National Museum of Scotland closed after strike action
The National Museum of Scotland in Edinburgh is closed due to industrial action.
The Public and Commercial Services union called the strike at the visitor attraction on Friday.
The union said the move was an attempt to get management to reverse its decision to remove weekend working allowances for staff.
The museum initially hoped to keep the attraction open, but confirmed on Twitter and its website it was closed.
On the social media site, the museum said the closure took place "due to strike action beyond our control".
The museum, on Chambers Street, would normally open from 12:00 until 17:00 on Boxing Day.
The dispute has been running for a year.
Earlier this week, Lynn Henderson, PCS Scottish secretary, said: "We are extremely disappointed that talks have yet again broken down without agreement.
"Management had an opportunity to avoid these strikes but failed to offer a solution to a problem that they made by taking up to £3,000 a year from their lowest paid staff."
A National Museum of Scotland spokeswoman said: "It is regrettable that the PCS has chosen to take this action, impacting on planned Christmas holiday visits by children and their parents and the large number of UK and international tourists who visit our museum."
The National Museum of Scotland was also closed in April, and on Boxing Day last year, due to strike action.
