Firefighters in Ilkeston and the rest of the country will take part in a further eight days of strike action from tomorrow (Saturday).
Local members of the Fire Brigades Union (FBU) will join the action, which is in response to a long-running dispute over pension proposals.
The union claims firefighters could face dismissal if they cannot maintain the high physical fitness requirements necessary for their role until they are aged 60.
Matt Wrack, general secretary of the FBU, 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.
“We know it, and the public know it, but the government will not listen to the evidence based case we have made to them”.
During times of industrial action, Derbyshire Fire and Rescue Service will continue to provide an emergency response service, albeit at a reduced level.
The service is calling upon residents in Ilkeston and wider Derbyshire to take extra care and endeavour to prevent further emergencies from occurring.
The strikes will take place for eight days until Saturday August 16 between 12pm and 2pm and 10.59pm and 11.59pm.
