A tube strike has been announced for Monday 6 June — the day after the four-day Platinum Jubilee weekend.
4,000 London Underground station staff members belonging to the RMT Union will walk out on the day, in response to TfL's plans to cut up to 600 jobs.
So far, we don't know exactly which tubes lines this will affect, or what the knock-on effect will be, although the BBC reports most zone 1 stations will likely close, with Overground services expected to remain open.
The large-scale strikes which took place in March 2022 was network-wide, with 10,000 staff members striking, so there's hope that with fewer than half that number on strike this time, disruption will be significantly less.
Meanwhile, night tube strikes are ongoing on the Central and Victoria lines on Friday and Saturday nights. The lines have remained open throughout, with trains running less frequently than usual.
Why's it happening? The RMT's General Secretary Mick Lynch says: "TfL is trying to bulldoze through 600 job losses on London Underground and our members are not prepared to accept that."
TfL has a different point of view, with Andy Lord, its Chief Operating Officer, saying: "It is particularly surprising that the RMT has threatened to spoil this moment when the nation is coming together as nobody has or will lose their jobs as a result of the proposals we have set out and there have been no proposals on pension changes."
We'll update this page when we know more about which tube lines the 6 June strike is likely to affect. In the mean time... maybe book the Monday off, and make it a five-day weekend?
