Humberside firefighters will strike again next week.
The 24-hour strike across England will take place from 9am on Tuesday, December 9.
The Fire Brigades Union (FBU) is taking industrial action in a continued dispute with government about pensions.
The union argues that, after almost three years of discussions, firefighters still face a stark choice of either being sacked or being handed a severely reduced pension if they fail fitness tests as a result of their age.
Matt Wrack, FBU general secretary, said: "Firefighters are asking the Government to immediately open genuine negotiations to resolve this dispute.
"We need to be clear. We are not going to give up or go away.
"Firefighters will fight for however long it takes to secure a fair pensions deal – this dispute will not end as long as the regulations remain unchanged."
