A group of Greenwich workers will walk out on strike for 24 hours next Wednesday (May 21), complaining of a "bullying culture" at the council.
The occupational therapists, members of the Unite union, voted unanimously to strike over allegations - denied by Greenwich Council - of bullying, harassment and the suspension of a work colleague accused of being too friendly with staff.
Unite regional officer Onay Kasab said: "I am extremely proud of the Unite members who have voted to stand up against a bullying culture.
"We have given the employer every opportunity to deal with the bullying ﾖ but it has failed to tackle this issue.
"Even worse, it has victimised the whistleblowers, leading to the suspension on ludicrous charges of one of our members."
A spokesman said Greenwich Council refuted the allegations.
They said: "This isolated case involves differences between workplace colleagues in one team. No whistleblowers have been suspended.
"The council has carried out an investigation into the issues raised, and a report is being prepared. It would be inappropriate to comment any further pending the outcome."
They added: "We look forward to meeting with Unite this week in order to find a resolution."
