What is the strike about?
Tens of thousands of council workers and civil servants will strike in disputes over pay today. Unison and Unite said they expected more than half a million workers to join the 48-hour walkout this morning in protest at a rejected 2.45% pay offer.
What will be affected?
The walkout by members of three unions will lead to the closure of schools, libraries, museums and civic offices across England, Wales and Northern Ireland, while refuse collections will be cancelled and a host of other services disrupted.
How far are they willing to negotiate?
Local government employers have reiterated that the 2.45% was the final offer, warning that a bigger rise would have to be funded through higher council taxes or cuts in services.
What form will the protests take?
A series of rallies will be held by council workers across England, Wales and Northern Ireland, including Norwich, Cambridge, Leicester, London, Newcastle, Belfast, Portsmouth, Brighton, Bristol, Cardiff, Swansea, Sheffield and York.
Is there another pay dispute happening at the same time?
Yes, in a separate pay row, members of the Public and Commercial Services union, including driving test examiners and coastguards will take industrial action in the next few days. Driving test examiners will strike today, while staff at the Valuation Office Agency will take industrial action today and Thursday. Home Office and Land Registry workers will strike for part of Friday, coastguards will launch a 48-hour stoppage on Friday while employees at the Identity and Passport Service will strike for 72 hours from July 23.
Is there a more specific breakdown of the council services which will be hit by the strike?
A number of schools in Poole, Dorset, will be fully or partially closed on one or both days of the industrial action, while refuse collections and access to planning offices will be affected. Staff at Poole council and Hampshire county council reached an agreement with Unison for key staff to turn up for work as normal in critical services such as social care and child protection.
