The RMT issued no London Underground strike notice before 7 August; its news feed for the window covers other operators only and TfL's strikes page lists no Tube action.
New strike dates resolve YES only on a formal RMT strike notice or press release naming London Underground dates, confirmed on rmt.org.uk or TfL's strike page. Announcement timing is what counts, not the strike dates themselves — a notice issued before 7 August for September strikes still resolves YES.
We looked at the five major RMT disputes on the Underground since 2015 and asked whether each came back with new strike dates after its first round or a pause. They fall into two groups. Some ended after one round or a late offer. Others kept producing new strike dates until a deal was reached. Two of the five, in 2022 and 2023, were rounds of the same dispute over pensions and jobs.
