Staff members will strike tomorrow to fight the proposed closure of a Sheffield job centre.
Since the proposed closure of the Eastern Avenue job centre was announced in January, union members have mounted a campaign to stop it.
Local MPs have given support and a local petition has been signed by many claimants who use the Jobcentre.
The Public and Commercial Services Union has opposed the closure in negotiations with the Department of Work and Pensions but, to date, DWP has refused to withdraw its proposal to close Eastern Avenue Job Centre.
As part of the Conservatives' cuts, the DWP has announced proposals to close 78 job centres.
PCS general secretary Mark Serwotka said: “The Eastern Avenue job centre is located in one of the most deprived parts of Sheffield and provides a vital service to the local community.
"Closing the job centre would have a massive impact. Our message is clear, listen to staff and the local community, stop the cuts and defend public services.”
