Industrial action is set to last three weeks following a dispute over outsourcing claims and tracking of workers at the Council’s Construction Services arm.
The council workforce of joiners, plumbers, electricians, labourers and scaffolders is also planning further daily strikes until the end of June.
Unite industrial officer Bob Macgregor, said: “We need cast-iron guarantees that there are no proposals by Dundee City Council to outsource any services to private contractors.
“It is a blatant failure on the part of council management to acknowledge the genuine concerns of the workforce including what we believe is the inappropriate monitoring of council vehicles. Unite will fight for our members every step of the way.”
A spokesperson for Dundee City Council said: “We remain in dialogue with trade union representatives to reach a resolution on the issues raised, and continue to believe they can be resolved without the need for strike action.
“We are committed to investing in and modernising the Council’s Construction Services to provide the service the public expects.
“That includes dealing with the significant backlog of repairs that built up as a result of the Covid-19 restrictions, which is why we have brought in subcontractors on a temporary basis to supplement our 320-strong workforce.
“There are no plans to outsource these roles.
“The service will always work to ensure in-house tradespeople are given the right skills, resources and management support to do the job.
“Our fleet vehicle tracking policy is implemented across all council services and has been in place for a number of years to safeguard staff, manage our fleet as efficiently as possible and ensure best value for service delivery to the residents of Dundee.”
