Aslef wants its members to be paid triple time and be given a day in lieu A strike by train drivers on London Underground is taking place in a dispute about working on Boxing Day.
The drivers’ union Aslef called for triple pay and a day off in lieu for working on the bank holiday.
London Underground, which has accused the union of ignoring a prior agreement, sought an injunction to prevent the strike but that was rejected by the High Court.
The walkout could hit shoppers heading to the traditional Boxing Day sales.
London Underground says it intends to run as many Tube services as possible, as well as 700 bus routes and some river services.
In 1996, Aslef signed an agreement that it would consider Boxing Day a normal working day in return for higher pay and longer holidays.
But the union said increased Tube services on bank holidays meant drivers now had to work more public holidays than was the case when the agreement was signed.
London Underground challenged the strike notification, saying it was illegal as it was not worded properly, but after a hearing lasting almost four hours, the court ruled against the company.
It comes after a series of Tube strikes by members of the RMT union in recent months over plans to cut jobs in stations.
