Croydon Housing and Homelessness Department workers have voted to strike over the current restructure plans.
GMB members at the authority will walk out on 28 and 29 June after a 94 per cent majority voted to walk out.
Workers are worried and angry over a restructure across this vital department.
Croydon Council declared bankruptcy for the third time in November 2022.
Rachael Baylis, GMB Organiser, said:
“Croydon Council is totally ignoring our members who collectively have decades of experience working in this service.
“They're frontline workers and know what the service needs - yet senior managers that have been in post less than 18 months are trying to force through this absolute farce of a restructure.
"These current plans for the service raises severe concerns around safeguarding, provision and remaining legally compliant.
“Our members will be showing the full force of their anger at not only these plans but also the way they’ve been treated. They feel as though they're being set up to fail.
“Council housing workers often get the blame when things go wrong but should this current restructure continue, any failings land squarely at the door of Croydon Council.
“They have been warned."
