Key points
- Tube drivers who are members of the RMT union are set to strike in April, May and June 2026 over proposed changes to working hours linked to a “condensed” four‑day working week.
- The strikes are scheduled for six separate days: 21–24 April, 19–22 May, and 16–19 June, with each walkout running from 12:00 Tuesday to 11:59 Wednesday and from 12:00 Thursday to 11:59 Friday during those months.
- The action is part of an ongoing dispute between the RMT and London Underground management, after union members voted in favour of industrial action in February 2026.
- The RMT argues that the proposed compressed‑hours four‑day week would increase fatigue and impact safety, while Transport for London calls the strikes “completely unnecessary” and says it is only trialling a voluntary four‑day week on one line.
- Services on all London Underground lines, as well as the London Overground, Elizabeth line, DLR and some bus routes, are expected to be disrupted on the strike days, though the effect is anticipated to be less severe than the September 2025 strikes.
London (The Londoner News) April 18, 2026 – London commuters are bracing for a fresh wave of Tube strikes in April, May and June 2026 as members of the RMT union move to walk out over proposed changes to working patterns, including a condensed four‑day working week, according to multiple outlets covering the dispute.
The strikes are scheduled for six days spread across the three months: 21–22 and 23–24 April, 19–20 and 21–22 May, and 16–19 June, with each industrial action running from midday Tuesday to just before midnight Wednesday and then again from midday Thursday to just before midnight Friday on those dates. Transport for London has warned that all Tube lines will be affected, and many passengers should expect significant disruption, with some services running only a limited timetable while others may be suspended altogether.
What are the strike dates and times?
Several reports, including those from the BBC and culture‑focused outlets tracking transport, confirm that RMT‑affiliated Tube drivers will stage 24‑hour strikes on six days this spring. The exact dates, as set out by union and TfL sources, are:
- 21–22 April 2026 (12:00 Tuesday – 11:59 Wednesday)
- 23–24 April 2026 (12:00 Thursday – 11:59 Friday)
- 19–20 May 2026 (12:00 Tuesday – 11:59 Wednesday)
- 21–22 May 2026 (12:00 Thursday – 11:59 Friday)
- 16–19 June 2026 (12:00 Tuesday – 11:59 Wednesday and 12:00 Thursday – 11:59 Friday, effectively four 24‑hour blocks across the final June dates)
As reported by Caroline Lowbridge of the BBC, the RMT has stressed that the action is “completely unnecessary” from management’s point of view, but the union insists its members have already rejected the proposed new working‑week model at the ballot box.
Why are Tube drivers striking?
The core issue is a proposed move towards a “condensed” four‑day working week with longer daily shifts, which the RMT argues would increase fatigue and compromise safety for drivers and passengers alike.
As reported by the BBC, RMT general secretary Eddie Dempsey stated that
“London Underground is attempting to impose significant alterations to work patterns that our members have already rejected,”
highlighting that the union’s membership had voted in favour of industrial action in February 2026. In a separate social‑media post picked up by BBC London and other outlets, the union reiterates that its members are
“opposing plans for a four‑day working week with longer shifts, raising concerns about fatigue and safety.”
Transport for London, by contrast, has described the strikes as “completely unnecessary” and has noted that it is currently trialling a voluntary four‑day week only on one line, not rolling it out universally. A TfL‑linked explainer, summarised by local‑news promoters, adds that the disruption is expected to be “less severe” than the September 2025 walkouts, when multiple groups of TfL and DLR staff were on strike simultaneously across much of the week.
Which lines and services will be affected?
The strikes are expected to hit all London Underground lines, with varying degrees of disruption depending on the day and the number of staff taking part.
As reported by a BBC London article compiled by regional transport correspondents, the RMT‑affiliated walkouts will also impact the London Overground, Elizabeth line and DLR, with some bus services operating on reduced or altered timetables to cope with the surge in demand. A leisure‑travel guide summarising the industrial action notes that “all tube lines will be affected,” though services on the Underground in April 2026 are expected to be “less severely disrupted” than during the September 2025 strike wave.
Transport for London has advised passengers to check the official TfL website and app before travelling, as services may be cancelled, delayed or replaced by alternative routes, and to allow significantly more time for journeys on strike days.
How does this relate to earlier Tube disputes?
This round of strikes follows an earlier set of planned walkouts in March 2026, which were initially announced for 24–27 March but were later suspended after progress in talks between the RMT and London Underground management.
As reported by the BBC, the March strikes were called off once negotiations advanced, but the union subsequently added the April–June dates to maintain pressure over the proposed changes to working patterns. Commenting on the broader pattern, a BBC London post‑format explainer notes that the latest strikes are occurring “again so soon after September ,” when Tube drivers and other TfL staff staged a highly disruptive week‑long strike that affected all Underground lines and the DLR.
Historical coverage of the 2025 September action, summarised by a transport blog, details that the disruption then lasted from 5–11 September and impacted every Underground line and the DLR for most of the week, underlining why the current spring 2026 walkouts are being watched so closely by regular commuters and policymakers alike.
What are the possible alternatives for commuters?
With six days of industrial action across April, May and June, travellers are being urged to consider alternatives to the Tube wherever possible.
As reported by the BBC and by local‑news outlets that track London transport, TfL is encouraging passengers to use buses, Overground, Elizabeth line and DLR services where they remain operational, and to stagger travel times to avoid peak‑hour congestion. Some business‑focused travel blogs reiterating the strike dates also advise that those working in central London or around major stations “consider working from home or adjusting working hours” on strike days to minimise disruption.
In addition, a TfL‑linked social‑media post cited by BBC London notes that while the strikes are “completely unnecessary,” the congestion on unaffected routes will likely be high, and passengers should “expect longer journey times and crowded conditions” on buses and Overground services during the walkouts.
What are the key remaining questions for the public?
For Londoners planning travel over the next few months, the strike schedule raises several practical questions about how services will be rescheduled and whether the dispute can be resolved before the June dates.
As reported by the BBC, the RMT has not ruled out further talks with London Underground management, but has maintained that the proposed four‑day working‑week model would require union members to accept longer, more tiring shifts. A TfL‑aligned statement, relayed by BBC London and other local‑media summaries, insists that the current plan is “a voluntary trial on one line” and that the strikes are being called despite that limitation.
Passengers are advised to monitor updates from TfL and the RMT, as the union and management could still agree a settlement that would lead to further suspension or cancellation of walks‑out, as happened with the March 2026 dates. Until such a resolution, however, the April–June strike calendar remains in place, with the potential to significantly affect daily life for millions of London commuters.
