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.

This is a measured change in public data during the event window, compared with a baseline before it. It shows timing, not cause. We describe an event as causing a change only when an official source says so.

Timeline

  1. Lashers at International Lashing Services and Matrans Marine Services stop work at 15:15 for a planned 48 hours, halting container operations at APM Terminals Maasvlakte II, Hutchison Ports Delta II, ECT Delta and Rotterdam World Gateway. [s1] [s4] [s5]
  2. With no agreement reached, FNV Havens extends the strike for an open ended period. [s1] [s6]
  3. A court orders the strike suspended from 07:00 on 2025-10-13 until 07:00 on 2025-10-17, leaving the union free to resume if no settlement is reached. [s2]
  4. Lashers return to work under the court order. The port authority reports 33 vessels at anchor, 15 of them deep sea container ships, and expects the backlog to last until the end of October. [s2] [s7]
  5. FNV Havens and the two lashing employers reach an agreement in principle on pay and working conditions. [s3]
  6. Union members vote to end the action, with a written ratification vote to follow over three weeks. [s3] [s8]

Cause

FNV Havens called the strike over pay for lashing staff, seeking an increase of 7 percent, later lowered to 6.5 percent, on top of inflation compensation, after negotiations with the two lashing employers failed. Attributed by: FNV Havens. [s2] [s5]

Resolution

2025-10-13 (13 October 2025): Work resumed on 2025-10-13 under a court ordered suspension of the strike. An agreement in principle followed on 2025-10-16, and members voted on 2025-10-17 not to resume the action. [s2] [s3] [s7]
