A week-long series of strikes on the London Underground starting Sunday has been suspended by the unions involved after talks with Transport For London at Acas.
Members of Aslef and the RMT had both called off their separate actions, which had been predicted to cause severe disruption for commuters in the capital.
Aslef's Finn Brennan said: "After a week of intense negotiations, we have made real progress in making sure our members' working conditions and pensions are protected."
However, RMT general secretary Mick Lynch cautioned that the strikes had not been called off just suspended.
"RMT's strike mandate remains live until October and we are prepared to use it if necessary.
Lynch added though there were now “longer guarantees on protection of earnings, no pension changes for at least three years and so-called productivity proposals which would have damaged the terms and conditions of RMT members have been halted”.
Aslef said Tf had also withdrawn plans to impose an “attendance at work” procedure while proposed changes on trains modernisation had also been shelved.
TfL also said any reform of its pensions scheme would not take effect until September 30, 2026 and after the next election.
