The annual Civil Public and Services Union conference is into its second day in Galway.
The union representing lower-paid civil servants has told its members that decentralisation is on track in the civil service sector and will be a success.
General Secretary of the CPSU Blair Horan said he is confident the process will be successfully completed in five or six years.
He said civil servants are used to being transferred between different government departments and are allowed to apply to a transfer to their home location, unlike state agencies who do not have this flexibility.
He also called on the Government to publish a list of the departments and numbers of posts that are to remain in Dublin.
Yesterday, the CPSU warned the Government it will launch an equal pay campaign that could cost the State €100m each year and €300m in back pay.
The union said the first claim will centre on clerical workers who are paid €10,000 less a year than prison officers for doing the same work.
