Anti-cuts campaigners celebrated a victory last week after they forced the mayor of Tower Hamlets in east London into a U-turn over cuts to the Children and Adult Mental Health social work team.
The council has also said it is reconsidering plans to close four nurseries.
Workers and activists demonstrated outside the town hall on Wednesday of last week and vowed to keep fighting attacks on services.
Campaigners also voiced anger at the Islamophobic attacks on mayor Lutfur Rahman.
Tower Hamlets Unison branch secretary John McLoughlin called for resistance to the attacks and called on the mayor to stand with trade unionists against the cuts.
