London Underground to be hit by strike action

The RMT union has called strike action that will affect the resumption of the Night Tube which is due to start in a couple of weeks time.
The dispute is over plans that TfL wants to merge the existing Night Tube category of staff with the main driver’s pool so that all drivers are available for shifts. Although the changes make it easier for night-tube limited staff to become full-time drivers, they also mean that existing tube drivers could, in the future, be asked to work the night tube
