A STRIKE over a pay dispute has forced the closure of one of Scotland's major museums.

Members of the Public and Commercial Services Union (PCS) formed a picket line at the National Museum of Scotland in Edinburgh yesterday.

The union said staff appointed after January 2011 were denied extra pay for weekend working. PCS spokesman Robert Burns said: "Management may think this is a way to run a national institution but we don't."

A museum spokesman said the attraction would be open today.
