The ASLEF union has announced strike action on Friday the 1st of September and a ban on overtime working on top of the RMT union’s strike action on Saturday the 2nd.
Stuart Meek, Chief Operating Officer at South Western Railway, commented:
“We’re sorry that customers will once again face disruption due to strike action by the RMT union.
“Once again, I must ask our customers to only travel if absolutely necessary on Saturday. If you do have to travel, please check your entire journey as these strikes also affect other train operators.
“A large number of events take place on Saturday and while some trains will be running, we expect them to be very busy. If you’re travelling to one of those events, please check before you travel and consider alternative transport if possible.
“We’re thankful for our customers’ patience during these latest RMT strikes.”
