Trade union Unite has warned it could launch industrial action unless Nottingham City Council removes its threat of large-scale redundancies.
The council has tabled proposals to make 500 workers redundant - one in ten of the entire council workforce.
Unite regional officer Paula Stephens said: ‘Residents need to understand that if these cuts are implemented the council will no longer be able to offer many vital services.
‘The council must immediately remove this threat of redundancies and instead enter into meaningful talks with unions.
‘If the council fails to do so then we have no other course but to consider all avenues including industrial action.’
The council has been approached for comment.
