A 24-hour strike by Rail, Maritime and Transport union (RMT) members is causing severe disruption on the London Underground today, Thursday 4 June. The walkout began at 0:01am and will continue until 11:59pm, following failed talks between the union and Transport for London (TfL) over proposed changes to working hours.
Talks on Monday did not resolve the dispute, which centres on a new four-day working week. RMT says its members oppose the changes due to concerns over fatigue, longer shifts, and reduced flexibility in a safety-critical role. The drivers' union Aslef has accepted the new arrangements.
TfL advises passengers to check before travelling, as there will be virtually no service before 6:30am or after 9pm. Significant disruption is expected throughout the day, though a reduced service will run on most lines. The Elizabeth line, DLR, London Overground, and trams are operating normally but are likely to be very busy.
Claire Mann, TfL's chief operating officer, said the four-day week is voluntary and offers an additional day off with no reduction in contractual hours. She added that TfL is continuing to talk to union representatives to find a way to avoid further disruption.
Further strikes scheduled for June 16 and 18 have been called off, but the union has announced new potential strike dates of June 2 and 4 if the dispute remains unresolved.
