Glasgow Life put out an urgent message to all staff just hours before the opening ceremony appealing for volunteers to come forward, with several cultural venues failing to recruit enough workers across Saturday and Sunday.

A message to members states: "The protest at the City Chambers at 12.30 will go ahead, not only in support of Glasgow Life members but also in defence of the right to protest.
"We urge as many as possible to attend in their own lunch breaks."
