Firefighters across the UK have delivered a mandate for strike action - with 88% voting 'yes' on a 73% turnout.
In Northern Ireland, 94% of members voted in favour of action, during the strike ballot which opened on December 5 and closed on January 30.
The Fire Brigades Union says "in the hope of averting strike action", it has given the government and employers ten days to come forward with "an improved offer which could be put to a vote of members".
