Fresh strikes have been called by the biggest civil service union in its long-running dispute over jobs, pay and pensions.
Members of the Public and Commercial Service union (PCS) at the British Museum will take industrial action in February’s half-term school holiday..
More than 100 members of the museum’s visitor services and security teams will take seven days’ action from 13 February.
More than 60 PCS members will start five days of action at the Driver and Vehicle Licensing Agency (DVLA) in Wales on the same day.
The union said the strike between 13 and 17 February was likely to disrupt the printing of driving licences and affect other print jobs at His Majesty’s Revenue and Customs (HMRC) and Department for Work and Pensions (DWP).
In a separate dispute, PCS members working as legal advisers and court associates in more than 80 courts across England and Wales have called four days of strikes from 3 February.
The announcement comes before a strike by up to half a million workers next Wednesday, including 100,000 PCS members.
The PCS general secretary, Mark Serwotka, said: “We warned ministers that our action would spread if they ignored our demands, and we’re good to our word.
“In failing to come to the table with any new money, the government has failed its own workforce – the very people they praised for keeping the country running during the pandemic.
“If the government was serious about resolving the dispute, ministers could resolve it tomorrow. Instead, they’re shamefully hiding their heads in the sand, hoping we’ll go away. We won’t.
“Wednesday will see the largest action by our union in a decade, with 100,000 of our members all over England, Scotland and Wales telling the government they demand a pay rise now to help them through the cost-of-living crisis and beyond.”
