A pipe strike has been proposed for June 6, the day most commuters will return to work after the Jubilee bank holiday weekend.
The 24-hour walkout, called by union RMT, could shut down the capital, affecting 4,000 London Underground employees.
If that level of action takes place, the pipe network must be closed for safety reasons, RMT argued.
RMT general secretary Mick Lynch said: “TfL is trying to solve the 600 job problem at the London Underground and our members are not willing to accept that.
“Terminal staff played a vital role in serving the traveling public and were the heroes of the 7/7 terrorist attacks.
“Instead of looking to cut jobs, TfL and Mayor Sadiq Khan need to put more pressure on the government to secure increased funding for the network so we can have a modern staffing system of the century.” 21″.
If it continues, the strike will begin one minute after midnight on Monday, June 6 and last for 24 hours.
Andy Lord, CEO of TfL, said: “We are deeply disappointed that RMT has announced unnecessary strike action on 6 June and share the frustration of Londoners that it This, and action related to the strike, was designed to disrupt the holiday weekend. . What is particularly surprising is that the RMT has threatened to spoil this moment when the whole country is pulling together as no one has or will lose a job as a result of the proposals we have made and none of them. pension change.
“If RMT chooses to continue with this unnecessary action, we will do everything we can to minimize any disruption and ensure everyone can still get the most out of the capital throughout the weekend. St.
“The devastating impact of the pandemic on TfL’s finances has made a program of change urgently needed but this change is being made in a way that ensures no one loses their job so we called on RMT to work with us, rather than disrupt London operations. recovery and our customers who deserve better. We have been in regular talks with RMT and hope to find an urgent resolution to this dispute to ensure they can eliminate this unnecessary action. “
It is separate from smaller-scale industrial action because it will take place during the very weekend of the Holy Year; The RMT said its members will walk out of Euston and Green Park stations on Friday, June 3 to protest bullying and a “toxic work environment” perpetrated by a particular manager. .
The strikes will last all day on Friday and will affect passengers wanting to travel on the Victoria, Jubilee and Piccadilly Lines.
