South Yorkshire firefighters are set to walk out again next week amid their long-running pensions row with the government.
Members of the Fire Brigades Union will go on a 24-hour strike on Wednesday, February 25.
It will be the 66th time FBU members have been on strike since the dispute over pensions and retirement age broke out two years ago.
Matt Wrack, FBU general secretary, said: “Firefighters are unbelievably angry with the disgraceful actions of this government.”
A spokesman for the Department for Communities and Local Government said: “All fire and rescue authorities have robust and well-tested plans in place that include back up support if needed.
“Public safety is our priority.”
