New London Underground strike over four-day work week

Published on May 20, 2026 | Translated from Spanish

The London Underground faces a new strike following the failure of negotiations between the RMT union and Transport for London. Drivers are protesting against the voluntary introduction of a four-day working week with concentrated hours. TfL describes the strike as disappointing and reminds employees that they can opt for the five-day schedule. The walkout will affect the Circle, Piccadilly, Metropolitan, and Central lines from Tuesday at 12:00 BST.

The technical dilemma of concentrating hours into four days 🚇

From an operational perspective, TfL's proposal aims to optimize shift management by reducing one service day per driver. However, concentrating hours into a longer working day involves adjusting safety and fatigue protocols. Signaling systems and rest times between trips require recalibration to avoid incidents. The RMT argues that this reorganization has not been negotiated with the necessary technical depth, leaving gaps in contingency planning and workload distribution.

Four days of work, five days of complaints 😅

TfL's proposal sounds tempting: work four days and rest three. But RMT drivers are not convinced. Perhaps they fear that, in the end, the four-day working week will mean working eight days in four, or that the day off will be spent queuing at the human resources office. Meanwhile, passengers on the affected lines wonder if the solution to the conflict will involve a fifth day of strikes to decide on the fourth.
