Retained firefighters are to take industrial action next month.
Their union, SIPTU has accused the Government of failing to address a worsening recruitment and retention crisis in the service.
On Monday, SIPTU will serve notice of industrial action to local authorities across the country.
The action will commence on 6 June and will see members engaging in a campaign of non-cooperation with work outside of responding to emergency calls.
This will involve refusing to engage in training exercises and will see members using only analogue rather than digital technology.
If there is no resolution to the dispute, rolling strikes will begin from 13 June which will see a series of one-day work stoppages at 50% of fire stations at any given time.
If there is still no resolution, an all-out strike will begin on 20 June.
SIPTU represents around 2,000 retained firefighters across 200 stations around the country.
While larger urban areas have full-time fire brigades, many parts of the country rely on retained firefighters.
"Our members are responsible and will do what is required to ensure public safety isn't compromised but equally the Government must recognise that they have let down firefighters by not tabling serious proposals which they acknowledge exist to address the crisis in the service," said SIPTU Sector Organiser, Brendan O'Brien.
"Our members do not want to be in the situation however they have been left with no choice but to take this action to try to bring a resolution to this dispute."
In January, SIPTU members in the retained fire service voted overwhelmingly in favour of industrial action.
The union said that many firefighters are unable to take their leave entitlements due to staff shortages and have seen their incomes drastically reduced due to reductions in call outs over the last number of years.
The Minister for Housing, Local Government and Heritage Darragh O'Brien, has published a report on the future of the retained fire service which contains a number of recommendations aimed at addressing problems in the service.
Talks aimed at resolving the dispute broke down earlier this month.
The Department of Housing, Local Government and Heritage said that work is underway to begin implementing the recommendations set out in the report.
"I understand that during the most recent facilitation discussions held with LGMA and SIPTU, substantial progress was made on the provision of a revised model of retained fire service delivery that would provide for both an effective service delivery, and a suitable work/life balance for retained firefighters, including structured time off and flexible work arrangements," Minister O'Brien said in a statement.
"While a positive conclusion to the process to the satisfaction of all parties has not yet been reached, I encourage all parties to continue to engage constructively on resolving the outstanding IR issues within the established forum."
