Firefighters across the country have suspended their ballot on industrial action.
It comes after representatives of SIPTU met with the Minister for Local Government Alan Kelly to discuss their concerns over the implementation of the 'Keeping Communities Safer' plan.
Members of the service say it will reduce the number of officers that are deployed on tenders to deal with fires.
The department insisted changing the crew number would simply keep Ireland in line with international norms.
The directive would see attending crews reduced by one firefighter.
SIPTU sector organiser, Brendan O'Brien, outlines the deal that has been reached.
Back in January, retained fire services were balloted for industrial action over the issue.
About two-thirds of firefighters in Ireland are known as retained firefighters - while they are trained firefighters they are not full-time, but paid a retaining fee and paid on a per-call basis.
Retained firefighters and stations are located primarily in smaller towns and rural locations - where the number of calls, risk factors and cost dictate against a full-time brigade.
