What happened
From 2025-10-08 (8 October 2025) lashing workers at the Port of Rotterdam went on strike, stopping container loading and discharge at the main deep sea terminals. About 700 lashers employed by International Lashing Services and Matrans Marine Services walked out at 15:15 local time in a pay dispute led by the union FNV Havens. A planned 48 hour action was extended without an end date on 2025-10-10. A Dutch court suspended the strike from the morning of 2025-10-13 (13 October 2025), when work resumed, and the port authority said the queue of waiting ships would take until the end of October to clear. Negotiators reached an agreement in principle on 2025-10-16 and members voted on 2025-10-17 to call off further action. A separate slowdown by Belgian pilots affected Antwerp at the same time and is not part of this event.
