RMT Tube Drivers Set June 2 and 4 Strikes on London Underground

London travelers are being urged to prepare for major disruption on the Underground after RMT Tube drivers announced two fresh 24 hour strikes on Tuesday 2 June and Thursday 4 June 2026, in an escalating dispute over a proposed compressed four day working week.

New June Strike Dates After Earlier Walkouts Suspended

The June action follows a turbulent spring for London’s transport network, marked by intermittent strikes and last minute cancellations. Published coverage indicates that earlier RMT walkouts planned for May, as well as strikes pencilled in for 16 and 18 June, were suspended after progress in talks. However, the union has kept pressure on by moving industrial action forward to 2 and 4 June, warning that the core issues in the dispute remain unresolved.

Information compiled from strike tracking services and transport advisories shows that the RMT plans two separate 24 hour stoppages by Underground drivers. The first walkout is scheduled to begin just after midnight in the early hours of Tuesday 2 June and run until 23:59 the same day, with knock on disruption expected into the morning of Wednesday 3 June. The second is set to follow the same pattern on Thursday 4 June, with services likely to be heavily affected into Friday 5 June.

Some monitoring sites describe these June dates as “possible” or “contingent” on whether agreement can be reached in the weeks ahead, but public facing calendars and media reports currently list them as active strike days and advise passengers to plan for significant disruption.

Compressed Four Day Week at Heart of Dispute

At the centre of the conflict is Transport for London’s plan to introduce a voluntary compressed four day working week for Tube drivers. Publicly available commentary from union statements and analysis pieces explains that the proposal would condense existing driving hours into longer shifts across four days, while maintaining overall pay and headcount.

RMT representatives argue that the rosters tied to the four day model risk increasing fatigue, particularly on lines with early starts, late finishes and intense peak period loading. They have also raised concerns about the impact of longer individual shifts on safety margins in the event of incidents or operational disruptions. Union messaging highlighted in recent coverage stresses that members rejected earlier versions of the new roster arrangements in internal ballots.

Transport for London’s position, as summarised in multiple transport briefings, is that the compressed week is designed to be optional for existing drivers and would provide greater flexibility and additional rest days for those who choose it. Supporters of the change point to the potential for improved work life balance and more efficient staffing patterns, while critics insist that the fine detail of shift lengths and night work remains problematic.

Expected Impact on London Underground Services

Travel advisories for the capital indicate that the June strikes are expected to affect most, and potentially all, London Underground lines, depending on the final level of participation by RMT drivers. Past bouts of action in April and earlier in 2025 resulted in full or near full shutdowns on several lines, with others running sparse services limited to core sections of route.

Preliminary guidance from transport information services suggests that the Elizabeth line, London Overground, DLR and Tram services are not directly involved in the RMT dispute and are expected to operate, although these modes may be busier than usual as passengers seek alternatives. Buses, national rail services that intersect with the Underground, and cycling routes are all forecast to see increased demand on 2 and 4 June.

Journey planners recommend that commuters allow significantly more time to travel, especially at the start of service on Wednesday 3 June and Friday 5 June, when trains and staff need to be repositioned after the 24 hour walkouts. Even where limited Tube services are able to run, passengers are being warned to expect long queues outside stations, crowding on platforms and intermittent station closures to manage congestion.

Advice for Commuters, Visitors and Businesses

With the strike dates falling on a Tuesday and Thursday, the disruption is likely to split the working week and impact both office workers and visitors arriving for early summer events in the capital. Tourism and entertainment guides have already begun publishing alternative travel plans, advising people to check their route on the morning of travel and to consider walking or cycling for shorter inner city journeys.

Remote and flexible working patterns may reduce some of the pressure compared with pre pandemic strike periods, but business groups cited in recent reports still anticipate lost productivity and additional costs as staff contend with longer commutes or rearranged shifts. Large venues and hospitality operators are being encouraged to share clear travel information with guests and employees in the days leading up to the strikes.

Air travellers connecting through Heathrow, Gatwick, Stansted and London City airports are also being told to factor in extra time between central London and terminals, as Underground connections such as the Piccadilly line could be severely disrupted or closed on strike days. Rail and coach links, where available, are expected to be preferable for airport transfers during the affected period.

Uncertain Outlook Beyond Early June

The June 2 and June 4 walkouts are the latest stages in a dispute that has evolved over several months and shows no clear sign of a permanent resolution. Coverage of earlier negotiations indicates that limited progress has been made on some roster details, but a final compromise over the four day week has remained elusive.

Strike calendars and transport news outlets note that, beyond the early June dates, no further concrete strike days have yet been fixed. However, union communications repeatedly describe the dispute as ongoing and warn that additional action is possible later in the year if members’ concerns about rosters, fatigue management and job security are not addressed.

For now, the immediate focus for Londoners is preparing for the 2 and 4 June stoppages. As with previous Underground strikes, the scale of disruption will depend on last minute developments and the extent of driver participation, but current public information suggests that anyone relying on the Tube on those dates should plan for a difficult journey and consider backup options well in advance.
