Thousands of London Underground workers are to go on strike in a long-running dispute over jobs and conditions, the RMT union has announced.
Members of the Rail, Maritime and Transport union (RMT) will walk out on October 4 and 6.
More than 3,500 RMT members are involved in the dispute, and that the strike will shut down Tube services in the capital.
The union has been locked in a row over the plans to cut the jobs of 600 station staff, as well as working conditions.
Safety concerns have also been raised over higher workloads, more lone working and increased fatigue.
RMT general secretary Mick Lynch said: “Station staff have had enough of having their livelihoods threatened by job losses and attacks on their terms and conditions.
“They have a vital role to play assisting vulnerable passengers access the network safely and ensuring that the tube is a safe environment for passengers.
“These job cuts and attacks on conditions are going to lead to more unstaffed stations, temporary closures and rising passenger anger.”
He said the savings made by the cuts will be “negatable” and will lead to shortages that are “unacceptable”.
“We call on Mayor Sadiq Khan to meet us urgently to discuss this matter,” he added.
