For those saying if you can’t do the job due to physical ailment it’s almost impossible to be pensioned off on ill health they now sack you on capability instead as it’s cheaper. Yes years ago people took the piss and reached a magic time served in the fire service of 26 1/2 years got a bad back out on ill health full pension. Nowadays you would be sacked for not been capable of doing the job, even if the injury has taken place at work, unless they are feeling very generous.
They want firefighters to work to 60 you have to achieve a VO2 max of 42, research has shown to achieve this you would have to join at the age of 20 with an Olympic standard VO2 max as no matter how fit you keep yourself age will catch you up. Niggling injuries as you get older can prevent you training and fitness decreases, sadly the pen pushers who work behind desks never experience this, it’s like raising the state pension age, how many manual jobs, joiners, labourers etc can be expected to work until then?
