A three-day rail strike disrupted train services across the UK last week, amid an ongoing dispute between the RMT, Network Rail and train operators.
London Undergroundworkers also walked out on Tuesday, June 21, shutting down the city’s tube system.
But following the week of travel chaos, how likely are we to see more strike action this summer?
Will there be another London Underground strike?
On June 24, London Underground workers renewed the strike mandate, meaning that they have the right to strike over the next few months.
More than 50 percent of staff members voted, and of these members, more than 90 percent voted yes.
RMT general secretary Mick Lynch said: "This is a fantastic result for our members and proves that the arguments RMT has been making is endorsed by tube workers.
"TfL and the Mayor of London need to seriously rethink their plans for hundreds of job cuts and trying to take hard-earned pensions from workers who serve the people of London on a daily basis.
"We are acutely aware of the funding cuts being foisted on TfL by the Westminster government. However, Mayor Sadiq Khan needs to mount a serious campaign for the people of London, to get the capital city the funding it deserves for its public transport.
"He should not be trying to sacrifice our members’ pensions and jobs to fit within budget restraints laid down by Boris Johnson."
When is the next tube strike?
The RMT says no London Underground strike dates have been set, but that this will be decided by their National Executive Committee in due course.
Will there be another train strike?
RMT’s Mick Lynch told BBC Breakfast that the talks would continue and he would consult members to see “if and when there needs to be a new phase of industrial action.”
He said: “But if we don’t get a settlement, it’s extremely likely there will be.”
Further rail strikes could be likely if the discussions between RMT and Network Rail do not progress.
Additionally, the Transport Salaried Staffs’ Association (TSSA) union is currently voting on possible industrial action.
If it goes ahead, it could disrupt services from Avanti West Coast, CrossCountry, c2c, East Midlands Railway, LNER, Northern, and West Midlands Trains.
