A MARCH to save local library services will take place in Caerphilly on Saturday, starting at Senghenydd Square at noon.
In May, councillors voted to close ten libraries at the end of August, despite residents voicing their opposition in a public consultation.
One leisure centre is due to close under the plans, while two others will reduce their opening hours.
Unison highlighted that the council ignored advice from the scrutiny committee, which urged delaying the closures while the council worked with community groups to protect services.
Unison Caerphilly branch secretary Lianne Dallimore said: “Libraries are hubs for communities, engaging children and helping to tackle social exclusion.
“They also offer adult education support, advice and cultural events, and are often the only public space available to small communities.
“But these vital services and buildings are disappearing. Librarians are devastated and worried about their future.
“Council staff and residents are marching to save Caerphilly’s libraries and keep the area’s sense of community alive.”
Cllr Sean Morgan, Leader of Council said, “To be clear, I disagree with UNISON’s characterisation of the council’s decision on library services.
“The claim that the council has ignored residents or the scrutiny committee is simply not accurate.
“We carried out a comprehensive public consultation, consulted the scrutiny committee and considered all feedback. A decision was made on how best to deliver the service to the largest audience while the council remains under severe financial pressure.
"Having fewer libraries, but increasing overall library use at a fewer number of sites, based on the success of our Library Hub model trial at Rhymney, prioritises our resources in a way that increases current usage and ensures future viability."
