London Underground customer service managers are to stage a fresh strike in a dispute over terms and conditions.
Members of the Transport Salaried Staffs’ Association (TSSA) will walk out on Friday April 26 and then ban overtime until May 5.
The union said the action is likely to cause Tube stations to close at the last minute, including into Saturday morning.
The workers held a previous strike earlier this month.
TSSA general secretary Maryam Eslamdoust said: “It’s clear that our customer service managers’ strike on April 10 made a real impact, many stations shut at short notice, and we had overwhelming support from the public.
“Because of London Underground’s refusal to get back round the negotiating table, we have been forced to take further strike action this week.
“London Underground must now come clean with the public. Their refusal to negotiate seriously and fairly with our union will lead to stations closing at the last minute and other stations being understaffed.
“We have made it clear that our union will not accept the continued threats to our members’ roles, locations, terms and conditions to stand unchallenged.
“We will continue to take sustained action until London Underground is prepared to negotiate with us in good faith.”
Earlier this week Aslef announced that train drivers at 16 rail companies are striking from May 7 to May 9 amid a long-running dispute.
“The dispute is to get train drivers, who have not had an increase in salary for five years, since their last pay deals expired in 2019, the pay rise they deserve,” said Aslef as it announced the strike on Monday.
“The cost of living has increased significantly in the last five years.”
On Tuesday Unite union announced that nearly 800 workers at Heathrow Airport will go on strike between May 7 and May 13.
A Tube driver walkout planned by Aslef union members for May 4 was scrapped after a breakthrough in negotiations with Transport for London.
