In April 2025, London Underground train drivers who are members of the craft union Aslef voted in favour of the implementation of a four-day working week to be part of pay negotiations that were taking place at the time. 
Aslef, which represents approximately 80 percent of London Underground drivers, negotiated a settlement with management which reinstated the 30-minute paid meal relief (which had been taken away from all workers back in 1993). This reduced the working week for train drivers by one hour to 34 hours per week, and they then began the process of implementing a four-day working week for train drivers.
