Firefighters have to work only 142 shifts a year, made up of 71 night shifts and 71 day shifts, allowing them plenty of time to hold down second jobs. Yet, even with these limited hours, their pay is well above the public sector average.
Nationwide, the basic salary for a trained firefighter is £28,200 (excluding overtime), rising to £33,200 in London, significantly above the average earnings in the capital for police officers and nurses.
With overtime, that figure will be increased to anything between £40,000 and £50,000. Moreover, a watch manager in charge of up to 12 firefighters is paid around £40,000 a year before overtime.
It has already been explained in previous posts.
It boils down to if you don't want to do the shifts proposed for the money proposed, don't, there are lots of people who will.
