruption remains unclear and will depend on staff participation. The strike follows failed collective labour agreement negotiations between unions and transport companies including Arriva, Keolis, Qbuzz, Transdev, and EBS. While city transport in Amsterdam (GVB) and Den Haag (HTM) remains unaffected, Rotterdam experiences bus cancellations but normal tram and metro service. Utrecht anticipates reduced bus and tram frequency, and transport operators are struggling to provide accurate real-time information on service availability. Arriva continues to operate in regions like the Achterhoek, and trains run as scheduled in Groningen and Friesland, while unions CNV and FNV threaten weekly strikes if employers do not concede to demands for a 9.5% salary increase over two years and improved working conditions.
