On the first anniversary of the Elizabeth Line workers are set to stage strike action over a long pay dispute. On 24 May members of the Transport Salaried Staffs Association will strike and will ban overtime from 27 May to 4 June.
The union said that compared to other parts of the Transport for London (TfL) network their members are paid tens of thousands less.
The union’s organising director, Mel Taylor, said: “We’ve been in talks with management for almost a year now, yet the majority of our members have been offered an uplift of just over 1% to make up for the huge pay differentials.
“Elizabeth Line staff work weekends, nights and even Christmas Day, operating the world’s only fully digital railway, but many earn less than two thirds of the salary paid to other TfL staff in similar roles.
“Our members don’t want to have to take strike action, but they’ve had enough.”
