Councils across England and Wales have lost almost 600,000 workers since 2012, research from GMB has found
In 2012, local authorities employed 1,894,700 people, but by 2024 that figure had dropped to 1,295,300, a decrease of 599,400 jobs or more than 30%.
Birmingham had the largest fall, losing nearly 27,000 workers, a drop of 60%.
Derbyshire saw a reduction of 18,405 staff or almost 50%, while Staffordshire lost just over 16,000, or 63%.
Other areas hit included Hertfordshire, Essex, Cumbria, Surrey, Kent, Bradford and Norfolk.
The figures come as GMB and other unions begin pay talks with the Local Government Association (LGA) for the 2025/26 pay claim.
Kevin Brandstatter, national officer at GMB, said: “These figures are clearly appalling and show the deep and lasting damage austerity has done to our country.
“Council workers look after our loved ones, help our children learn, clear away our rubbish and keep our green spaces clean.
“They are the absolute backbone of society and should have had this year’s pay lift already – instead, we are waiting for a response from the Local Government Association.”
Brandstatter added: “GMB members working in local government face huge pressures, with the cost-of-living rocketing. They deserve a decent pay rise.”
