Cork City Council community wardens will commence a campaign of industrial action tomorrow.
Their union SIPTU has accused the council of failing to engage in an evaluation of the roles the wardens carry out.
Community wardens work with local communities and report issues to the council such as abandoned cars, litter, dumping, repairs and anti-social behaviour.
"Despite the important work carried out by community wardens, and a recommendation of the Labour Court, the management of Cork City Council has refused to engage in an evaluation of the roles these workers carry out," said SIPTU organiser Con Casey.
"This is essential if we are to retain and develop these workers for this service in assisting communities across the city," Mr Casey said.
The wardens have voted for industrial action, up to and including strike action.
Tomorrow's action will consist of the workers placing a picket on Cork City Hall.
They will only carry out the work which they are strictly contracted to perform and will not take part in additional training.
SIPTU said the industrial action will escalate if Cork City Council fails to enter into a process where the functions of the workers are evaluated.
