Firefighters have issued a further eight days of strike action in a row with the government over pensions.
Unions say the current proposals are unworkable and mean firefighters will face dismissal because they cannot maintain the high physical fitness requirements for their role until they are 60.
The proposals also mean that if firefighters opt for early retirement, the reduction in their pension would be “unacceptably high”.
Matt Wrack, FBU general secretary, said: “It is absolutely ludicrous that a government can impose a scheme which means that firefighters will have to ride engines and rescue people from fires up to age 60.
“This is unsafe and unrealistic for both firefighters and the public.”
The strikes will run for eight days from Saturday August 9 until Saturday August 16 between noon and 2pm and 10.59pm and 11.59pm
