The union said the walkouts by staff at Rail for London (Infrastructure) Limited were “highly likely to bring the Elizabeth line to a halt in the first strike of its kind since the line was opened in May 2022”.
The dispute centre around pay and proposed changes to pensions, with members voting nine to one in favour of strike action, which will take place on Thursday 12 January 2023.
Action short of a strike (effectively comprising a ‘work-to-rule’ instruction to only work contracted hours, take breaks and not provide contingency cover) will run from 12 January to 28 February 2023.
