ASLEF - The Train Drivers' Union

High Impact Labour Party affiliated
Founded in 1880, ASLEF represents train drivers across passenger and freight operators, as well as parts of London Underground and some light rail systems. Because drivers are central to railway operations, ASLEF can have significant influence in pay, rosters and safety-related negotiations. Its bargaining agenda is typically focused on driver-specific terms and conditions, including pay, working time arrangements and operational safety.
