There's no firm launch date for the Elizabeth Line (aka Crossrail), but as the Crossrail sections of the interchange stations begin to open, LU is altering staffing levels at stations like Bond Street, Tottenham Court Road, Farringdon, and Liverpool Street.
In most locations, whilst not perfect, the post-Crossrail rosters are roughly similar to current rosters in terms of levels of weekend working and extreme shifts. This is in part because, in 2018, union pressure secured additional full-time positions which helped rebalance rosters. Draft rosters were produced based on the new numbers, but LU then reduced CSA1 positions in the roster it plans to introduce at Farringdon, meaning the new CSA1 roster will lead to a big increase in both weekend working and extreme earlies and lates.
Workers at the station are beginning to discuss a potential fightback. LU says they can't afford to increase the staffing level sufficiently to rebalance the roster. Let's see if they miraculously fund some extra dosh if protests and picket lines disrupt the Crossrail prestige.
